2" in front, and here is why.

"Expert Reply:
When installing a fifth wheel hitch on a truck, the king pin will be centered over the rear axle or slightly forward of the rear axle. It will depend on the year, make, and model of vehicle and the size of the truck bed on where you will need to locate the fifth wheel hitch on your truck.
The reason the fifth wheel hitch is located at the rear axle or forward of the rear axle is that the pin weight of the fifth wheel is now pressing down between the cab and the rear axle, which will distribute the weight of the fifth wheel correctly over the rear axle of the truck, instead of behind the trucks wheelbase. This will allow the truck to carry a greater amount of weight and keeps the weight of the fifth wheel from raising the front of the truck so much that it causes handling and tire wear issues.
It also makes the fifth wheel easier to maneuver, like backing up or angle into parking spaces, since the hitch is closer to the turning wheels of the truck. It will also allow the fifth wheel to ride smoother."
Canned answer.
The reality is VERY LITTLE weight will transfer to or from the front axle with a 5er. With WELL over 5K pin with my pin about 2" forward I only add a bit over 100#.
With a lighter TV 4" behind axle may have SOME adverse effect but with these newer trucks with over 5K front axle weight taking a couple hundred pounds off the front axle will not be a problem. Ask B&W why their fixed hitches are able to be set 4" behind if it was not safe they would not make it possible.
A little knowledge and common sense goes a long ways.
I used to be in the NO WAY over or behind axle center group but I have seen the light in SOME conditions.
