I didn't really gain any help in turning tight with my Andersen ultimate and my bighorn. Hitch moved the ball back 4 inches but with a 1621 pin box you have to put the adapter on so that the pin is in front of the ball or have bed rail interference issues. Trailer ends up same distance behind as with pin right over axle. Pivot point still 4 inches back but pin box length effectively shorter which reduces effectiveness of nose cap cutouts thus cab/trailer interference remains about same.
I couldn't keep my hitch base from slipping occasionally resulting in loud pop. Torqued to 50 ft lbs with trailer weight on hitch. Hitch adapter got damaged twice by dealer using ball on fork lift. Resulted in lock pin binding and adapter having to be replaced second time. Bed of truck starting to deform and lippert 1621hd got trashed from all the weight being carried on two set screws. Ordered and installed B&W hitch, also ordered 5th airborne pin box which I'm still waiting on.
Personally, my advise would be to avoid the Andersen hitch unless you have a really light trailer. Neat idea but not really ready for prime time yet. I totally lost confidence in it, and wold have swapped it out even without the damage it's caused and causing. Can't really comment on the B&W yet as I haven't towed with it yet. Should have approximately 3k of experience though by end of Oct.
