Every site has a limit. Your rig has a length.
We match the two, one campsite at a time, across every federal campground that publishes its measurements, and show where every number came from.

58,761 of 115,481 bookable federal campsites take a 35 ft rig.Answered at 35 ft, the next step above your 32: rounding your length down would count sites that might not take it. Counting only sites that publish a limit for that rig class. A site publishing none is unknown, and unknown never counts as fitting.
One advertised length describes one site
Every listing everywhere shows a single “max RV length” per campground. That number is the longest single site on the property, and at 635 campgrounds here, each with more than ten sites, it is a length exactly one site achieves.
The advertised number proves such a site exists. It says nothing about your odds of getting it. So this site keeps the per-site measurements the agencies already publish, all 87,506 of 115,481 bookable sites that state one for a rig, and answers from every one of them.
