I have a 2001 Isuzu NPR dump truck / maintenance truck for sale. It has a 16 foot bed with 4 foot sides on it with a combo gate on the back that will swing to dump and fold to load equipment on the truck. It also has gates on each sides at different parts of the bed so that pallets of material can be loaded on to the bed of the truck. 147k miles, gas engine. New tires all the way around. $9,900.00. Not many trucks out there with this kind of bed. I will try and add pictures this weekend.
