New RAM short Box and B&W RVK3600 in rear most position

I installed a second set of bed rails in my CCSB F250 to put the pin 52" from the rear window. That's 12" behind the axle. With our 1700 lb pin weight, I can't tell the difference towing. Doing the math, it took about 120 lbs off the front and added it to the rear. No big deal. Not recommending this as it goes against the manufacturer's recommendation but for us, it works. Many welders do this to make room for their welding rigs in the front of the bed.
