Here's the first look at the B-81, Ralph did a beautiful job as usual, she sits just right on her metal frame with the proper clearance between the top of the 12.00-24 tires and bottom of the fender. The red cab is a B-81X with standard 158” wheelbase. The orange cab is a B-81 SX with a Sheepscot 26288 Marion dump body on a Mack standard 175” wheelbase.
