IN many years of RV travel we have only had one problem that stopped us and caused a week long delay. As it turned out, this happened to be right outside of Dutch John, UT. We had passed through the little town when we broke down. There is ONE small garage in Dutch John and CoachNet sent the mechanic out to us in about 20 minutes. He was able to do a temporary repair that got us back to the RV Park in Dutch John, right next to his garage. He determined what the problem was and we ordered the parts. We ended up spending a week in a fantastic area of Utah that we would have driven right past. This incident changed our "schedule" but it did not hurt our trip. As it turned out, had it not been for the problem we would have missed a great destination. He completed the repairs, gave us a bill that was way less than I expected, and we continued on our way with a note on our map to return to Dutch John the next time we are in the area.
One of the advantages of having an RV and a toad is that a problem does not mean that your trip has to come to a halt. There are usually alternatives that will allow you to just switch gears and enjoy the circumstances that you are in.
