Fifth wheel pin box extension

My old Terry had a square front and the pin was under the nose. I looked into extending the pin box but instead bought a SuperGlide. I have to make a pretty severe U turn (not 90* but close) in my culdesac to back into my driveway. The SuperGlide did its job and I cleared my cab by several inches. The front cap on my Arctic Fox has a bit of a curve to it but is still fairly square as compared to some of the units out there. However, the pin box is forward of the nose and clears the cab by a mile even in the tightest turns.
