Your Wagonmaster heater may kill you

We've regularly camped in -20C temps and felt it was reasonably warm in the trailer. That included using a PC fan to move the heated air from the furnace though.

At -13°C, I found it kinda cold in my 4500. Hopefully the fan helps.

Did you factor in the mammilian heat produced in your calculations?

Roy, you camp with two large dogs. That's cheating.

The BTU calculators are imperfect at best. I tried 3 different ones. Using the same numbers, all 3 came up with different BTU requirements. None of the calculators requested a measurement for "mammalian surface area."

in my pet grooming truck, i have found the wind to be a significant factor. High winds can suck the heat out. Parking in the sun is hotter than parking in the shade.
