bought my 189fdr 2nd hand and after checking it out found the seam above the bed was loose. When i pulled on it it came right off and exposed the water damaged Lauan board. I pulled all the boards off and found the wood frame aorund the window and the back was rotted and the fiberglass insulation was soaking. After removing the wood and the fiberglass insulation, the wall (i think it is filon with some paper type of backing ) was soaked too. The paper stuff came right off leaving the filon (white rubbery stuff) so i removed to let it dry. I am starting to rebuild but can't figure out what this paper backing to the filon is and is there a special way to put it back on ?
Update Sep 6:
after a lot of work, found that this is how FunFinder keeps the weight down by laminating the front fiberglass to heavy paper. Unfortunately i think this contributed to the failure of the seals near the window and the two lights up front where a lot of the leak seemed to have started. Now working on rebuilding the whole front including some of the sides wheret he water leak seemed to have got in too. So need panesl, rebuild the wood frame around the window, remove all paper and clean the fiberglass and replace with lauan boards and of course recaulk everything.
Unit was originally sold to a dealer in Ontario who must have detetected the problem. Unless you really know what to look for, this would have gone unnoticed for years as the damage got worse. Of course the dealer then decides to sell it without repairing it. And I of course bought it from the guy who bought it from the dealer. A whole bunch of dishonest players in this. To me this will be a long project but one that i will not walk away and dump on a poor unsuspecting buyer.
So, please check the caulking around the windows up front, the lights and all the seams. I have time to work on this.

Finally figured out what that paper looking stuff is, it is MDF and when wet simply disintigrate like paper.
