Something to keep in mind about the PullRite Superglide- you must be within 10° of straight to connect/disconnect. If you are not, the hitch has started to slide and will not release by driving forward. To get around this if you get in that situation, you need to remove the pins that attach the hitch head to the base and lift it up, out of the base. I had to do this at the Elkhart Fairgrounds for the rally. It's quite simple, actually.
This next comment is not meant to start a controversy, as I have friends on here with this setup. Please take time to think about the Anderson. It is not approved by most manufacturers of frames. There isn't much metal. The geometry is there in the triangles, but there's something about it that isn't accepted by frame manufacturers. I have a friend with SOB 5th wheel that was told by the RV manufacturer that his warranty was void because he was using it. What saved him was the dealer recommended the hitch and installed it. The RV manufacturer paid for a new hitch and installation to replace the Anderson.
The Curt Crosswing has caught my attention.
