To answer the OP, the only concern, and it seems that one on here had an issue having enough travel on his landing gear to get high enough to get off the ball, and then enough to get low enough to get level for camping. It was first that I have heard of someone having that problem. I have no issues in doing so with my Andersen.
I am a bit nose high, but that was the case with my previous hitch also, nothing to do with the hitch, but the height of my truck, and fifth wheel .In order to have adequate clearance with the bedrails, I'm a little high, and not a problem for me. The Andersen has adjustments same as any other hitch. Your fifth wheel pinbox will also have adjustments. Its going to depend on the truck ,and fifth wheel combination for most of your questions.
I can say I having no turning nor backing problems with the Andersen, and my truck is a 3500 Ram short bed. A friend with the Andersen ,and a short bed Superduty also has no issues with any of your questions. But as said its going to be the combination of fifth wheel ,and truck that determines those questions.
