I purchased a 34' Coachman Classic from a long time (now EX) "friend" Anyway.. The trailer roof leaks bad. The story I got after the fact is that the pervious owners used the trailer on the infield at Daytona for the races and partied on the roof.. the roof is now like rice paper.. you can not walk up there on most of it. I repaired a few section with some rolled stuff from home Depot that really did a good job,, but, I still have leaks and can't find them.. i think it's coming in around the roof top A/C unit. I only have about $1,850.00 in this thing so putting a little money in to a roof repair won't kill me,, but, I don't have a clue where to start or how.. Anyone have any experiance with these sorts of things???
