Welcome Aboard!! 🥂👍
My experience...I learned that the TV alternator is the least effective way to charge the AS batteries.
I have never used 6v, Two Interstates 3yrs> 2 Lifeline AGM's 11yrs> 2 Lithiums 1yr.
Even the 200a in our Suburban is marginal at best.
FWIW...we used a 1000w Yamaha genset to keep everything charged in our first AS...23' '63' Safari.
