This just might be the flagship truck, or as we call it the "Johnny cash" truck. Basically its a 1979, well some of it. The Transtar II has a Big Cam III Cummins RTO 12513 Spd., Neway air ride, air ride cab, dual exhaust, dual intakes w/dual filters, and dual power windows. Rockwell rears w/ 3.70's. And of course straight exhaust w/ Jake brake. Oh yes a long wheel base w/ 13' of aluminum deck plate, wheel base, lets just say its long enough.
How about a 1975 GMC Astro. A very clean truck with 440,000 miles. Reman by gm 8v71 Detroit @ 333 H.P. RTO 12515 spd 4.10 ratio. This truck is fun to drive.
