Yup, forgot about the need to rotate. I have a Reese Revolution hitch on my Rockwood, but chose to continue using my Superglide instead. There's no need for a capture plate, but there's a wedge bolted directly onto the pinbox. The wedge actually contacts the back of the king pin, so I was forced to cut the top of the tripod cup away. I just went out and measured: the cup has been cut back to 2 7/8", and the oak disk in the bottom is 7/8" high, so I have 2" of cup depth remaining. It works as well now as it did with my previous trailer before I made the cut.
The suggestion others have made to use the Strong Arm system is a good one, but there comes a point where I want to stop throwing money into the pit.
