I've been trying to find a good location for an aux battery for awhile now, but the engine bay is pretty tight. I wanted a deep cycle in the engine bay and not an AGM inside the cab too. I ended up buying a couple battery trays from the junkyard from various cars and making up a mount, also moved a couple sensors and cleared an area behind the airbox for the 2nd battery. This won't work for vehicles 98+ with ABS junk in this area.
I looked at about 25 different batteries and ended up getting a Duralast 24MD-DL Marine Deep Cycle and it fits perfectly. The battery was $87 from Autozone and the dual battery isolator kit with wiring was $40 on ebay, so overall a pretty solid setup for under $150 and has been running a fridge constantly for a month with normal driving between. I might upgrade the isolator to a Redarc for the jumpstart/winch link function.
This is just a post for those who may have been going through the same issue or trying to find the best place for their aux battery, I personally think this is the best location.
