The genny can put our far more power than your batteries can take in...to just run the genny for the big stuff while you're awake and you'll have fully charged batts for the lesser overnight loads.

I agree with posts 5 and 6, except for the time to achieve 100% recharge. My experience is to achieve 100% charge takes the better part of 3 days. I have monitored this on my Trimetric management system. The finishing ampere flow slows down to as low as .01 Amp before completing. This is with a single group 27 deep cycle battery and a Progressive Dynamics converter/charger.
I had a similar experience with a previous 5er with two golf cart 6v batteries, the Trimetric, and slightly larger PD charger/converter. In both cases after boondocking and using the generator for 4/hours a day, we would arrive at a CG with full hookups. Then using CG power, it would take 3 days to complete the charge.
