I recently purchased a "99" fifth wheel with two slideouts.Upon recent inspection from the roof with the slideouts in the out position I noticed a piece of the weatherstriping/gasket torn loose from the center area on both slideouts.It appears the previous owners attempted to repair the loose pieces with duct tape.The tape has since disintegrated leaving the pieces loose again.It does not appear to be something one can repair successfully.The stripping appears to be held in place by rivets as I look from the outside but possibly this is not the case when I examine it from within the unit when the slideout are retracted.Access from within looks difficult.So far no leaks but I would like to remedy the problem.Do I have to see a dealer/repair center or is there a way for me to make it right myself?
