Don't know about the MPG, But on the down hill. Gas has got diesels beat. They already hold back the truck and trailer. All you got to do. Is drop down thru the gear box.
Diesels have to add some sort of brake (trany, Exhaust, engine) to make a diesel do what a gas engine does naturally. With out some sort of add on. A diesel just free wheels down a hill, in ANY gear. I understand many manufacturers are putting them in their truck either as a option, or in some cases standard equipment. It should be required.
I can come down from Blowing Rock, 7 miles of 6 to 7% grade, with sharp curves and hardly touch the brakes.
???????
In a gas truck you gear down and hope you don't blow the motor by over revving it coming down or up a step grade. Have you ever driven a diesel? Exhaust breaks are added to diesel to pull loads you can only dream of pulling with a gasser.
You know. I really have driven a diesel. A CLT9000, double wide, air ride, with a Fuller roadranger 13 double over. No Jake. Hauling 80,000lbs, More at times. Have you???? Becaue Exhaust BRAKES are added to diesels NOT to tow heavy, but to slow them down coming down the mountain. They don't need Jakes to pull..
BTW Breaks are what you do when you stop working. BRAKES are what you use to stop a vehicle. And diesels FREE WHEEL down the mountain without a add on engine brake.
