Thanks for the info Dcoy. Do you have any suggested resources for installation of Heatsource heater to heat RTT installed on top of LC?
If the RTT has an annex under it, put the Mr Buddy down there, and let the heat rise up into the tent without it risking burning thru anything (support it near the ladder), then vent a window in the tent too. The heat will rise up and warm the wife up, then go out the window and not kill you.
