I guess I have to take the other side, I am glad I have the warranty. We bought a 2007 Sun Voyager four years ago and without the warranty we would be out of pocket in excess of &10,000 dollars. I am all about fixing issues myself, but Diesel engine issues are beyond my expertise. Turbo replace ment, warped manifold, fuel pump amongst other issues has made having extended warranty well with the cost. Now my situation is probably not the norm so probably shouldn’t go by my luck.
