I highly recommend the AAA Premier RV roadside assistance program! It's around $150 for the year, and you can add someone in your family, or a friend (who can travel with you on this trip) for around $50 extra. They will get their own allotted tows, and if with you, will be able to use them on your RV's behalf. If you can travel to the RV, this should work perfectly. They say it takes a week for full tow benefits to kick in, but I've had access to all my tows after just a couple days of registration. You get two 100 mile tows and one 200 mile tow per beneficiary. For around $200 that is 800 miles covered with two folks on one account!
Highly highly recommend, and also unaffiliated with AAA, just stoked that I was able to move an old project '77 Toyota Dolphin to a friend's a few hours after signing up with them. Had my newer rig break down within two days of registration and had it towed 10 miles so I could work on it somewhere safe. Was told if I had reported myself as being in the middle of a trip, they would have covered the cost of food, lodging and possibly repairs.
