Most of the campgrounds I have stayed at have catered to RVs. Many of those however seem to have converted to just R. The only V in their future will be taking them to the junkyard. Functionally, this means a lot of gravelly campsites, I recommend a footprint to save your tent's floor. We could probably be more helpful if we knew when you were planning to go, where you planned to start riding, any dietary restrictions, etc.
Good luck!
