Why are some people's batteries dying after one night, or especially halfway through the night?
Everything is relative.
Size of the heated space is important, as is the efficiency of the insulation.
Newer units "should" be insulated better but with everybody cutting costs everywhere possible these days maybe not; the OEM batteries might not be good ones either.
Then there is paying attention to how fully they are charged before going into boondocks mode.
Fully charged, my little furnace in the 28" C will keep a fairly comfortable 65 all night with a 35 degree low......but the batteries are low enough the following morning that they barely turn the generator over. Once or twice I've had to start the engine for a few minutes first.
P.S. I just found out in the past couple of days that the cab of my C has basically no insulation at all. Even with an outside shade on the windows, it stays really hot at that end. I am now using the "privacy" curtains for a thermal barrier to the cab. I assume that doing that when it's cold would save a bit on heating too.
Also true. Mine is a 26 ft box, no slides. Maybe older units are a bit more insulated? But the furnace fan runs practically all night. Runs about 15 min, off about 20, repeat.
Not saying anyone is right or wrong, it's just so drastically different that I thought it odd. And wondered if someone had an explanation
