Ok so I changed direction, I bought a ARB 50 quart fridge freezer, it draws .87amps @ 12v and should be adequate for the amount of food I need for two to three days. I am going with four Trojan T-105 batteries to start, I can get them local for $170.00. I will look for a 12v heated throw Incase I need it for sleeping.
I am planning on adding charging from the truck alternator at a later date but will start with a charger that will run off the Honda 2200 inverter gen I have. Any suggestions would be great. In the future I am planning on a Outback VFXR2812A inverter/charger but with the current financial situation that has to wait. I need to figure out the battery wiring, I have 1/0 DLO cable that I need to get connectors for, I do have a hydraulic crimper. Any suggestions on good quality connectors would be great.
