It's a pretty simple system, Blue Seas Systems make a product called a battery link, this is connected to the positive post on the trucks battery, this has to be fused, they also make cool fuses that mount on the battery . This goes to the battery link, the links output will go to your house battery positive post. The negative on your house battery goes to the frame Of the truck (ground) these wires should be at least 4 ga, 2 ga would be better. What this does is when you start your truck the link sences the "charge" from the alt. It's connects the house batt to the truck batt. When you turn the truck off it disconnects the house batt, so you don't have to worry about a dead start batt. Then your inverter connects plus and negative to the house batt. I would recommend a pure sine wave inverter which produces the same electricity that is in a house, a square wave inverter can damage chargers and electronics, a good place to buy the inverter is a online co called Don Rowe Inverters. To mount the house batt. Marine battery boxes or tray will secure it. Boom! Your finished. Any questions give me a shout. You can find the link on amazon for $100 , the hardware, fuse holders , lugs , West Marine or Defender catalog, do not skimp on the wire gauge. The fuse at truck batt 75A. Fuse size going to inverter will depend on the size of the inverter. If you want solar also the solar panel will go to a controller, the regulates the charge coming from the panel and dosent let the batt to backfeed back to the panel a night. The output of the controller goes to the house battery, don't waste your money on a small panel, an 85 W panel will give you around an 7A charge, a 125W panel will give you a 10A charge.
