RV Campsite Fit Calculator (Rig Length vs Site Length, Back-In Clearance, Turning & Height)

How it works

combined length = RV + tow vehicle (+2 ft ball hitch; −4 ft fifth-wheel bed overlap) · fits hitched if combined ≤ site; fits unhitched if RV ≤ site · back-in swing road ≈ 0.75 × trailer length (0.9 × motorhome) · clear width = 8.5 ft body + slide + walkway

Campground listings give a site length, but they rarely say whether it means the pad, the pad plus the parking spur, or the whole rig — and reservation systems ask for "equipment length" in different ways. The safe method is to know your real hitched length and your RV's length alone, compare both to the site, and plan to unhitch when only the RV fits. Back-in sites need road width to swing a trailer, older loops were built for much shorter rigs, and height limits on the way in matter more than at the site. This calculator turns your measurements into a yes, an unhitch-first, or a no.

Worked example

A 32 ft travel trailer behind a 20 ft crew-cab pickup is about 54 ft hitched, so a 45 ft back-in site only fits once unhitched — and the 13 ft of pad left over will not take the 20 ft truck, so it parks in overflow. Backing a 32 ft trailer through 90° wants about 24 ft of road, so the 20 ft loop road means a few pull-ups. At 11.5 ft tall the rig is typical: watch for parkway and tree-canopy limits; the 3 ft slide needs 11.5 ft of clear width plus a walkway.
