The SAE J2807 was developed so that tow vehicles would be tested actually towing a load and the test numbers would be relevant to people buying them.
There is no "compliant" aspect other than agreeing to publish performance numbers where a stated load is being hauled or towed. With a passenger vehicle that holds 4 passengers the testing is done with a single driver and no passengers and the 600 lb. load not being present is ignored.
This is very different if a pickup truck is rated to haul 4,000 lbs. in the bed or to tow 13,000 lbs. from its hitch and the testing is done with only a driver in the cab and no load. Big difference in MPG, stopping distances, acceleration times, slalom times, and noise levels.
The first company to agree to following the test standards was Toyota for what it is worth. But all that matters is the actual testing that is done. If Ram does the testing with a 8,000 lb. trailer or 2,000 lb. load in the bed and GM has a 9,000 lb. trailer and 2500 lbs. in the bed then the test results cannot be used.
This type of testing has been done by independent groups including the people at etrailer and Car and Driver magazine - but not a single "truck" publication has bothered to do this. Guess they don't want to upset their advertisers.
