Its been awhile but,,, I think when lund set them boats up at the factory with 24 volt trollers, and 2 batts the batterys were turned a 1/4 in the box...They might have been group 24s though. The batts in my lund are turned and to lift them in and out you almost have to stand them on end to get under the hinged door lip in your first pic. Sorry I didn't see your first post sooner.
