I'm not H$X$, but I had an experience just yesterday that seems relevant.
I drove up the Kern River valley in CA yesterday just to look around. I cruised through many of the campgrounds that were open just to see what the spaces were like. Half had a little more than just enough room to park a car or pickup. A few had enough room for a very small trailer, maybe a pop-up or tent trailer, and a smallish tow vehicle. A handful had enough room for an RV, like a small motor home and a tiny toad.
And a couple or three had enough space for a trailer like mine and the tow vehicle to be able to park in the space given at the camp site.
No where did I see a sign that said there was a length limit in these concessionaire run USFS campgrounds. Length was limited by the spaces available, not by a rule that I could see when I entered the campground.
There were some primitive camping sites that could accommodate larger trailers, maybe up to almost thirty feet, but there was no way anyone was gonna get a big trailer or motor home in there and be able to maneuver around. The turns were too tight with rocks in the way, large rocks and small boulders.
There doesn't have to be a length rule if the rocks will enforce their own.
