Heavy-duty semi-truck transporting massive industrial machinery on rural highway

Richard Berst operates this 1999 Peterbilt 379 hauling oversize/overweight freight. About a year after he bought the unit, he stretched the frame to 330 inches and added a lift axle. A half-year on, Berst repainted the truck from tan to the purple shown here.

It's powered by a 550-hp Cat 3406E.
