This RV’s published size (25′ 6″ long, 7′ wide, 11′ 2″ tall) checked against the RV rules at 14 popular national parks.
- Doesn’t fit
25′ 6″ long. Vehicles and combinations are limited to 21′.
- Doesn’t fit
25′ 6″ long. The limit is 23′.

25′ 6″ long. Old Fall River Road is limited to 25′.
- Doesn’t fit
25′ 6″ long. Artists Drive is limited to 25′.
- Restrictions
25′ 6″ long counts as oversized: park in Lot 1, Lot B (30′ and under) or Lot D. Hermit Road is shuttle-only most of the year.
- Restrictions
Main roads are fine, but six scenic roads, including Roaring Fork and Rich Mountain Road, ban RVs and trailers of any size.
- Restrictions
25′ 6″ long. The park advises against vehicles over 22′ on the climb to Giant Forest and bans them on Moro Rock and Crystal Cave roads. Use the Big Stump entrance.
- Restrictions
Vehicles 23′ and longer can’t park at the main viewpoints mid-April to mid-October. Use the shuttle or the Southern Scenic Drive viewpoints.
- Restrictions
No length limit, but only 42 oversize parking spaces park-wide. The park suggests leaving big rigs in town or at the visitor center.
- Likely fits
Passes on paper, but the limits include mirrors, A/C and racks. Measure before you go.
- Fits
Fits 9 of 10 campgrounds, including Fishing Bridge RV Park (hookups). Towing a car adds to your length.
- Fits
Fits 9 of 10 campgrounds that take RVs, including Lower Pines and North Pines.
- Fits
11′ 2″ tall clears the lowest underpass (11′ 8″). Cadillac Summit Road is closed to RVs.
- Fits
11′ 2″ tall clears Marys Rock Tunnel (12′ 8″).
Published dimensions usually leave out mirrors, awnings and sometimes roof A/C, and many park limits include them. Rules were checked against National Park Service pages on October 27, 2026 and can change. Confirm with the park before you go. Full park rules & sources
How long can you boondock?
Estimate how many days of dry camping (no hookups) this RV’s published tanks allow for your group.
How this is estimated
Tank sizes are the manufacturer’s published capacities. Daily use is an estimate per person: sinks and dishes 1–3 gal, toilet flushing 0.5–1.5 gal, drinking and cooking 0.5–1 gal, and 2–8 gal per shower, depending on the water-use setting. Sinks and showers drain to the gray tank; toilet water plus about 0.25 gal of waste per person goes to the black tank. “Mostly park or vault toilets” counts a quarter of normal toilet use. Real use varies a lot, and tank gauges are often inaccurate, so plan to leave a margin. Battery power and propane can also limit a trip and aren’t included.
