We at sdtrucksprings.com built this badboy from the ground up. But this aint no ordinary MackCV713, its outfitted with a Self Steering 20k lb. lift axle, Pulltarps electric tarping system, 58,000 lb camal back rears, a 17 foot double swing gate hardox steel body with heating and a monster hydraulic. The cabs an air ride and all leathered out. We build these things several times in a year from the ground up. Most people dont think much of them but dirty ol work trucks, but to us, these are what have helped build America in the past and will do so for the future. We build them, we sell them, we fix them and we respect them. We take pride in our work, like every honest hard working American does. Keep on truckin' boys! ...By the way, this ones now for sale too..
