This Chev Silverado 2500HD Tow Test compares it with the equivalent Ford and Dodge Ram trucks.
All trucks are loaded the same with a trailer and timed – not going uphill – but down using the exhaust brake only. Why? Well if you have ever done, or do, heavy towing, then you will know downhill braking and related vehicle control is extremely important as is avoiding having to constantly use the vehicle brakes to keep speed under control.
Over use of the vehicle brakes will quickly lead to overheating and in extreme cases can result in brake failure and disaster. The general rule in the heavy trucking industry is whatever speed and gear you can travel up the hill is the same speed and gear you use to come down engaging the necessary gear and speed before the descent starts.
The invention of exhaust brakes in a diesel engine certainly made a truckies’ life lot easier, plus saving heaps dollars on truck maintenance, especially brakes. Sure exhaust brakes are noisy but they are for highway use, not urban driving, and can be selected on or off.
