I 100% agree! Towing heavy what is the MOST important thing a truck can do??? Drag race??? UH, me thinks controlling the LOAD.
As long as I get down the hill and still have the ability to stop without overheating my brakes I don't expect any more. If the engine braking cannot be overridden by the ABS system excessive braking can lead to a sudden, unexpected and hard to control jacknife. I agree that controlling the load is most important but I don't think that totally relying on engine braking is the best way to achieve that. I would accept the performance of any of the three for my driving. In fact, in the absence of knowing how engine braking or the ABS would react in a jacknife situation I prefer a system that I have more control of.
Jacknifing is actually one of the things tested in the J2807 and all three pass this even with the exhaust brake. Mainly because the ABS system has the ability to brake certain wheels(even the trailer) and apply different brake pressures to each wheel to control it. All while the exhaust brake continues to gently slow you down.
