I suggest if you are sure of an RV also get a car you can tow along like a dingy. You park your RV and take car into town; the RV is like a movable camp from which you come and go. Also get a roadside assistance insurance like Good Sam Club in case you are somewhere and need a tow or have to change a tire. There is no way you can change a tire by yourself if you have a 37 footer RV.
Also it is great to park overnight in a Walmart parking lot if you are on your way somewhere. Walmarts are good that way.
Problem with Good Sam Club, owner of Camper World said that he doesn’t want Trump Supporters in his stores.
