Jeff and Austin Mercer built out a Viper red 2006 Sterling truck with a 3,000-gallon steel Specialty B Sales tank and Patriot 3000 pump (Magnum Venus Products). The truck is powered by a Caterpillar C-13 380 hp engine matched with a 10-speed Eaton Fuller transmission. The father-and-son team assembled the truck out in their welding shop, adding top and rear manways, dual 3-inch inlets and 4-inch outlets, three sight glasses and rear work lights. The truck features aluminum wheels, air-ride seat and work lights. The lettering was also done in-house with the Mercers’ laser-cutting machine. Austin is the driver and the truck is used for residential septic service.
