I bought a 18 footer that is 15yrs old and gutted it down to the frame and aluminum tube frame walls. I found one cracked wall stud. That I rewelded and I added a electric side mount toungue jack. Then 2” of spray foam all around and 3/4” knotty pine car siding and 12v and 120v wiring. Then 3 bunks weighting in at 3750. But is nice knowing that the frame will never rust or have to paint. Don’t treat it like poop and it will last forever.
