I've tried about every kind of camping, tent, popup, trailer, and motorhome. I've gone back to a tent, if I can get my vehicle to the site I can camp there. With all the other types you are kinda limited as to where you can camp.
I do a good bit of camping here in Kentucky at a place called LBL and most of the places I camp you can forget about getting to if you are pulling a trailer or driving a motorhome. In fact some spots are by boat only, unless you have a good 4x4 and if it starts to rain you better get of there or you arent gonna get out.
Now LBL has some very nice campgrounds with water, electric all that stuff they charge by the night for them. There are also lake access campgrounds that have sites with tables and fire rings. It is $15.00 a year for a permit that allows you to back country camp just about anywhere in LBL (170,000 acres). With a tent I can find a secluded camping spot just about anywhere, even in the middle of summer.
