Hey all I have a 1989 Skamper 100s AWSOME camper works great but now I have the common roof problem, it leaks in the center right were the two aluminum sheet pannels meet, thats an easy fix ill just re seal that. but it did damage to the styrofoam (cracked it) and now the roof sags some in that one spot. question one how does one go about fixing that problem? where do you get the materials to do such a repair? Next the back of the roof were the rear torsion mounts are seem to be twisting slightly and the rear corner caps are broke, so from what iv read i need to replace the plywood on the outer part which is two 1/2" pieces glued together. but how do i go about this does anyone have the step by step instructions? I know people on here have done it and they have come out great, im just leery of doing it seems like those mounts have alot of pressure on them, and how do i repair that wood without destroying the roof? and when its all said and done how do i replace the corner caps, im guessing their not available anymore. please advise!
