We used to stay in state and fed parks in Kansas frequently with no problems with length (ours is 36' 4"). We have seen a few state parks, particularly in California, where there are few, if any, sites large enough for us. But in most places we've not had a problem. To tell the truth, we've found plenty of great sites where we can enjoy the comfort the size of the Montana provides and that's important to us. If those parks you would frequent would be a problem getting into, then that, of course, has to be a factor in your buying decision.
Good luck.
