I use a double battery (single load) setup very similar to yours, and I'll take the fuse over the CB any day, but whatever - some people like their breakers. The one tip I will share is to make SURE your ground in the back is fantastic, or everything will get very hot. Drill a hole in something other than the trunk floorpan and the body (I used the wheel well I think) and screw a lead battery terminal in there, and use battery terminal connectors and 4 GA wire at least. The cleaner the install the better, and make sure the battery can't move around and touch the posi lead/wire/terminal on anything in the trunk
