Ive seen a 12 ft. bed made to dump with an electric hydraulic set up but they are 2500.00 The pto for the M215 is rare as hens teeth. Been there, done that. Also the channel on the cargo beds are too lite to hold up well under heavy loads. They need reinforcement. It isnt a double acting tailgate either, but for occassional use its O.K. I have had many dumps, so I know the problems with them . I am working on a military bed now that is rusted out so bad the hinges broke off. But I will restore it. Lots of 5 ton dumps up for sale on G.L. but too far away.
