I’m thinking I have 3 options here
1. Replaced both batteries which are 2 years old
2. Getting (2) more 12v batteries and parallel all 4 batteries
3. Buying (4) 6v batteries and run them in series
It would be nice to be able to boondock or travel long distance with losing all the food in fridge!
If anyone has any advise for me it would be much appreciated

I went with 3 100ah Lithium batteries with 530 watts of solar and I am fine and never lose power plus lithium will charge in 2 hours from zero plus you can use all the 300ah unlike acid flooded batteries you can only use 50% of the ah,s...But not cheap but they will last for 20 years
