You don't want anything with an open flame in there with you ...... if you wish to wake up.

The old trailer/camper heaters that had a convection sytem (no fans) and a heat exchanger (just like home hot ait furnaces) were great, safe and, needing no electric, didn't need batteries.

They also last forever. I'd be prowling around trailer/camper junkyards looking for one of them.

I had a 10.5' truck camper and an 18' travel trailer that both had them (back when).
Kept us warm and comfy through many an upstate NY hunting and icefishing seasons.

Hey NSAQAM, Larry is very "IN", LOL
You also dishonor the 28th division by using the unit patch as an insult.
As for the liar, welcher Bricktop, his day is fast approaching.
Coward trolls won't accept PMs.
How's the phantom "campfire" coming ?
