2003 Ford E-350 Box Truck 140k miles! Lift Gate

We have a beautiful example of a ford econoline that was converted into a box truck. There is a lift gate that will hold at least a ton of whatever you need to haul. The rear door has a brand new latching system that operates like butter. Brand new rear tires with 1000 miles on them. The box dimensions are 7 feet tall by 12 feet long by 7 feet wide. Heat works and A/C blows freezing cold. Radio works well. For the bad, a towing company mangled the rear bumper you can see it in the pictures. The truck isn’t beautiful but it is a workhorse. We have used it for a year but are realizing there is an easier way for us to do what we are doing. $5000 obo willing to negotiate price. We figured out a better system that would work a lot better with a truck and trailer. So, I’m open to trades or partial trades for a decent truck and trailer. The trailer would have to have ramp access and be at least 7 feet tall by 12 feet long. 7 feet wide is a plus. We can work out partial trades for a truck or a trailer.
