Thank you! I learned the critical vocabulary word I was looking for-"studs", I have spent weeks trying to figure out why I couldn't find what I was looking for now I have found a lot of nice leads. Perhaps the guy you were talking about was "FixItWithMike" on youtube, you
After using this same search term with google via "site:skoolie studs", I then re-discovered The Great White Buffalo Thread
. Where he does all his framing with steel studs which starts on page 4.
I also came across some funny threads
where Nat condemned the poster for not using the search function properly. However I did find some good stuff which I wanted to copy pasta here.

It would be more apt to think of metal studs as formed sheet metal channels (since that's what they are) and are structurally strong in specific ways that force you to construct your interior parts on a bus in a specific way that isn't always optimal.
The 2x4 (and smaller) wood construction that you see in skoolies is more versatile to constructing the shapes and parts that need to fit than the steel studs simply because they can be combined and used in nearly any orientation.
After evaluating steel stud, 2x4, plywood, and other media, I personally settled on 1"x1"x0.065" thick cold roll square tubing. With a welder I can quickly assemble small frame pieces and attach mounting flanges cut from 1/8" flat bar stock.
I can also use nut-serts in the square tubing, which let me build large assemblies that can be deconstructed and reassembled for installation, maintenance, and plain changing my mind about something.
Per linear foot, 1" square steel tubing has a much higher modulus of elasticity, lower weight, and takes up less space than both wood or sheet steel box (steel stud) construction.
To go even further in optimization, a panel formed from fiberglass or sheetmetal would probably be stronger in-situ, but the specialized construction techniques, and planning requirements for building those components is far more effort than bolting or welding together some square tubing.
One of my favorite things I learned from this quote is regarding "nutserts
", I will look into these later and possibly report back into this thread.

not that school busses arent clangy and rattley already stock..
YES! I wanted to bring this matter up, would it be practical to put in some cheap foam
or rubber between the metal and the floor/walls to dampen some rattling and sound? Would anyone have experience with something like this? Conceptually it makes sense to me, it may also increase insulation values somewhat? Maybe.
This now brings more questions to mind, but makes me think the following. Maybe I should do cabinets with the studs and appliances with steel tubing? Or maybe I'll do everything with steel tubing. I guess I should take a welding class first and decide how long until I am capable of welding together the steel tubing as desired. Anyway at this point I'm rambling so I'll shut myself down here. Thanks again all, your input is awesome.
