Red River brand dump truck box. I had the intentions of putting it on a truck, but the truck I had, wasn't suitable for it and ended up finding a dump truck all ready to go. Got this box at a sale and it was suppose to be ready to go...well it didn't have the correct cylinder with it. So it will need a trunnion style cylinder or make mounts for the box and use the one that it came with. 15' 8" at the top and 16' 3" at the bottom. Good floor, just a couple dents in it. Has a rock/coal door. $1500 cash. Will load. Calls in the evening(no texting)
