Speaking of stability- we have an adams and it does have some side to side movement. The side to side movement comes from the hitch. Where the hitch pin enters the hole its not a high tolerance fit. If you don't disconnect the hitch often you could make the connection permanent with brazing, welding etc. That would take out 96% of the lean/sway/whatever you wanna call it. I was thinking about trying some red loctite first, the high strength stuff should do it. It would be nice if a stiff rubber or urethane bushing was used on some future designs to allow "give" while eliminating that sway.. some bushings like your car has on its suspension joints.
