Extended warranties
I use American Guardian for my 93 Winnebago, as none of the name brands such as Good Sams will warranty anything older than 10 yrs old. It was a learning experience figuring out how to properly file a claim, finding service people that will deal with them, getting pre-authorization etc, but once I got past that, they have been pretty good, as long as you follow the very specific steps. A 4 year warranty cost me just over $1600.00, and in 2 years time, they have paid out 4 times that amount in repairs.
