One more vote for a fixed hitch (B&W Companion) with a 6.5' bed. My Rockwood 8289WS has the Revolution, but I do not have it unlocked due to it's incompatibility with the B&W Companion and no desire or need to turn any sharper than I already can.
I can't help but think that if there were not all of these companies marketing products to achieve this magical number (90 degree turn), that nobody would care. I read somewhere recently (probably here in this forum) a post pointing out how you never hear the TT crowd complaining that they can't turn 90.
