Yeah, a little self contained unit would work fine and since the military ones looked like an afterthought, even the boxy aftermarket heaters look like they belong there, lol. One of the little Mojave heaters might not be able to keep up with the air leaks around the doors and windows but maybe one of the larger Vintage Air or Summit Racing heaters would work. I'm sure you have seen the guys over on SS using the HMMWV RedBall heat and A/C units, which would be nice, but are pricey.
