Need new batteries!

2010 rockwood ss 2604. Time-for new batterie
Present batteries are 2 6volt duracel pro golf cart 20 ah cap 230 120min @75am don’t I installed them in 3/2017 last season they were all but done. Would run furnace and such but not the slide out and had trouble with awning most times. This year winterizing they will not charge.
I’m retired not a lot of disposable income. So can’t go crazy. Definitely can’t afford to redue my system. Even if I could don’t think it’s something I could do myself.
So do i do 12volt do I do 2 6volt again. Golf cart or something else. IS 12 volt golf cart an option
Most of our camping is boondocking . Mostly weekend twice a year 4 days always have 2 Honda 2000 i companion with us

Price on LiFePo4 batteries has come down so much I would give them serious consideration. Many advantages to them, no maintenance, light weight, lots more available AH etc. A small portable charger charger might be needed to top it off.

Not to mention the LiFePo4 batteries will last 3-5 times the average lifespan od lead acid batteries.

And you'll get a LOT more usable AHs, so in the morning after a night of furnace use, you will probably not have dead batteries.

I always carry a charger. Also. My Honda generator/ inverter what ever it is has a built in charging port that you plug a T shaped plug into with alligator clips on the other end.
What size lifepo4 would I need. I know nothing about them. Even what I read confuses me. I can’t spend $900 on batteries. I’m at $200 range

The 12-volt port on the Honda generator will require hours and hours to charge batteries. Plug the trailer into the 120-volt outlet and let the converter in the trailer charge the batteries. It will take a lot less time.

There are LiFePo4 batteries, 12-volt 100 aH which are near your price range. I'd opt for those.

P.S. - We are all on a fixed income. Problem is, mine is fixed too low.

That was my next question. Getting thru the night this time of year and in October .
Also can you add another battery at a later date. Or do they need to be matched? Like a lead battery.
I may see if I can swing a 150ah instead.

Make sure it has a 100 amp BMS. As in current drain is rated for 100 amps.
Blue tooth connectivity is a huge plus, it would eliminate the need for a shunt monitor.
