I'm new to this RV'ing thing and having problems with my very new motorhome. The service where we bought it has not helped at all. The very first problem we had was upon taking it home and plugging the electrical into our garage, poof, both TV's and microwave went out. When we tried to get service we were told it wasn't covered and it was something we did and we'd have to pay. A friend checked out everything and it turned out we blew fuses in all the above. We can't get any answers from the dealer and want to know if the 50 amp 4 prong plug can be plugged into 220? Will this damage the system? The dealer said we can only use 110 but the book reads 220 (unless I'm not reading it right). Has anyone else had any difficulty with this?
