We recently took an 8 week trip out west and spent approx. 2 weeks in the Quartzsite & Lake Havasue areas on BLM land.
In was quite chilly at night necessitating heat. We supplemented our furnace with the Mr. Heater Buddy. It worked great.
In our truck camper, we found a perfect place to use it! We lowered our oven door and placed it on that.
It was off the floor, in a spot made for heat. It functioned like a little wood stove, as we could snuggle up to it and warm our hands.
