Thanks for the comment on the Rig. For the the dual battery system, it took quite a bit of researching time to figure out what I wanted, but once I decided was relatively easy to install, and blended well with the engine compartment and dash. Biggest decisions were the relay box and how to connect the 2 batteries in a way that doesn't interfere with starter battery and electronics of vehicle. I opted for CTEK250 DC/DC charger vs direct switchable link as isolates the house battery and the charger maintains it. I can always jump off the house battery with short jumper cable if ever needed. I went with a Universal Offroad Waterproof Cooper Bussmann Off Road Fuse Box Relay Panel assembled and sold by
bodoke0326 on ebay for $129. This is a very well build box and fit easily in the engine compartment. I ran relays from it to my dash for LED/ditch lights and the ham radio. Im very happy with it. I ca ndig out the wiring diagram if interested.
I see you're in NC as well. I recently moved to Southport area as I just retired. My 4 Runner still in Maine but will be bringing down this Spring for some 4running around. Where do you go?
