I have a '72 Compact with a lot of rot on the wooden sill that appears to hold the walls to the frame of the trailer. I can push a screwdriver right through them in some spots. I don't have an enclosure that would allow me to remove the skin or walls to work on this.
Can anyone suggest a way that the sill might be replaced a section at a time without tearing the whole trailer apart? Would the remainder of the structure provide enough support to hold the rest of the wall together while a portion of this lower sill was removed? Could this be done one wall at a time from inside the trailer?
Any advice would be gratefully appreciated. The camper is useable, as is, but I envision the whole thing just crumpling off of its foundation someday like an old barn.
No shed here, either. I replaced both pieces for wall and floor from the outside by peeling up the bottom edges of the skin. Did them in sections, from rear corner to wheel well, wheel well to door. The problem with only peeling back one section of skin at a time is you tend to get creases in it from trying to get that last half-inch of space to keep from slitting your wrists on the aluminum, unless you undo the whole length of skin at once. And make sure you jack the wall back up into its non-saggy position before you mount the new wood. Don't depend on the studs over the wheel wells to support the whole wall in its proper position.
