I was thinking about running a heavy 10 gauge wire to power the back 12v. In our 80 series I converted an ARB single outlet to a standard 12v plug and mounted it to the carpet next to the drivers seat. This was an easy access to plug in the fridge and it used up the wire run from the cord to that came with the fridge. This allowed for the shortest wire distance (length) to the battery. We run the Engel MT45 and never had any issues with battery draining to low. We do not stay put for more than a day.
