Thanks everyone. I failed to mention that I have had the camper plugged in to 30 amp shore power while in the barn the whole time. So maybe since the only battery charge level indicator is with the Zamp unit, my problem is not with my solar at all but rather 1) my batteries are not being charged by the shore power and/or 2) there is a pretty good drawn going on. I hope to get down and mess around with it more tomorrow night. I have a friend who is an electrician going to stop past. I did check the Zamp manual but it was not much help. Any more suggestions - send them on. Thanks.
