No I am just an fellow RV owner like the rest on here. The OP asked a question comparing these hitches so I am giving my opinion and helping people that do not know there are other options out there besides the standard heavy expensive fifth wheel hitches.
I know you don't have to be perfectly level or perfectly straight but there are significant limitations compared to a cup and ball. I can be way off in both directions and it still just comes on and off the ball with ease because I don't have to drive into or out of the hitch. Some of the places we go this becomes a problem for my friends. This is the real world of off road camping - not paved resorts. It's funny though, anytime I tell people positive feedback about this hitch it causes an argument.
Enjoy folks just my 2 cents and experience with this hitch.
