Ok Guys this is a bolt on bed. I made it for my 99 f250. It will fit a 99 -2004 f250 and f350 chassis. This is made for a single rear wheel truck. Im unsure if it will fit a dually. I built it for about $3000.00 and it keep the trailer hitch operational and that was why it does not have a dove tail. Here is a picture of it. We run 3 trimmers 2 blowers, 1 push mower 1 5 gallon gas, 1 5 gallon mix, 1 36 and 1 48 walkbehinds. I will also sell the truck and body if someone is interested as we need a larger dump truck to replace it. I would like to get $3000.00 for it.
