If you try to stay in some of the state and federal parks you will find that you are simply too long. And width comes into play too in some places. Even the access roads will often be a problem. Too narrow with many trees.
But if you stay mostly in commercial parks you will have little or no problem except for some of the older parks. But you probably won't be wanting to stay in those anyway. Often they are populated with rigs that have been there so long they have sort of melded into the surroundings.
Join us at Q this coming January and you'll have no trouble fitting into whatever site you want!
Congratulations on the rig! Enjoy and travel safely.
