Hey I currently haul chicken and cow manure to my orchard. I wanted to see if I could turn my box into a dump becuase its a real pain in the butt to unload. Its kind of big though. A local mechanic told me could be done just need to dump the bags before. And keep bushings tight. Box is 6.60mts long, 2,30 wide. And 2.50 high. I was thinking of adding a third airlift axle for stability when I unload.
