For 20 years I was camping at the same lake that had several campgrounds.
I prefer the one who was under construction and for couple of seasons free of charge.
Driving 40' conversion at the time I had a favorite spot and knew about 6 more spots where I could fit.
Then another season come and they made the campground fees, put host at the gate and made "max 32' rule"
I went there and the host informed me about the rule, but after hearing that I've been parking my bus there for years, he "let me try"
Obviously I could not make the 1-way loop and had to go 50' against the traffic, but as always my bus fit with lot of space to spare.
But I was doing that in mid-week when only few sites were occupy. Don't try to do it Friday night.
