6.7L Cummins Forum

Anyone heard of the new SAE J2807 Towing Standard on the Horizon? Should make it easier for us Truck Owners to compare trucks if everyone test and reports using the same criteria.

This new standard will measure a vehicles towing performance based on several criteria using a standard test trailer.

1) Maintaining speed on a specified grade
2) Timed acceleration on level terrain
3) Timed acceleration up a 12% grade
4) Response to trailer sway
5) Braking characteristics at Gross Combined Weight Rating (GCW)
6) Hitch receiver structure and strength

The example that I've seen and gives you an idea of what to expect when you apply these new standards just happens to be from Toyota when they put the 2011 Tundra through the test. The results were towing capacities dropping 400lbs, 500lbs and 1,100lbs for various models of the Tundra compared to previously published capacities.

Kudos to Toyota for stepping up to the plate and having the balls to certify the Tundra against the new standards. Unfortunately the rest of the manufacturers will probably drag their feet until 2013, imagine that.
