I added a 12 volt plug to the bed so I can run a fridge/freezer. It’s supposed to hold 40 liters, it’s the biggest one I could find that was not to tall. I’ve also added a hard cover for the bed. When I go shooting on Thursday I’m bringing popsicles.
I ran 10 guage wire and used a 15 amp fuse at the battery. The plug is rated at 20 amps.
