Been thinking about trying this for a few winters now and have finally gotten around to gathering what I will probably need. I already fish out of a cabelas 6x8 popup with a buddy heater (won't use at night). Picked up a hunting cot from cabelas, army surplus sleeping bag, a decent used gas generator, and a nice ceramic fan heater. Generator would be placed downwind of course.
Propane camp stove for the vittles, and camp toilet for the obvious.
Anybody else overnight in their tent?
