When i was US in 2007 i said to the wife "look at at guy driving right behind that big bus", as i drove passed i then realised that your motor homes come with its own car : 
Well, it doesn't exactly "come with it's own car". Most people either have a car (once hooked onto the RV it's called a towed) or purchase one. Kinda difficult running down to the local store with the "bus".
