On two AGM batteries that are what, 200 A-hrs each at a 20 hr rate? I think that you're going to be an unhappy camper if you plan on running these things on battery power alone.

May I recommend that you buy yourself a kill-a-watt, measure the actual A-hr draw of your appliances while in operation, account for duty cycle (Fridge runs more in August -- can be helped with ice blocks), figure out how long you are going to go between recharges, and buy and read the book that I referenced up-thread? I don't have my calcs handy, but I needed way more battery capacity than that.....

BigD, Sound advice, thank you. As for going straight to the batteries with the charger, that was told to me by the tech at Promariner when I called for advice. But i'll double check... I do that allot.

P-Dogg, I know I am cutting it close. I have done the calculations and will probably do the math again to make sure. We are doing weekends on the hook, not much longer than that. I will probably wind up getting a good battery monitor, like the Balmar Smartgauge so I will know where i'm at.
If all else fails and amp hours get tight I can always fall back on the Yeti :P
