I am the OP
To answer some of the questions and comments.
I like to dry camp, just got back from Quartzsite, AZ. We spent 8 weeks dry camping at Q.
I currently have 600 Ah on board. thats 4 Trojan T1275 batteries.
I can easily reconfigure my Outback charge controller for use with LiFePO4.
The batteries I am looking at do have BMS. I am thinking of using the StarkPower batteries but there are other options. Stark is running a special on the 100 Ah units at $899 each.
I have looked at the PD charger/converter and it is also the recommended by StarkPower.
As some of you know I do a lot of research before committing to a final solution.
Pin weight reduction on my FW is also an issue that I am addressing.
