Seems like a lot of cross currents going on here. Phil has the best perspective. I’ll add one more thing about AGM batteries. Our 2020 Northstar Laredo SC does have a pair of group 31 AGM’s hidden under the cushion of the seating area. They are NOT strapped down because no one gets that off camber or out of level as much as we do. There is a 1″x1″ strip of wood around the battery base that is supposed to hold them to the side, in place. On our recent ARBORGEDDON Adventure both batteries had slid or bounced out of the 1×1 surround, obviously from going downhill at an extreme angle which pulled on the crimp connected wiring enough to open the circuit from the solar panels and allow no power to the camper. I’ve gotten the batts back in position but need a very sturdy tie down to keep them corralled. These are so heavy the tie down needs to keep them from falling out if the camper is upside down, like the pictures of the poor guy and his new black hardcore $150K camper on here.Of course, if the picture is that decimating, batteries are the least of your worries.
