Olympian wave 3 0r 6 heater?

[six5]

Hello all. I just purchased a 2004 baja qwest. I'll be 3+ season camping off grid in colorado with night temps in the teens.

The wave 3 is 12"tall x 10 1/4"wide, it will fit in the cabinet under the sink and I could pull it out on a rail system. BUT I'm not sure if it's enough Btu's AND I have no idea where to mount the bigger 18"T x 13"w wave 6 any ideas.
Thanks for your help, Six5

I actually bought a Olympic wave 6 heater and have officially broken it in. I took the pop up to the high desert and camped for two nights. First night it was freezing in the high 20's low 30's. 6,000 btu's isn't enough btu's to heat the whole trailer under these conditions. So what I did was directed the heater at the bunk and sure enough it worked. kept me comfortable all night long without the power drain or the noise. Second night I used the forced air heater and yes it heated the whole trailer but ran almost all night long and drained the battery. Under less extreme temps I'm sure the wave 6 will be fine.
Never did the CO/propane alarm go off or the fire alarm. I'm happy with its performance.
I just stand it in the middle of the isle and stow it when finished using it.
