New to 5th wheel. Question on slider/pin for crew cab.

Anyone have any experience with this? Looking for pros/cons on the Automatic slider- Manual slider - kingpin concept. Thanks guys!

A 5th wheel trailer and the 1500 5' 8" crew cab bed is a rare combo. I would 1-800 the sidewinder mfg for their input if the sidewinder box will work for that very short bed. Even with the pin located zero over the trucks rear axle the pin box may still contact the tail gate. Give them a call.
