We have the wonderful Bendix air disc brakes on all 5 axles which provides much peace of mind, as you may imagine. But I hear you on the Jake Brake being dangerous in wet or snowy/icy conditions. So it will be great to have that trailer axle holding us back with much less chance of a jack-knife. We also have the new prototype 2017 Cummins ISX installed. The engine disengages from the drivetrain while descending a grade to save fuel. So instead of doing say 1800 rpm downhill while engaged, it will be doing 600 rpm and be disengaged, so it wont hold the truck back and squander that massive amount of kinetic energy. And they re-programmed the Jake to take advantage of that idle RPM while downhill.
