About RVFitFinder
RVFitFinder exists to answer one question that every RV owner has asked while staring at a booking screen: will my rig actually fit on that site?
Why this site exists
Most campground listings describe RV access in vague terms — "big rigs welcome", "RVs up to 30 ft", "some sites accommodate larger units". Those phrases are written at the campground level, not the site level, and they are the reason people arrive with a 38-foot fifth wheel to discover that the only site they could book is a 28-foot back-in with a tree at the entrance.
Federal campgrounds on Recreation.gov actually publish a maximum vehicle length for every individual campsite. That number is exactly what you need, but it is buried three or four clicks deep on each site's page and there was no way to search across campgrounds by it. RVFitFinder pulls those per-site figures together — currently more than 31,000 campsites — so you can type in your rig length and see, campground by campground, how many sites genuinely fit.
Where the data comes from
Every site length on RVFitFinder comes from the Recreation Information Database (RIDB), the public API behind Recreation.gov, used under its published API terms. We ingest the campsite records, keep the maximum-vehicle-length attribute the campground itself reported, group sites by campground and state, and show you the counts. We do not estimate, interpolate or "round up" lengths. If a campground has not reported a length for a site, we say so rather than guessing.
Because the source is a live database maintained by the agencies that run each campground, figures can change when a campground is renovated, re-surveyed or re-listed. We refresh our copy periodically, and we always recommend confirming the site details on Recreation.gov (or with the campground) before you book. If you spot a figure that looks wrong, tell us and we will check it against the source record.
What we cover — and what we don't
RVFitFinder covers federally managed campgrounds listed on Recreation.gov: national forests, Army Corps of Engineers lakes, Bureau of Land Management sites, national parks and similar. Our separate RV parks section covers private parks with an RVFit Score based on the amenities and rig-friendliness they publish. We do not currently cover most state parks, county parks or dispersed camping, because those systems do not publish per-site length data in a form we can verify.
The guides are written in-house to explain the things the numbers alone can't — how site length is measured, how much margin to leave for a tow vehicle, what "maximum vehicle length" does and doesn't include, and how to choose between pull-through and back-in sites.
Who runs it
RVFitFinder is an independent, one-person project built and maintained by Ciprian, a developer who got tired of the "it'll probably fit" school of campsite booking. It is not affiliated with, endorsed by or operated on behalf of Recreation.gov, the National Park Service, the US Forest Service or any campground operator.
The site is free to use. It is supported by advertising (see our privacy policy for what that means for your data) and by readers who buy us a coffee. We do not sell rig-length data, accept paid placements from campgrounds, or let advertisers influence which sites show as fitting your RV.
