I was in a similar situation about 3.5 yrs ago.  I have a Dodge 3500 and occasionally towed a 30' gooseneck trailer (which wasn't mine).   I built my bed rack with keeping it easily removable in mind but honestly once it's on and situated I have never wanted to take it off and never have.  I found other ways to get around the gooseneck issue (borrowed a friends truck a few times, and now have hay delivered for a small fee) and that trailer isn't even in the picture anymore.   
Figure out what your top 3 uses for the truck are and the order of their priority and build to that. Just about any setup can be undone in a few hours so it'll all depend on how badly you want to tow that trailer.
