Background info first. 2017 XLite 21RBS. Came with one battery in a plastic case on the cross mount area of the tongue. Upon close inspection, the case is just held down with a cheap strap and can slide and jiggle around a bit while going down the road. My bad for not addressing this earlier, this our 3rd season. Come to think of it, addressing it now in the 3rd season is pretty good for me
. My normal would probly be about 5. We rarely dry camp, but are considering doing more of it. Sooooooo, that leads me to your suggestions. I have no desire to get involved in 6V golf cart batteries. Seems like overkill for what my needs are. So I’m thinking 2 really good low maintenance true deep cycle 12V’s with lots of ampere hour ratings, in parallel, in one nice case that holds both in the stock location on the tongue rack.
Who you got? Both batteries and case. Thanks.
