Wow i woke up to some great advice.. i really appreciate it guys..
and yes if my trailer is on its side i have bigger issues then batteries. ha
usage is still under scrutiny by the wife. id like to boondock for sure. we are in texas so i'd like to go out to crystal beach, big bend, etc. i didnt realize the existing batteries were 6 volt. glad i asked.. i thought they were 2 12 volt batteries wired together. thats what i meant when i said i know just enough to be dangerous. i will be purchasing a dual fuel generator for boondocking so i wont be on battery power the whole time. its sounding like 2 6 volt golf batteries will be my best bang for the buck. able to draw them down farther.. also would give me the power i need while i navigate the rv world. any specific brand or model you all suggest?

I'd still like to see you do an energy audit (look at what devices are going to run and how long you want to run them...then add up the watt-hours to determine what size battery bank you need).

But in general terms, what you describe is probably (not for sure) suitable to a pair of golf cart batteries. With the generator, you can top up the batteries each day if needed.

Keep in mind:
- Don't take them below 50% charge as that will quickly wear them out.
- When charging, up to 80-90% charge goes pretty quick but after that the charging slows down. Consider getting a 100w solar panel (it can be portable), so you can fast charge in the morning up to 80-90% with the generator and then the solar panel will slowly fill the rest over the day.
- Being in Texas, if you plan to use air/con, get a generator of at least 3000w (3500-4500w would be even better). Go inverter generator to keep the noise more reasonable.
