We did not have to pay for tow with an add-on - at least with GMAC. We had bought a used small 5th wheel & truck for an Alaska trip and the truck died enroute. The truck & the trailer were both towed 75 miles. The trailer was set up in a campground and we had to rent a car until we decided what to do. No charge for anything. (We ended up going back to 'start' and continuing our trip with our normal 'home' - our 40' motorhome) and had a wonderful Alaskan trip. Should have stayed with it in the first place. :)
