Been lucky that I have never had more than a half day break down in 40 years of RVing. I like the idea someone said about bring the title along, I may have to consider that. I always figured if I have a breakdown that was not fixable or to expensive, I would get rid of the equipment and find a substitute or rent a vehicle and either finish the trip in motels or head home.
The two worst break downs I personally know about happened to friends. One was a transmission. They were close to where they were going (meeting us) when the transmission died. They had it towed to a transmission shop, rented a van and loaded what camping gear a such they could and met us. Bit rougher camping than planned but 3 days later they got the call that is was done and retrieved it and finished their stay, a few thousand dollars poorer.
The other was a bigger break down, a friend of my parents had a big diesel pusher bus conversion and blew the engine. They located a place that would rebuild it but that is a multi week job between getting it scheduled, getting parts and rebuilding. They rented a car and drove home, then flew back a month or so later and paid an even bigger bill and drove home.
