Big-Rig Friendly Stops Along I-70 (Denver & the Rockies)

• How to read the Big-Rig Score
• 9–10 Rolls right in
• 7–8.5 Comfortable
• 5–6.5 Workable, plan ahead
• 3–4.5 Tight
• 1–2.5 Not recommended

By Calvin Whitlock · Last updated June 11, 2026 · How we score

TL;DR: I-70 is two different roads. East of Denver it's flat, fast, and full of 70–95 ft pull-throughs — Junction West RV Park in Grand Junction (9.0), Salina KOA in Kansas (9.0), and Cottonwoods RV Park near Columbia, MO (9.0) are the easy in-and-out anchors. West of Denver it's the most demanding big-rig mountain corridor in the country: a 5.5-mile, 7% descent out of the Eisenhower-Johnson Tunnel with the most-used runaway-truck ramp in the U.S. The honest lower pick is Glenwood Canyon Resort (6.5) — back-in-only sites in a stunning canyon, listed because the location earns it, not because it's easy. We sequence the corridor west-to-east (Utah → Colorado Rockies → Denver → Kansas → Missouri) so you can read it the way most snowbirds drive it.

Every stop below is scored the same way, on the same data points, so a 9 on I-70 means the same thing as a 9 on US-50 or in Florida. For what each data point means and how the score is calculated, see Big-Rig Friendly, Defined. On this route one factor weighs heavier than anywhere else in the directory: grade. The Rocky Mountain segment is where brakes overheat, and we cover it honestly — what you can do and what to plan around — rather than waving you through.

How to read the score: 9.0–10 = rolls right in · 7.0–8.5 = big-rig comfortable · 5.0–6.5 = workable with planning · 3.0–4.5 = tight. Cells marked (inferred) are derived from terrain and road data, not published specs — confirm and help us sharpen them via the correction link at the bottom. Safety fields (clearance, grade) are kept conservative on purpose.

The corridor, west to east

I-70 enters this stretch from the Utah desert, climbs through Colorado's Western Slope, crosses the Continental Divide under the Eisenhower-Johnson Tunnel at 11,158 feet, drops onto the Front Range at Denver, then runs dead-flat across Kansas and into Missouri. The picks are sequenced in that order by exit/milepost. The two segments to respect are Glenwood Canyon (a 12.5-mile canyon with narrow shoulders and a 65 ft combination-length limit in places) and the Eisenhower Tunnel descent (see stop 13, the safety advisory — read it before you drive it).

8.5/10

1. Shady Acres RV Park — Green River, UT (I-70 Exit 164)

Your last easy desert staging point before the long climb into Colorado. Shady Acres runs many 100+ ft paved pull-throughs across a 16-acre lot — drive straight in, top off, sleep, and roll out fueled for the grade ahead. Full hookups on all 97 sites, cottonwood shade, and a flat approach right off the business loop. This is the "arrive at the edge of the desert and it's still easy" pick.

Data point	Value
Max rig length	100 ft+ (long paved pull-throughs)
Turn radius / entry	Wide, level — 16-acre lot, business-loop approach (inferred — adequate)
Pull-through vs. back-in	Mostly pull-through (97 paved sites)
Low-clearance warnings	None (inferred — open desert layout)
Fuel within 10 mi	Diesel + propane — Green River / I-70 Exit 160–164 (incl. Love's) (inferred — strong)
Grade on approach	None at the park; climb begins east toward CO
Overnight allowed	Yes
Surface / power	Paved · 30/50-amp full hookups

9.0/10

2. Junction West RV Park — Grand Junction, CO (I-70 Exit 26)

The best big-rig base on Colorado's Western Slope and the natural overnight before tackling the Rockies. Junction West has nearly 70 extra-wide, full-hookup pull-throughs, including 65 ft pull-through sites built for big rigs, with 30/50-amp service and genuinely easy I-70 access. Halfway between Salt Lake City and Denver, it's the logical "rest before the mountains" stop — flat, paved, and drive-through simple.

Data point	Value
Max rig length	Up to 65 ft pull-through (rig + toad)
Turn radius / entry	Wide double-wide sites; easy I-70 Exit 26 access
Pull-through vs. back-in	Pull-through (65 ft) and back-in
Low-clearance warnings	None (inferred — open valley layout)
Fuel within 10 mi	Diesel + propane — Grand Junction / US-50 corridor (inferred — strong)
Grade on approach	None at the park; mountain grades begin east of Grand Junction
Overnight allowed	Yes
Surface / power	Gravel/paved pads · 30/50-amp full hookups

6.5/10

3. Glenwood Canyon Resort — No Name, CO (I-70 Exit 119)

The honest one in the mountains — and the reason it's listed is the location, not the ease. This resort sits directly on the Colorado River inside Glenwood Canyon, one of the most spectacular stretches of interstate in America, with full-hookup big-rig sites and 15/30/50-amp service. The trade-offs are real: the big-rig sites are back-in only (the resort itself notes small rigs up to 30 ft for general sites), the canyon access road is tight, and I-70 through Glenwood Canyon carries a 65 ft combination-length advisory with narrow shoulders. Worth it for a night on the river if you're confident backing a 40-footer; not a casual overnight.

Data point	Value
Max rig length	40 ft+ on big-rig sites (back-in); confirm exact length when booking
Turn radius / entry	Tight — canyon access, narrow approach (inferred — caution)
Pull-through vs. back-in	Back-in only for big-rig sites
Low-clearance warnings	Canyon corridor; I-70 Glenwood Canyon ~65 ft combo-length advisory, narrow shoulders (verified Jun 2026 — drive the canyon in daylight)
Fuel within 10 mi	Diesel + propane — Glenwood Springs (~3–5 mi west) (inferred)
Grade on approach	Canyon grade moderate here; steep grades east toward Vail Pass & the Tunnel
Overnight allowed	Yes (reservation resort)
Surface / power	Full hookups · 15/30/50-amp

1308 County Rd 129 (No Name), Glenwood Springs, CO 81601 · back-in only; river-front canyon location is the payoff

6.0/10

4. Glenwood Canyon Rest Areas (No Name / Grizzly Creek) — Glenwood Springs, CO (I-70 Exits 119–121)

A daytime breather, not an overnight. Glenwood Canyon has four CDOT rest areas — No Name (Exit 119) and Grizzly Creek (Exit 121) are the practical big-rig stops with truck/RV parking, restrooms, and Colorado River access. Use them to cool brakes, stretch, and check the rig before or after the canyon's narrow shoulders. Overnight is not permitted at these rest areas, and the Hanging Lake area (Exit 125) is permit-only — don't plan to park a 40-footer there.

Data point	Value
Max rig length	Designated RV/truck parking; tighter at peak season (inferred)
Turn radius / entry	CDOT rest-area loops; canyon shoulders are narrow (verified Jun 2026)
Pull-through vs. back-in	Pull-through truck/RV lanes (inferred)
Low-clearance warnings	None overhead; narrow canyon corridor (verified Jun 2026)
Fuel within 10 mi	Diesel + propane — Glenwood Springs (~5 mi) (inferred)
Grade on approach	Canyon grade moderate; Vail Pass & Tunnel grades to the east
Overnight allowed	No — daytime rest only
Surface / power	Paved rest-area parking · no hookups

5. Denver East / Strasburg KOA — Strasburg, CO (I-70 Exit 310)

The first easy big-rig night east of the mountains, and the smart place to decompress after the Front Range descent. The KOA advertises "Big Rig Friendly" pull-throughs up to 70 ft with 50-amp service, sitting right against I-70 at Exit 310, 35 miles east of downtown Denver. Flat, simple, drive-through. The only knock is constant interstate noise — the sites back almost onto the highway — so it scores high on access, a touch lower on stay quality.

Data point	Value
Max rig length	Up to 70 ft pull-through
Turn radius / entry	Easy — frontage-road access off Exit 310
Pull-through vs. back-in	Pull-through (up to 70 ft) and back-in
Low-clearance warnings	None (inferred — open plains layout)
Fuel within 10 mi	Diesel + propane — Strasburg / I-70 corridor (inferred — strong)
Grade on approach	None — flat plains east of Denver
Overnight allowed	Yes — ideal one-night stop
Surface / power	50/30-amp full hookups; highway noise

6. TA Limon Travel Center — Limon, CO (I-70 Exit 359)

The corridor's anchor fuel-and-food stop on the eastern plains. TA Limon offers 104 truck parking spaces, CAT scale, diesel, sit-down dining (Country Pride) plus Subway, showers, and laundry — a true big-rig stop where a 60–70 ft combination has room to circulate and overnight. Not a campground (no hookups), but for fuel, a meal, and a legal sleep at the I-70/US-24 junction, it's the reliable plains pick.

Data point	Value
Big-rig parking	104 truck spaces — ample for 60–70 ft combos
Access & exit	Large travel-center lot, pull-through truck lanes; easy Exit 359
Overnight allowed	Yes — designated truck/RV overnight
Low-clearance warnings	Fuel canopies — use the high-clearance/diesel lanes, not the auto canopy (inferred — caution)
Lot surface & grade	Paved · flat plains
Fuel within ~5 mi	Diesel on-site (Phillips); propane in Limon (verified Jun 2026 — TA on-site fuel)
Cuisine / price	Country Pride (sit-down) + Subway · $

7. Goodland KOA Journey — Goodland, KS (I-70 Exit 19)

First stop across the Kansas line and a genuinely roomy one. Goodland KOA runs pull-throughs up to 95 ft with 30/50-amp full hookups, about three-quarters of a mile off I-70 on the US-24 business loop. Long enough for a 45-footer plus a toad without unhitching, flat, and quiet compared to the interstate-hugging parks. An easy first or last Kansas night.

Data point	Value
Max rig length	Up to 95 ft pull-through
Turn radius / entry	Generous — long pull-throughs, business-loop approach
Pull-through vs. back-in	Pull-through (up to 95 ft) and back-in
Low-clearance warnings	None (inferred — open plains layout)

8. WaKeeney KOA Journey — WaKeeney, KS (I-70 Exit 127)

Halfway across Kansas, WaKeeney KOA is the logical mid-state overnight: big-rig pull-throughs up to 80 ft with 50/30/20-amp service, right off Exit 127. Gravel sites and a straightforward approach. A no-drama stop to break up the long flat run between Denver and Kansas City.

Data point	Value
Max rig length	Up to 80 ft pull-through
Turn radius / entry	Easy — pull-throughs off Exit 127 frontage
Pull-through vs. back-in	Pull-through (up to 80 ft) and back-in

9. Salina KOA — Salina, KS (I-70 Exit 252 / I-135 jct)

The standout in Kansas. Every site is a pull-through, all with 30/50-amp full hookups, at the I-70 / I-135 junction — drive in, fuel off the exit, sleep, drive out, no backing at all. That's the ideal interstate-overnight profile, and flat terrain takes grade entirely off the table. Easy in, easy out, easy score.

Data point	Value
Max rig length	45 ft+ — all pull-through sites (inferred — big-rig accessible, confirm exact pad)
Turn radius / entry	Easy — all pull-through; I-70/I-135 junction access
Pull-through vs. back-in	All pull-through
Low-clearance warnings	None (inferred — open layout)

10. Cottonwoods RV Park — Columbia, MO (I-70 Exit 128A, US-63 N)

The best big-rig base in central Missouri. Cottonwoods has 63 pull-throughs out of 97 sites, all full hookups with 50-amp, about four miles north of I-70 off US-63 — far enough to escape highway noise, close enough to be an easy stop. Most sites suit longer coaches, the approach is flat blacktop, and the park is consistently well-reviewed. A relaxed in-and-out anchor between Kansas City and St. Louis.

Data point	Value
Max rig length	45 ft+ (63 pull-throughs sized for coaches) (inferred — confirm exact pad)
Turn radius / entry	Easy — blacktop approach, 4 mi off I-70 via US-63
Pull-through vs. back-in	Pull-through (63 sites) and back-in

8.0/10

11. KOA Green River Journey — Green River, UT (I-70 Exit 164)

A second solid Utah option in the same town as stop 1, useful if Shady Acres is full. The Green River KOA offers pull-through and back-in sites up to 100 ft with hookups up to 50 amp, off Exit 164 on the business loop. Spacious and flat; a touch more back-in inventory than Shady Acres, hence the half-step-lower score. Either Green River park sets you up well for the Western Slope climb.

Data point	Value
Max rig length	Up to 100 ft (pull-through and back-in)
Turn radius / entry	Spacious — business-loop approach off Exit 164
Pull-through vs. back-in	Pull-through and back-in

7.5/10

12. RV Ranch at Grand Junction — Clifton, CO (I-70 Exit 37)

An alternate Western Slope base on the east side of Grand Junction, handy if you're staging from the Clifton side or Junction West is booked. Shaded pull-through sites with 30/50-amp service and an easy I-70 approach. Mature trees are the trade-off — pleasant shade, but check the canopy over your specific pull-through if you're at full 13'6". Solid, unflashy, big-rig accessible.

Data point	Value
Max rig length	45 ft (inferred — pull-through sites; confirm exact pad)
Turn radius / entry	Established park roads off Exit 37 (inferred — adequate)
Pull-through vs. back-in	Pull-through and back-in
Low-clearance warnings	Mature tree canopy — check limbs over your pull-through (inferred — caution)

13. Eisenhower-Johnson Tunnel Descent (Straight Creek Grade) — I-70 MM 213→205, CO

This is not a place to stop — it's the segment that decides whether the whole route goes smoothly, so we score it honestly as tight. Eastbound out of the Eisenhower-Johnson Memorial Tunnel (11,158 ft, Continental Divide) you descend roughly 5.5 miles of 7% grade toward Silverthorne — the stretch that hosts the most heavily used runaway-truck ramp in the United States (Lower Straight Creek, ~MM 212, which has stopped dozens of trucks in recent years). Heavy rigs overheat brakes here. Gear down before the tunnel, not after; keep speed low and steady; never ride the brakes. Westbound has its own sustained climbs (Vail Pass) and CDOT's chain/traction "Mountain Rules" can apply in winter. Treat this as the safety heart of the route.

Data point	Value
Big-rig parking	None on the grade — no stopping on the descent
Access & exit	Mainline interstate; runaway-truck ramps at Straight Creek (~MM 212) and others between the Tunnel and Vail (verified Jun 2026 — CDOT)
Overnight allowed	No
Low-clearance warnings	Tunnel clearance fine for 13'6"; oversize permitting applies above standard (inferred — caution)
Lot surface & grade	~5.5 mi of 7% sustained descent EB; gear down before the Tunnel (verified Jun 2026 — CDOT)
Fuel within ~10 mi	Diesel + propane — Silverthorne / Dillon at the base of the grade (fuel before, not during) (inferred — strong)
Cuisine / services	None on the grade; services in Silverthorne
Big-Rig Score	4.0 — tight; drive it, don't stop on it

How we scored these

Every stop is scored on the Big-Rig Standard™: a weighted 1–10 composite. For the campground stops we weight length capacity (30%), site type & power (20%), maneuverability (20%), clearance & grade (15%), fuel & services within 10 mi (10%), and stay flexibility (5%). For fuel/scenic/route stops (TA Limon, the rest areas, the Tunnel grade) we weight access & maneuverability, overnight rules, clearance, grade, and fuel/services — the things that actually matter when you're not plugging in.

On I-70, grade is the factor that separates this route from a flat-state run. West of Denver it weighs heavily and pulls scores down honestly — Glenwood Canyon Resort (6.5) and the Tunnel-descent advisory (4.0) reflect real maneuvering and braking demands, not a thin park. East of Denver the terrain is flat, so the high scorers cluster on length and pull-through ease.

Site dimensions, amp service, pad surface, hookups, and parking counts are sourced from park and travel-center listings (June 2026). Fuel proximity and most clearance/grade notes are inferred from terrain and the road network and marked (inferred). The Colorado mountain-grade facts are cited directly from CDOT (Straight Creek runaway ramp, the 7% Eisenhower descent, Glenwood Canyon's combination-length advisory) and marked (verified Jun 2026). Safety-relevant fields are kept conservative — we flag rather than reassure.

How this list was made: We screened the I-70 corridor for stops with published big-rig specs (pad length, pull-through availability, 50-amp hookups, truck parking), sequenced them west-to-east by exit/milepost, scored each on the Big-Rig Standard™, and cross-checked the mountain segment against CDOT freight and safety guidance. Research and drafting were AI-assisted and human-reviewed. We have not personally driven every stop on this list — where a score rests on inference rather than a published spec, the cell is marked (inferred), and the grade/clearance fields stay conservative. No business paid for placement or for its score.

Frequently asked questions

What are the best RV stops along I-70?

For easy in-and-out big-rig overnights, the top picks on the Big-Rig Standard™ are Junction West RV Park in Grand Junction, CO (9.0), Salina KOA in Kansas (9.0) — all pull-through — and Cottonwoods RV Park near Columbia, MO (9.0). East of Denver the corridor is flat with 70–95 ft pull-throughs; west of Denver, plan around the mountains.

How bad is the I-70 grade through the Colorado Rockies for a big rig?

It's the most demanding big-rig mountain corridor in the country. Eastbound out of the Eisenhower-Johnson Tunnel you descend about 5.5 miles of 7% grade, home to the most-used runaway-truck ramp in the U.S. Gear down before the tunnel, keep a low steady speed, and never ride your brakes. Westbound climbs Vail Pass. Drive it in daylight and know where the runaway ramps are.

Can a 45-foot motorhome drive I-70 through Glenwood Canyon?

Yes, but carefully. I-70 through Glenwood Canyon carries a ~65 ft combination-length advisory with narrow shoulders, so a 45-foot coach plus a toad is near the practical limit. Drive the canyon in daylight, stay in lane, and use the No Name or Grizzly Creek rest areas (Exits 119/121) to break it up. Glenwood Canyon Resort's big-rig sites are back-in only.

Where should I fuel up before crossing the Rockies on I-70?

Top off on the Western Slope before the climb — Grand Junction (Exit 26) or Green River, UT (Exits 160–164) — and again at Silverthorne/Dillon at the base of the eastern descent. TA Limon (Exit 359) on the eastern plains has on-site diesel, a CAT scale, and 104 truck spaces. Don't count on fueling on the grades themselves.

Which I-70 stop is easiest for a one-night stay without backing up?

Salina KOA in Kansas (9.0) — every site is a pull-through with 50-amp full hookups at the I-70/I-135 junction, so you drive in and drive out with no backing. Denver East/Strasburg KOA (8.5) and Goodland KOA (8.5, up to 95 ft) are the next-easiest, both flat with long pull-throughs.

How long is I-70 and what states does it cross?

I-70 runs about 2,150 miles across ten states — Utah, Colorado, Kansas, Missouri, Illinois, Indiana, Ohio, West Virginia, Pennsylvania, and Maryland. This page scores the western half, Utah through Missouri, where the big-rig story is the Rocky Mountain crossing and the long flat Plains run. The eastern states are a separate, narrower-interstate story we cover elsewhere.

Where does I-70 end on the East Coast?

I-70's eastern terminus is in the Baltimore, Maryland area. East of Missouri the road runs through Illinois, Indiana, Ohio, a short stretch of West Virginia, then the older, narrower Pennsylvania section before Maryland. We score the western Utah-to-Missouri half here; the named parks on the eastern states get their own corridor pages as we build them out.

Where are the best big-rig stops on I-70 in Kansas?

All three of our scored Kansas picks are flat, easy in-and-out overnights. Salina KOA (9.0) is every-site-pull-through at the I-70/I-135 junction; Goodland KOA (8.5) runs pull-throughs up to 95 ft just across the Colorado line; WaKeeney KOA (8.0) is the logical mid-state stop with pull-throughs up to 80 ft. See each scored listing above for the data we used.

Where should a big rig stop on I-70 in Missouri?

Our central-Missouri anchor is Cottonwoods RV Park near Columbia (9.0) — 63 pull-throughs, all full-hookup 50-amp, about four miles off I-70 via US-63, far enough to escape highway noise. It scores among the easiest stops on the whole route. Check its scored listing above for the maneuvering and hookup details behind the number.

Should I take I-70 or US-50 through the Colorado Rockies in a big rig?

Both cross the Rockies and both demand respect. I-70's defining hazard is the 5.5-mile, 7% Eisenhower-Johnson Tunnel descent with the most-used runaway-truck ramp in the country. We score each route's stops on the same Big-Rig Standard™, so compare the actual numbers rather than the reputation — see our US-50 stops page alongside this one and pick by your rig and your braking confidence.

Can I sleep in a Walmart parking lot with my RV along I-70?

Sometimes, but never assume it. Overnight RV parking is set store by store and by local ordinance, so a Walmart that allowed it last year may not now. Always go in and ask the manager, and treat it as a backup, not a plan. On a long run like I-70 we'd rather point you at a scored, full-hookup stop above where you know the rig fits and the power is real.

What stores let RVs stay overnight on a long interstate run?

Some Walmart, Cracker Barrel, Camping World, Cabela's/Bass Pro, and large travel centers permit overnight RV parking, but every one is case-by-case — local rules and manager discretion decide it. None of it is a substitute for a planned stop. For I-70 we score real overnight-capable stops above, including TA Limon (8.0) with 104 truck spaces, so you're not gambling on a lot at 10 p.m.

Where is the best place to park an RV for free overnight on I-70?

The honest answer is that a free spot is a backup, not a strategy — large travel centers, some big-box lots, and certain rest areas allow it, but rules vary by location and many forbid it. On the Colorado mountain segment, do not improvise a free overnight on a grade or a canyon shoulder. Use a scored stop above; where overnighting is barred (the Glenwood Canyon rest areas, the Tunnel grade) we say so plainly.
