Anyone having any tips on wiring up a house battery to the bed of my tundra? The only thing it will be powering is my Edgestar, no lighting, laptops or anything else. Probably be 3-4 days between any significant driving to re-charge. I've had the Fridge run for 2 days in mild weather off the starting battery w/ no problems but I want to make it independent so there are no surprises.
Thanks

Either of the following types work well in our applications. Of the two I use the ISO-Power because I've found the power-pole connectors prevent "Rum soaked stupidity" from allowing you to connect something backwards...get expensive! Also it allows easy expansion as your power needs go up. I tend to stay away from the "Diode"type isolators though, they will drop .7 volts across the diode before getting to your second battery. Add voltage loss in the wiring (most people wire with too small a gauge), and over time it never seems as though the second battery never gets charged.

Good info. Thanks. I've been known to suffer from RSS syndrome.
