You are still confusing the issue.
Many aluminimum skin units come with aluminum frames. This is not a new thing. I recall my Dad grumbling about the wood frame on the old trailer failing when he got a new aluminum skin/aluminum frame trailer in 1978.
Do you have any specific examples, such as manufacturer and model, of an aluminum sided aluminum framed trailer made today. I'm aware of Airstream, Livin-lite, and AVT along with some off brands like Work and Play. Run of the mill aluminum sided trailers that have S lock panels are always wood framed to my knowledge. Its a little hard to shoot a staple though an RV siding flange into aluminum tube and expect it to hold. The RV manufacturers are notorius for missing studs or blowing staples clean through the flange even with wood framing. I know of none using conventional RV S lock panels on aluminum framing.
I have seen more than a few new trailers with aluminum siding coming loose, especially with the thin gauge garbage used today, and a few on the PA turnpike being hauled to dealers by transporters with panels flapping in the wind. The only thing keeping it on was trim, molding, and windows.
