@Kolockum, thanks for the input.
Really, 3 days on the one 12v battery? Which forced air do you have. I've read a couple of threads where some people have both a forced air and a Wave 3 for their ATC.
We've ordered a second 12 v battery but we have not heard from ATC about starting our camper so it is not too late to re-think things. We are newbies to campers and have very little experience.
Ah, Winthrop the land of the good snow. I spend most of my time slaying Olympic slush or the Cascade Concrete. But we normally get up to Mazama once a year and ski at Kangaroo Pass / Hairpin Corner. Amazing skiing.
I installed the Atwood Everest II 7900 I believe. But ATC are installing new and more space efficient units. Furnaces are really good at drying out the camper and gear but because our campers are not very well insulated (thermal pack will help a lot) there is a noticeable temperature swing and the furnace will kick on and off a lot. The wave heater helps mitigate this by providing a adjustable steady output of heat. The only down side is it emits CO2 and moisture into the camper so venting is a must. If I had a 8' camper instead of my 6' I would 100% install one.
If you get a furnace (I highly recommend you do) make sure the thermostat is within easy reaching distance of where you are sleeping. It is a lot easier to get out of the sleeping bag if the camper is warm. Or heck it is a small camper and easy to heat and I have been known to crank it to 90 degrees to get the wife out of her sleeping bag.
We do not use much power. Mainly run the furnace for several hours a day (maybe 3 - 4 hours max), 2 led lights and maybe charge a cell phone here and there. Also when cooking dinner the stove will do a very good job of heating the camper.
We get out alot. It'd be fun to meet up with some other WTW skiers!
We should organize a winter rally. (Not to hijack your thread)
