IIRC ideally you want it 2" before the axle, the problem you run into with a short bed is that with the pin so far forward you may not be able to jacknife the trailer while trying to fit into a tight spot - its front corners may hit the rear wall of the cab. They make sliding hitches for that purpose, you tow with them in the forward position for nice stability, but when you have to park you unlock the hitch and slide it back some, this gives you the extra distance between the pin and the cab rear wall to jacknife the trailer if you need it to.
