Every other site tells you "most rigs under 35ft are fine." We show the real, per-site number — sourced from the campground's own listing, not a guess.
Enter your rig's real dimensions and we'll filter to sites that actually work — no more arriving to find your 38-footer jammed into a 24ft pad.
Length, width, slide-outs, and rig type — the exact dimensions that determine whether a site will actually work.
Sourced from Recreation.gov's RIDB and state-park booking data — the same structured fields the campgrounds themselves publish, not an aggregate guess.
See sites sorted by best fit, with driveway type and hookups, so you know before you go — not after you arrive.
Illustrative preview of the campgrounds in our sample dataset — full national & state park coverage is the launch target.
Every other site recycles the same aggregate stat. We use the actual structured field the campground publishes for that exact site.
Every region below links to real Recreation.gov site-length data across its states — no rounding, no averages.
