I just returned from a 14,000 mile round trip journey to Alaska. Experience of a lifetime. Went to some extremely remote places. Before we left we purchased a Roadmaster Spare Tire carrier, spare tire and custom cover. Never had to use it but, knowing my luck, if we hadn't taken it, we would have needed it. I have a very unusual tire size (in fact had trouble getting a new one from the local Goodyear dealer before we left). Had a satellite commicator which I would have used to get help.
Our service provider would have come from FMCA (hopefully).
