Couple things: Slope that front triangle for a little better aerodynamics.
No matter how much insulation you have you still need something to heat it.
Another aspect for comfort is humidity.
In terms of thickness, you don't need 4" of foam. The limiting factor is how much air exchange you'll need for ventilation so there's diminishing returns for insulation.

My version of a build would use a fiberglass pickup bed tonneau as the roof, but canvas walls since insulation from the cold is not an issue in west Texas. For us 4 foot walls, with a 2 foot cloth pop up would be fine.

AA battery? You’ll need a 12 volt source to run either a propane or diesel heater. You can find those fans in 12 volt.IrrationalExhuberous wrote:Pmullen503 wrote:You can compensate with a larger heater but you still have to ventilate.
Of course, I was going to just cut two holes in either ends and slap dryer vent covers on them with a computer case fan in the midsection wired to a AA battery switch glued to the wall. I feel that should manage O2 just fine and CO so long as I'm not running a propane stove more than few minutes.
I'm hoping I can maintain comfortable residential temperatures with those open with fans off or on low, paired with a small RV heater, for at least 3 nights between refueling.
edit:
open question is where I place the intake vs the exhaust relative to the heater vent and return. probably place both the intake and return rather close together near where my gear corner is and have the heater vent point towards the bedside floor and the outside vent the furthest corner by the bed?
