First of all, let me introduce myself. I'm Jeff from NW Wisconsin and West Central Georgia.Yep, a snowbird. I make at least 2 trips per year and camp on and off the rest of the year. I "tented" until ...

Is this the battery you wish to use?
There is an approximate way to get amp-hours from reserve capacity.
In this case, it works out to about 85 amp-hours. But since only 20% should be used, from a Marine "deep cycle", that means only 17 amp-hours capacity per battery. With 4 wired in a balanced manner that suggests a total usable capacity of only 68 amp-hour.
To put this in perspective, my coffee maker uses about 6 amp-hours to brew one pot. The fridge, with a 2:3 duty cycle, running on 120 volts would consume about 21 amp-hours in one hour.
I'm not saying you can't use Marine jars. I did that successfully for over 9 years. But I had 875 amp-hours of batteries in two banks and a modest solar charging system to maintain them.
