I saw your pics with the machine in the trailer, but now I see the doors were still open, I know what you mean about the weight distribution problem, is yours 10 or 12 K gvw.
As far as dumping these things are great, they legally haul more than a 1 ton masons dump, still should have gotten the 12 FT with the twin pistons though, mine is a big single piston, once out of 30 dumps it wouldn't lift the load which was 3 ft over the sides just shifted some of the weight to the rear and it dumped, with the twins it would dump 2 X's the gvw probably.
those tilt trailers are sweet no more ramps to deal with but for my needs I could handle the ramps for the little use that I require.
