I have a solution for your clearance issue with your 2005 Ford F-250 Super Duty with a 6-3/4 bed. I would recommend a 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret # RP61412. This will change the pivot point of your trailer to give you the clearance you are looking for. The neat thing about this Sidewinder is that it comes with Air-Ride cushioning that absorbs the shock for a smoother ride. If Air-Ride isn't something you are looking for another great option for you would be the # RP61412. Below is the clearance formula to ensure that there will be enough space between your truck cab and trailer when you are executing a 90-degree turn with the 5th Airborne Sidewinder installed.
(A + B) - C = Clearance
A = Distance from center of 5th-wheel hitch jaw to truck cab in inches
B = Length of Sidewinder arm in inches (22")
C = Width of trailer in inches divided by 2
Please note that if you currently have a sliding hitch you would need to leave it locked in the towing position when using a sidewinder.
Typically extending the OEM pin box isn't recommended by manufacturers. It looks like if you did switch to the 1716 you would only gain about 6 inches according to Lipperts dimension chart. Using the above recommended Sidewinder will give you a more desirable gain.
