I'll look into that for sure!
Now that I'm back in Colorado, have become more familiar with her, and had her winterized I've had time to think about it. Having additional item(s) on board when I already have redundant systems doesn't seem necessary. Tell me if I'm missing something and these are my thoughts:
1. I bought new batteries so that fixed my problem.
2. My bearings in the motor were squealing, especially on start up. I replaced the motor, and now feel confident in the furnace working good.
3. If I'm plugged in I don't need to be worried about draining the house batteries and a 12 volt
ceramic seems to be a good back up even if boondocking. I know it draws on the battery but I can fire up the onboard generator. If its after generator hours and my batteries are low the Mr. buddy catalytic heater would be nice to have.
4. One of my roof units is a Coleman Delta T and it seems to have a heat option. I haven't tried it yet and this would also only work if plugged in or have the generator running.
After typing this out I think I it comes down to if I want to have a true back up the catalytic heater is the way to go. I don't do much cold weather camping but it would of been nice to have a back up on this last trip!
Do most of you just travel with a few small bottles stowed away or do you have a location you can tap into the propane from the inside?
