Run away unless you are going to replace the roof with a new one. They are ABS and nothing sticks to them but abs. I tried patching my cracks with a abs flakes and mek solution and they came back, next step was rhino liner which last about one year before it started cracking. More than likely the roof also has some bowing where there is a gap in the from and back allowing water in while traveling. I really enjoyed my Coleman except for the roof, I ended up buying a late model used roof from a salvaged trailer and had it shipped from CA to TX.
