Switching from 12 volt to 6 volt batteries
After our third time out dry camping with our new travel trailer, we started running into battery bank issues. Our first two times out, we had no issues at all with running down our battery bank overn...

You're gonna get a lot of opinions on this one. I like 6v cause you have a better chance of getting a true deep cycle battery with a 6v. It seems to me you can get 235 amp hours from 140 pounds of battery. With 12v you can get 200 amp hours but I think it'll be a few pounds heavier. There are true 12v deep cycle batteries are out there but they're not as easy to find. I'd never buy a 12v "deep cycle" from a local vendor unless they only sell batteries. Trojan are great. I think Deka's are great. Deka's are marketed under the Duracell name also. Duracell batteries are marketed thru various vendors, Batteries Plus Bulbs is the one I got mine from. Thinking I'm two years into them and still perfect. You'll need some kind of recharging ability in your coach if you plan to continue boon docking. I recommend as stout solar set up. I have yet to need to fire up my generator and I use what ever I want, whenever I want. I run 4-6v batteries.
Now that I've come to my senses and I'm not going to triple the capacity with two 6 volt batteries, this is looking less attractive... But I do believe you can pretty safely discharge the 6 volts down to 20%, right? Which, if so, would mean I effectively have much more than what it would look like on paper.
I've been using a generator for a few hours a day, which has worked great. Eventually we'll be adding some additional solar, but that'll probably wait until next year.
