I want to save pellet delivery charges by being able to haul a ton of pellets at a time, and was hoping someone could help me RE my utility trailer capacity. It's homemade 4' X 8', mounted on what looks like a pickup truck transaxle. It has 3 leaf springs on R 14 185 tires, and the welds and decking seems sound. The bed tilts where the stem post meets the axle, so I'm guessing where the hitch pin attaches the stem to the axle is the weak point. I'm going to replace the old round steel stem post (which is bent and makes it 'crab' down the road) w/ some stouter new rectangular steel. Short of loading it up and see if it breaks, anyone have any thoughts ?
