Dealing with rotted studs and flooring

You can do it and don't let the armchair engineers tell you not to. I'm assuming throwing away an otherwise serviceable RV is not the way you want to proceed.

Look at the build thread in my signature line, the Cowboy/Hilton. I replaced frame and flooring and it is all pictured there. If you have a particular question, let it fly or shoot me a PM.

Thanks westend. I guess my biggest challenge is securing the new framing to the aluminum siding. I can remove the old from the siding with a sawzall but I'm not sure how I'll secure the new since the studs are screwed from the outside in. Construction adhesive is one alternative but I'm not sure how well it will adhere to the aluminum.

Most aluminum siding on Rv's is not fastened to every framing member. If you have a bad corner section, remove the trim rail that covers the corner, remove staples or screws that fasten the siding to the studs. Remove siding by removing screws or staples that fasten it to studs, top plate, and bottom sill.

I think you'll find that the floor sheathing is underneath the wall. With judicious use of a sawzall, grinder, or a small reciprocating saw, I was able to remove fasteners that attach the wall bottom sill to the frame. I then slid new sections of plywood floor underneath the wall framing and reattached the wall through the new floor. I also replaced some floor joists and sistered new joists underneath any new floor joints that I created. While I was pulling floor, I insulated the open space between joists with foam sheets.

Construction adhesive like PL400 or Liquid Nails should be your new best friend. It sticks to anything clean and I used some in every joint of the framing I replaced. It helps to hold everything together when the trailer is in motion.
