Before we downsized to a 1500 and a TT, I had a fifth wheel with the Goose Box. Very smooth ride and hitching/unhitching was quite simple. The airbag and dual shocks take much of the chucking out. I can't say I've had it at 90°, but the camper was close enough to the cab that I didn't want to test it any farther! I know of at least 3 others that saw mine and have since changed out their kingpin setup and are glad they did.
One of the best parts is only having to remove the ball and chain anchors to get full bed access when needed.
