It's Raining Here!
But I just went out in the driveway. Mine is a dually pickup, not the cab & chassis. I run 235 85/16 and the distance, from outer tire edge to outer tire edge is 92". So if they were putting 88" beds and having a couple inches clearance, that was probably on a C&C truck. There is about a 6 inch difference in those two axles.
