I cut a big hole!!! IN MY CAMPER ROOF
I am STILL screwin' with this between thunderstorms. But I made a big score. There's a little store in Spokane, the "Junxtore" that has a bunch of "junk" and a RACK of thick aluminum sheet. I'd bought some there, made the dash for the old Sea King boat out of that, but what I have left would have to be joined to be long enough......to make the intended wind deflector for the front of the top.
Yesterday I went in and spent 100 on aluminum. One piece is the perfect width, and even has the protective plastic on one side. Cut it to length last night, and rounded the top corners, and WAS gonna get it on there this morning. But it rained last night and is very threatening this morning. It's only 6:50AM as I'm typing this
I don't have photos yet of the so called seals
For the front hinge, I cut open a motorbike tube and incorporated that with the hinge, which already has a backing strip and several (now) bolts across the front. That should be pretty tight, especially with the front "windshield."
Along the sides are the factory seals, which seam fairly tight, and they, atop the factory frame, sits on the inside edge of flat pressure treated 2x4's. These are heavily caulked to the roof. So outboard of the frame, and still on top of the 2x4's I fastened 2/4" foam plumbing insulation to act as seconary seals, and they "nussle" right up and into the curvature of the factory ones. Then, just outboard of the 2x4's I cut "splash shields" out of the left-over roof material, and screwed them, vertically, to the outboard sides of the 2x4's. They are very close to the top of the bed cover. So "coming in" from the outside, you have the splash shields, the plumbing foam, and then the factory shields. THEN you have tent material which is itself at least somewhat waterproof.
For the rear, I have not yet done anything.
