I'll look into adding more batteries. Is there a specific brand that I should look for? Do you think going with a sealed battery will make a difference? Should I look into 3 12volt batteries or 3 6volt batteries? Thanks

#1: "Adding" or "replacing"? Adding would mean another one or two 12V, this will not be cheap and you won't have a lot to choose from. If money is a problem, get the cheapest that says "deep cycle". If you can spend more, discard the first one and get a pair of decent 6V or 12V.

#2: No. Not for low currents like furnace and fridge.

#3: Very energy-savvy user needs at least 200 AH bank for 2-3 days with no charging.
Meaning 2*100 AH @12V, or 2*225 AH @6V.

3*6V is IMPOSSIBLE, and tells me that you should read some more on electricity basics before you blow yourself up to kingdom come.

#3.1: Charging on dry camp is neither difficult nor expensive. Small $200-300 solar - even a portable one - will make a world of difference for somebody with moderate energy draw on a 2-3 days stay.

I didn't want to spend any more money on it, so I went with the cheapest option = Walmart. One day I will get a pair of 6V or 12V, and I did realize I shouldn't have said 3 6V but 2 or 4 (probably no space on the A-Frame for one). I will also consider a solar charger. What brand would you suggest? Thanks
