Good thoughts jerry. I really wasn't sure if i would be better off to let the doors have more room to do what they want, and remember to close when it's on the flats. Or if different amounts of restricting the doors could cause something like a high-center while dumping or jam when closing? I really don't know enough about operating different types of dump trucks yet.

I did learn that the original hitch for these uses a 1/2" OD bushing that the trailer rides on for yaw, over a smaller vertical pin attached to the roll axis of tractor. Also original setup has WAY MORE travel in roll articulation than i had expected.
