Diesels have less engine braking, WAY less, that gas engines as there is no throttle to restrict intake air and make the engine work. I drove several 7.3s and pulled several horse trailers and even tractors on trailers and thought it was all good. Then one day in my 2000 F350 Dually manual trans 4.10 geared truck I went down a downgrade on US 160 eat of Alamosa CO towing three horses in living quarter horse trailer (about 18K pounds) and NOTHING. Brakes got REAL hot. I thought I was going to lose all brakes as I was pushing it way down and all I got was shudder. Downshift only made engine go faster and did nothing to slow me. The grade diminished and I got slowed and stopped. I had thought that truck had good engine braking until I got a few MPH faster with a few more pounds and a little steeper grade. I did get a kit that let me close exhaust damper and it did WAY better. Autos need to TC lock system as RT said to get the full benefit of exh brake. I think you found that grade with that load and surpassed the engine braking capability.
