Furnace power draw
Seems my propane furnace draws about 8amps while blowing. Doesn't seem like much but on/off throughout the night adds up. Are there any options regarding more efficient blower,mods,etc. Mines a single...

I think OLD BIS is really right on this subject...the air moving across the heater transfer system keeps the temp of the burner from not getting far more dangerous for fire potential, so I would NOT slow that main fan down on the heating system. I have had the heater run alot during a very cold trip with just two 12v batteries and yes the draw took the batteries down, but not low enough that the genset would not start.
I found that I had an air flow issue. I found some ducts a bit too long for the run, so I trimmed them to stretch them out. I found the flow to be very low to the furthest points in the TC so I installed an inline blower and some extra duct to supply the back of the TC...I switched this extra fan so I can control the draw during the night when I am asleep and don't need the bathroom warm. But actual use has shown it is always on and I have had very little battery issues even when very cold. So when I add two more batteries, I feel confident that I will be just fine. My system keeps the TC comfy.
