I would use the warranties that come with all of the different items in your coach, most are for a year. Heres my thoughts on extended warranty, of which I have. Yes its great to be able to fix things your self, tighten a screw here, glue something there. If you are like me, I can not fix a microwave, or replace the roof etc. Some will say take the monthly payment you would spend on the warranty and put it in the bank for repair use. That's a great idea, if you can do it, I can not. I have the Good Sam extended warranty, and have used it in the past for my tv. It saved me a bunch of money. I have not used it on my currant coach but its there if needed. The key is having the repair shop contact the warranty folks first to find out how and what has to happen. If taken in order its not that big of deal.
