Boondocking means solar or generator recharging. I run my rv pretty much electrically.
I could go on and on about why Li don't suit me.
You have a good system that anyone who doesn't have cold weather issues would be happy with.
As to longevity, my first battery bank lasted 9 years.
I think Li are extremely overpriced as current battery prices are $137 per KWH for li. So why are the makers charging so much for a 1.2 kwh battery?
