Aw yes, the extended warranty. About "seals" being covered. My coverage has that, however, the insurer has a strange definition of "seal". To them all seals are "weather seals" which are not covered with our exclusionary policy. As to being in the shop for 7 months, it means nothing. If you did not buy from that dealer, you go to bottom of the list and they get to you when they have time. The warranty companies only pay so much for a covered item, which is similar to how the gov reimburses doctors for their time, way below market rate. So shops have little profit incentive to put your problem to the top of their list of things to do. We did purchase an extended plan, but we have very complex computer systems and a Cummins engine and Allison tranny to think about. We paid $6k for a zero deductible unlimited mileage 3 year plan on our motorhome. Little things add up. Labor is expensive, more than parts usually. We are over half way in getting our money back. We will be taking this outfit to arbitration at some point just because of all the nonsense they come up with to not cover something. And I will say, since using the word "arbitration" we have gotten better service from them. One of our computer systems is currently being fixed at which point we will be just about even with the money we paid. A major rebuild on a Cummins 500 is $30k to $40k, and it does happen. The tranny? No idea what that would cost for an Allison mh4000. If you're handy, save the money and fix things yourself. Maybe a cheaper policy for major component items? If you buy a policy, be prepared for the fun and games with the insurer. An example, had to have a switch replaced. A covered item but the insurer would only pay for half, I had to pay the other half. Does that make sense? Wasn't a lot of money, but it's one of the reasons we will be going to arbitration. To me a covered part is a covered part. Another example; a seal on a slide out. I say it's a covered seal, the insurer said no, it's a weather seal. That being the case, seals being covered is a joke. Good luck and read what they don't cover very closely.
