Ford includes towing to the nearest dealer during the warranty, but only for chassis-related problems.
Coach-net also tows to the nearest service center (Ford for chassis stuff, RV center for other problems) and will cover tows for non-chassis problems like stuck levelers, stuck slide-out etc.
I have AAA RV+ because I would generally prefer to be towed home, or if I'm on the road have the option of taking it to a repair shop of my choice within 100 miles.
I have worked with Coach-net as a vendor, and they will go out of their way to provide the necessary services. However their dispatching involves fax machines and phone calls, so it can take many hours to source the right equipment vs AAA who electronically dispatches the nearest capable truck usually before you get off the phone (at least in this region... I've read rumors that may not be the case in other regions).
