Rbrown0059, My B&W hitch brackets are set all the way down and all the way back. But I have switched out the fifth wheel pin box with the MORryde pin box and I'm not sure if I installed that pin box the same as factory height.I just bought a BW3710. Installing in my 2020 3500 Dually 8ft bed. What hight did you set yours at? Lowest, mid or highest to clear your rails Love your cedar creek that was our first choice buying a montana high country 373RD instead.
