While up there we Officially tested the heater buddy.
This was the temps just before bed .

It did well and we also used a fan to blow some warmth to the front of the trailer.
Notice the humidity was good ,,, but if you add some wet boots and jackets inside overnight . It adds humidity.
(Now we did have a window open about an inch for safety and it gets shutdown before we sleep. )
During the day testing))).
At first I put it on the floor and it shutdown itself in 20 mins.
So I placed it next to the open window. Ran fine after that.
Sleeping in our -5° bag , we kept warm all night.
The next morning I noticed frost on all the aluminum trim inside.
Even had a few small icesicles on the rear doors.
Couldn't get the heater buddy to fire up, so we cooked up some coffee and that actually helped warm it up enough to get out of the sleeping bag.
For next winter I'll be seriously thinking about a cubic mini stove.
