Bolts are yugoes. Rivets are better and welding is solid.
Shear weight is two pieces fastened together with several methods and each method is tested to there shear point which means until they break?
Shear test.
A 1" steel plate vertical concreted in with a 10"x10" x10" X 1" piece of angle bolted with 1/4" home improvement bolt test at 150' the same piece with solid rivets test at 250',with grade 8 bolts 5000' ,with a solid weld joint 10,000

Thanks guys! Completely different than what I thought, your explanation is very much appreciated!

the ultra high efficiency furnaces like the one in my house with a 3 stage heat exchanger condense that moisutre inside the exchanger and gain a lot of extra heat from it.. its entirely possiuble to build your own high efficiency heat exchanger..

I knew I put in my roof vents for a reason! if I could figure out a practical heat exchanger I would put one in, but propane heating is a winter problem!
I figure if I put in a wood furnace with a propane heater then maybe the fire would help keep the moisture minimal?

There are no rattles (none from the metal studs) and no foam or any sort of thermal break between the studs and the bus walls.
If I had to do it over again I would go with the same gauge metal but probably just a 1" stud and track if there is such a thing. (The track is the bottom and top "stud" that has a different profile to allow the "studs" to snap into place.)
Metal is the way to go....

Good to have you join us with your input! Big fan of your build, and the speed in which you completed it! How many miles would you say you drove and how's that been working out for you? I too like the idea of the elusive 1" stud. Still unsure to what extent I'll stud it up, but I like the idea of using studs for walls, ceiling mounts and possibly cabinetry.

Aaron you should be sponsored (if you arn't already) by Harbor Freight, every time you link a harbor freight buy I book mark it on my "shopping list". Do you know if it comes with a die which supports 1" tube?
