Question for other Ford owners with SB and B&W Hitch

[lwg]

Got a quick question for other late model (2011+) Ford short bed owners who run the B&W hitch. Which holes do you have the hitch setup in? Mine is at the lowest spot in the middle, I think. When I weighed recently I noticed that my steer axle was about 100 lbs lighter with the Redwood hooked up. Thinking I need to move the hitch forward one set of holes,but want to make sure I still have clearance with the cab.
