I wired an Anderson Plug from the battery to my rear bumper. I am waiting for the 50AMP in line fuse to come. I will have a short stub with and Anderson that connects when in use to an another anderson connector in the battery tray that runs along the frame to the rear bumper
The 50 AMP Fuse will protect when in use, and I simply disconnect when not in use. The first use if for my trailer. It came with an Anderson, but I never used it. It has batteries and solar power. One day I will be camping and the batteries in my trailer will start to go out at night (no Solar), I can then connect it to the truck to keep the fridge and lights going. I likely will connect it when towing . . . . . Just because.

and it compacts down to the size of my cruiser
I'll be in the back row of slickrock campground next to Cdan in his Kimberley Kamper
