I have seen them tow both. Or they will send two tow trucks to tow them both in. Lots of time they will tow you to a campground or call a campground and they will come out and pull you in. Lot of nice people in campgrounds. Never heard of anyone being left stranded for very long. Maybe someone else has.
I have the GoodSam's Club emergency road service and they guarantee they will take care of both the RV and the Tow vehicle, including the tow dolly, if you have one. (I don't think you ment "TV", I hope, never heard of a TV having to be TOWED), ha ha :laugh:
