I am camped about 20 miles south on Seligman Arizona with Hull 519, delivered in September. From the beginning it seemed like I lost voltage too fast or the solar didn’t charge much. But it is much worse now. I ran the generator last night and got it to 12.1, dropped to 11.5 off of the generator. This morning I was at 9.1 volts running almost nothing but the heater (40 degrees at night). So I fired up the generator again at 4AM so we could go hunting. Got it to 12.5 and left it with nothing running in full Arizona sun all day. Came back to 10 volts at 2PM. My sister had 13.5 in her Forest River. I find nothing loose or obviously wrong in the battery tray, under the couch or at the panel under the dinette. The panel indicates charging on solar but voltage never gets very high and drops like a rock with no input. Seems to be getting worse, like something is drawing a lot of juice. I am running almost nothing. Is there anything at all that I can check or fix or work around? I can’t stay on the hunt like this.
