A real jake would be nice. However, since there wasn't enough room to put a real Jake on the current trucks and the new truck has 30% less underhood space and the engine is tucked under the cowling even further I don't see any way it could happen. A true Jake brake make's the engine even taller (it installs on top of the cylinder head/valve train) and I can tell you for sure that there is NO way there will be the room on the new truck! Even with a bulged hood 3 of the cylinders are under the cowl so you'd have to cut up the dash and the windshield to make it fit. Not too likely IMO
