My plan:
Steel frame. The bottom will be a bit beefy with captive springs holding the box to the truck frame. Wall framing will be max 2” tube. Other places will be angle.
Insulation will be 3” xps foam. So, no exposed steel.
Deciding still on mounting of interior. May run small offset steel tabs or wood battens to reduce conduction. Have not decided yet.
I will combat condensation by having no propane on board. Constant ventilation from outside. Dehumidifier running. And as few thermal bridges as I can.
Plus, it does not get cold often where I live. Most concern would be on trips.

I'm not sure that I understand the propane comment. Certainly propane combustion, or pretty much any combustion creates H2O, but this should be vented. Second, just human perspiration and cooking and showering will overwhelm a camper with moisture. Copy the professional builds. You will save yourself a lot of frustration.
