I'm looking at mounting a 105AH AGM in front of the drawers, with a DC-DC charger and a fuse block. Will install a 12v plug in the wing top on the slider side for the fridge. Also planning to add a gang of plugs in the face of the wing with USB-C, volt meter, USB-A, 12v etc. all run off the setup mounted to the rear face (vehicle forward behind the 2nd row) of the drawers. Will also wire and mount the HAM radio there as well. Thats all a work in progress hopefully before Cruise Moab.
I think I can fit this battery between the drawers and the 2nd row. If not this one, then a s similar form factor even if I have to go down to 40-50ah.
