Thanks for the info. RV has led lights, a must as far as I am concerned. You are right about the parasitic drains, the unit came with an outside radio (located in the rear storage area), even with the radio off the digital display still is on. As I mentioned, I keep the inverter off and yet for some reason the cooling fan still goes on and off as if it is on. I really keep on top of the batteries, checking water levels and keeping them charged. The battery disconnect switch is on and the batteries should be charging by the generator or 30 amp plug but they are not. I would love to turn as many of the parasitic drains off as possible to prolong dry camping time.
