I would not ditch an RV just because of its age. We have a 1990 Winnebago Warrior. Everything works except the cruise control, and I can't get parts for that anymore. It only has 67,000 miles on it, so I'm sure it has at least that many left in it.
My advice is to get a Good Sam membership. Our RV has crapped out on us a couple of times (fuel pump relays, then fuel pump, plus we blew a heater core just as we pulled into Disney) and Good Sam has been worth every penny just form the towing costs saved.
$60K can buy a lot of gasoline and repairs if you need them.
