    It eems like what is happening, is that the APU doesn't kick in until after the battery is so low that the truck turns everything off, and it does this nearly every hour. This wouldn't be so bad if I didn't have to lift my bed up, and reset the inverter before it kicks back on. I'm very light on electronics, but I want to get a refrigerator. I can't do that if I have no power for hours at a time before i realize that the poweris out again

    Ill be heading to a terminal tomorrow, but I've already told the mechanics about it, and they haven't been able top fix it yet. any clues about what this is and what I should do about it?

    Oh, and this is a 2010 pro star

    What kind of APU? I had the same problem with a TriPac after I had my batteries changed. It turns out there is an adjustment in the controller that sets the turn-on point based on the current battery voltage. If that turn-on adjustment is set too low, your batteries will drain before the APU starts.

    Yes, there is a controller setting that must be adjusted. If your shop has someone that is trained by Tri pac they will know what to do.

    Not sure but I think you have to have specific computer or some such device to plug into the APU to modify it's basic operational settings and thresholds.

    Not so, there are a lot of settings that can be changed through the controller. You just have to know how to do it and which ones to change.
