Lower body panel replacement

[cosmic]

Here is a couple of pictures of how to fix that wood problem with 2 sheets thick 3/4 inch  plywood. it took me 2 days to change all the wood all the way around the rig. should be good for a while i hope. The wood goes up about 18 inches then its foam all the way up. the big screws holding everything screw into the floor under the body trim. mine is solid as a church now.

Pulled out the window trim and caulked underneath seamed to work for now.
The roof from what it looks like to me. guy before me put a seamless sheet of aluminium over the hole roof. bent all over the sides and then installed a drip edge. i check and replace the caulking where needed every season so I'm not really worried about a leak all that much.
