Refrigerators are only a few hundred bucks, since he is a DIYer. Just replace cooling unit. During the first 7 years of owning this Revcon, I spent well under the average for upkeep and repairs, compared to much newer coaches. The reality is, that the rate at which stuff breaks starts to fade in between the 5th years and 10 years in age. It then continues at that rate for the rest of its life. The failures are not as catastrophic, but still seem to cost just as much to repair. Unless you have a major drive train component failure, all other repairs are about equal in expense. In a gas coach it is not uncommon to start replacing suspension components at the 10 year mark. A newer coach will have 22.5 tires, which is great for the load carrying, but super expensive on the pocket book. A lighter coach will not require the larger tires, which saves several thousand dollars.
