The “Rock On Trike”In March 2008 a machine like no other started to take shape in the Rock On Repair Shop. A wild and crazy idea was starting to be taken seriously. The Rock On Trike started its life out as a 1988 Kenworth dump truck, stripped of parts and neglected through out its usage, there wasn’t much left for a work truck.. The cab, dump box, engine, axles and related components were removed. The frame was modified and strengthened for its new design. Key features to keep were air ride, air brakes and to keep the old hood. The Cummin’s 350 Big Cam IV engine boast a whopping 400hp. The trike was built primarily to promote awareness to our brave troops and veterans who have served us and are serving us now.
