With a short bed truck and a fifth wheel trailer you should consider a slider hitch. When I bought my first 5th wheel, I bought a manual slider hitch since I had a 2500 short bed. I didn't like it because you had to plan on when you needed to move the hitch back for a tight turn. When I sold my truck for another 2500 short bed truck, I bought a Pullrite Super Glide which moves back and forth automatically as you make turns. It provides piece of mind knowing that you can make a tight turn without hitting the cab of the truck. Much more expensive than a manual slider but worth it in my opinion.
