Here's another vote for
www.wholesalewarranties.com We have the XtraRide policy w/gaskets & seals. We went with them after having problems with Good Sam in Nov. 2012. We've used them twice without so much as a smidgen of a problem. On our 2000 Dutch Star the 4yr. policy was a little over $4k w/unlimited mileage and $250 ded. At the time we got the policy the coach was 12yrs. old and had 70k miles on it. We're now over 100k and still have over 2yrs. of coverage left. I think it's good for peace of mind for a now 14yr. old coach that will be well over 100k miles when the coverage is over.
