I recently purchased a new 2004 Jayco 26S trailer. The salesperson tried to sell me the usual extended warranty and a high tech sealer(s) process. I'm certainly familiar with the sales pitch as I've purchased new vehicles before. My personal feeling is the warranty never pays for itself, and these "so called" sealers/clear coats are nothing more than a fancy wax job and some 3M Scotchgaurd for the cloth components indoor. Does anyone have any thoughts on this subject?
