Sorry for being so slow on my updates. I have had 12 big trees removed from my yard, been working on and attended my 50th High School Reunion, and its either been 90 deg or raining in Georgia for a while. For me, the deciding on, what I am doing and the way I will do it, takes longer than the doing.
I am slowly putting some things back together. It is evident, the luan plywood is bad, it gets wet and turns loose the Filon. I can not eliminate the wood from the side, unless I was to remove the side. I can eliminate the wood from the front though. I have removed the lower front panel, and the inside piece of cardboard-wallpaper from the inside. I sanded the alum frame and added an extra rib to the frame. It seemed weak with no support in the middle. I chose plastic 2" X 3/4" trim from the big box store. Lighter than the Aluminum and I could mount it with zinc plated L brackets and stainless screws. I don't have a Tig welder. I used new insulation and on the inside I used aluminum flashing installed with aluminum pop rivets. The inside is not visible because it is hidden by the mattress.


I have installed the panel, rewired my lights for just the 2 outside lights and am ready for the next step. I plan on an alum sheet before the outside layer of Filon. I need to make up the thickness between the camper frame and Filon. (because of the luan is thicker than the sheet aluminum I will be using. My thoughts are to maybe use flashing tape across the frame/Styrofoam.
My immediate work will be cutting a patch panel of luan and building a clamp method to repair the side of the front which was damaged. I have decided to use the Loctite Premium construction adhesive. I have chosen this because it is recommended for everything. It would be to complicated to use contact cement because I am not removing the whole panel, just pulling it back and inserting a luan patch.
