Although you are ignoring the fact that unvented heaters need to have a window or ceiling vent opened a bit to replenish the oxygen they consume, and to reduce moisture build-up.
There is some heat loss through that opening.

Just depends on your perspective of what is "comfortable" living quarters temps..
The heat loss from one of our awning windows opened 1/4 - 1/2" and our Maxxfan open the same is virtually nothing, and certainly a huge difference over the furnaces heat loss.
Wind is not a problem. I just make sure the awning window chosen to be cracked is not directly into the wind.
I'll agree that comfortable to one is not the same to the other. Our camper is a 21' Escape 5.0 fifth wheel. The body is about 20.5' long, 7' 4" wide and around 6'8" interior. It's all we need.
We use our Weber catalytic heater when the overnight temps get below 40 F, otherwise when the temps are over 40F the Weber is too warm. At about 30 F we kick the furnace in gear to make up any difference. The Weber on low will run all night on one re-fillable 1# tank.
Enjoy,
Perry
