I'm not sure which hitch you saw but I use the super glide that has the cam action for moving the hitch back as much as 14" when you're turning. I pull with a 04 Dodge 2500 4 door, short bed and can turn my Wildcat a full 90 deg and still have about 6 inches clear behind the cab. The hitch is 16000 lb. capacity and by just pulling 4 pins I can lift the hitch out and have a clean bed. I bought it on E-bay for $1100 including all the hardware. I think its great. Hope this helps.
