How to Choose the Right Cab Chassis Truck
The true measure of a medium duty cab chassis lies in its upfit readiness and Gross Vehicle Weight Rating relative to your specific payload needs. Great choices offer clean Cab-to-Axle dimensions and pre-wired auxiliary switches that save thousands in fabrication costs, whereas mediocre options require extensive frame modifications to accommodate standard service bodies.
Match your Cab-to-Axle measurement strictly to your intended body length; a standard 60-inch measurement fits a 9-foot body perfectly, while an 84-inch measurement is required for 11-foot to 12-foot bodies.
Ignore flashy horsepower numbers and focus on low-end torque and the Power Take-Off provision, which is essential if you plan to run hydraulic equipment like cranes or dump hoists.
Check the frame yield strength measured in PSI; a minimum of 50,000 PSI is standard, but heavy duty applications like towing or concentrated loads demand 80,000 PSI or higher.
Identify your operating environment to choose the right fuel type; diesel dominates for high mileage and heavy towing, but modern gas engines offer lower upfront costs and easier cold weather starts for local urban routes.
