I've got a generator, remember??....and if there's a real emergency, there's a 12v battery in the truck for gosh sakes.
You've got two 12 volt batteries?...what if BOTH fail?!
Holy ****, what then??!!
The fact is, MANY RV folks have been using two 6v batteries for longer than I can remember....and I'm sure we've all heard the countless stories of stranded RV's, right? These boards are full of them....uh huh.
Personally, I've used the golf cart batteries for over 10 years without issue. In fact, they've lasted YEARS longer than any other battery I've ever had.
But the real plus is how much longer they last than even a deep cycle 12v battery when boondocking. They are just awesome.
As always....YMMV.
