Yes, my warranty literature also says that both the general and the roof warranty are to the original purchaser only, and furthermore, that owner must have sent in the registration card within 30 days to activate the warranty. Sorry, but don't think either Jayco or Alpha sytems will honor a warranty under your circumstances.
