Not familiar with Cavalier construction is it Al sht bonded to foam laun?
Cavalier was the brand name Gulfstream used when they won the contract to bang out a few thousand FEMA trailers after Katrina. They were built about as cheap as it gets, including old style sticks'n'staples walls with wood framing, and aluminum panels stapled directly to the studs. They are noted for two issues. They are not self-contained, they had no storage tanks at all, since they were designed to be hooked up to public utilities on a semi-permanent basis. They also had extraordinarily high levels of outgassing formaldehyde. due to interior finish materials.
I guess I still don't know the problem with the out side skin. I thought the OP was referring to delamination at first but there is no laminate to begin with. Buckles in Al skins between frames are quite common and nothing to worry about.
