Ok folks, need a little help here. I've seen lower voltages in the morning then I would expect (12.1 to 11.9). I run two Group 24 RV/marine batteries, new last year, both test good, and charge to 12.68V. I ran an ammeter last night and with everything switched off, I pull 3.98A. The only thing on at that point is the converter, fridge, LP/CO detector and volt meter. 4 amps seems high to me for my resting draw. Does anyone have similar TT resting draw rates?
