Adjusting a Dexter 221-0031-00 Pin Box on Jayco Trailer for Bed Clearance on 2019 GMC Shortbed


Believe this company was acquired by Lippert. Nonetheless, my new to me 2012 Jayco has this pin box as OEM. The prior owner towed with a lifted F250. I have a 2019 GMC 3500HD 6ft 6 in bed no lift. I need to raise the front of the trailer for bed clearance and for level ... so lower the pin box. Can I simply the pin box the equivalent of one hole and simply re-install all six bolts per side?
