For what it's worth, these are the true deep cycle Group 31 12V AGM batteries that we use two-of in our RV. They're used in boats a lot, have a capacity of 115 AH each, weigh around 72 lbs. each, and are expensive. But it bought them instead of Lifeline because their recommned float voltage is what the stock RV converter delivers, and I didn't want to have to change the converter: https://www.fullriverbattery.com/product/dc115-12/
Just installed 2 Duracell 31DTMAGM deep cycle from Sams in a 2019 Navion View ($404.00 for both). Had 5 modifications.
1-added 2x4 blocking 22” long to raise the batteries above the angled support.
2-cut off angle on each end of the battery compartment by drilling end of each angle that allowed a reciprocating saw a slot to cut 1” off each angle and added and screwed a 3/4” angle on the cut off angle to allow a flat surface against each battery.
3-replaced 3 each 12” cables with 16” cables.
4-cut off the 2 fuse connection bolts about 5/8”.
5-replaced the battery 2-9” tie down bolts with 2-10 1/2”- 1/4” all thread bolts.
Dropped one battery in compartment and slid to one end. Pulled off the gasket surrounding the open end of the compartment. Had just enough room to drop other battery in the compartment. Installed all the cables then the tie downs. Changed the solar/battery charger to AGM. 2 hours picking up battery, new cables, new angle and self tapping screws.
4 hours removing old sorry NAPA 24’s, full replacement and hooking up shore power to charge batteries. Will be replacing 1000w inverter with 2000w inverter so my wife can have her 5 am coffee without cutting on generator and waking me. Everybody is happy.
