Fuel Economy While Towing
Fuel economy varies greatly depending on engine choice and trailer weight.
The Duramax diesel provides the best fuel efficiency during heavy towing.
Factors That Affect Towing Capacity
Several factors influence the maximum towing capability of your truck.
Cab Configuration
Regular Cab models generally have the highest towing ratings because they weigh less than Extended Cab or Crew Cab models.
Drivetrain
Two-wheel-drive trucks often tow slightly more than four-wheel-drive versions due to lower vehicle weight.
Axle Ratio
Higher numerical axle ratios such as 4.10:1 improve towing performance compared to 3.73:1 by providing more torque multiplication.
Trailer Equipment
Adding trailer brakes, a weight-distribution hitch, and sway control can improve towing stability and safety, though they do not increase the truck’s official towing capacity.
