I shoot 3 gun competitions, and I wanted to build a cart that carried all my guns and Gear. I built it for a 60's era Army cooler so I can use it for tailgating or whatever. Someone can ride in it, and the handle comes off and i have a hitch to pull it with an ATV, riding mower, golf cart etc.
I don't have a pic of the inside of the cooler, but i'll try and get one. I guess originally they came issued with metal organizers inside them, but i don't have those. I picked it up at a garage sale, and painted it.
