Wachs Utility Products has partnered with Knapheide to deliver the ultimate valve maintenance truck—combining maximum storage capacity with exceptional power and versatility.
Step 1: Choose Your Chassis Cab
Begin by ordering your chassis cab vehicle from your preferred dealer, ensuring it meets all federal, state, and local regulations. Wachs Utility Products does not supply the truck chassis cab but offers specifications and recommendations to ensure compatibility. We strongly recommend custom ordering your vehicle to meet the following minimum specifications:
- 19,500 GVRW minimum rating
- 84-inch (213.4 cm) cab-to-axle length
- OEM high-output 300-amp alternator or dual alternator arrangement (to support the service body’s 200-amp power inverter and the truck’s electrical load)
- OEM rearview camera with prep kit
Once your truck is ordered, drop-ship it to Knapheide using these site codes:
Step 2: Service Body Installation
After delivery, Knapheide will upfit your truck with the custom service body, including the Wachs Service Body Skid. Available with gasoline or diesel power (matching the truck’s engine type), the Service Body Skid comes preassembled by Wachs, complete with all mechanical, fluid, and electrical connections. The result is a turnkey valve maintenance truck ready for action.
Choose from a variety of options to meet your operational needs. The combination of Knapheide’s expertly customized service body and the Wachs Service Body Skid creates the most advanced and efficient valve maintenance truck in the industry.
