I built my own "house" electrical system for the truck. I detailed it in my build thread. I used a Blue Sea Safety Hub 150/300A switch/MRBF fuse holders with fuses/12 slot ATO fuse block, Slee Accessory Mount, Victron charging components, and custom length battery cables with copper lugs crimped with hydraulic crimpers , and Anderson connectors. I chose Victron because of their good reputation in the maritime community. I could have used Redarc, but the price difference was negligible and I like separate components versus something integrated. Plus I can mix and match the best components should the need arise.
The system has been rock solid. Everything has stayed tight after over a year of daily driving, road trips, and the occasional camping trip. Highly recommended.
