Taking the rear belly pan off was the easy part. Clean and seal frame members, foam insulate, and then install a new bellypan. The .025 Aluminum is on order, big head rivets on order, and I have an idea for holding the new belly pan in place while I drill and rivet.
Here are a few pictures I thought you would be interested in. You can see from the pics that my rear most frame cross member is rusted through. Standing water and wet insulation likely caused this. I figure the water gets in there through the rear sewer hose storage compartment, and the rear "bumper wraps" on each side of the trailer. There is no factory sealing system in these areas. My thinking is to provide a belly pan drain and air vent in this area so the water can get out and dry up.
Nothing like laying on the ground under an old Airstream with Minnesota mosquitoes festing on my face!
just paint it with por-15
