I used the heaters with Oxy cut off & a C.O. Detector for back up.. While in a either a Dome tent or White wall. Never had a beep from detector, but slept toasty. When it's 10 degree's outside. brrrrrrr. I just Might resort to the Hotties, buy big box from Costco heat rate are 8-10 hours. Toss them in hammock.. should work great. Thus I am still exploring the art of swing from the tree's Vs Ground Dweller.
