I made the plunge over the holiday for auxiliary batteries. I purchased an isolator and 150 amp breaker from Espar of Michigan and installed them under the driver seat. I used 4 gauge wire. I ran the wire to 2 cheap deep cycle batteries (1 form Walmart and 1 from AutoZone) under the passenger seat with each in its own battery box with no lid.
I just got my first load from Grand Prairie, TX to Tucson yesterday. That charged everything up nicely.
The main reason for the aux batteries is my Espar D2 and my TruckFridge cooler. My 2 cheap batteries should have no problem keeping those 2 things running for me. I got tired of setting my alarm for 2 am to wake up and run the van to charge the main battery so I wouldn't need a jump in the morning. Now I should be able to sleep all night.
I wanted AGM batteries, but Turtle scared me with all the crap about alarms and discharging and all. I'll just keep buying the cheap batteries and not worry about his concerns.
