The downhill braking provided by an exhaust brake is similar to the gas engine’s with its throttle closed. It’s just shutting off the air post-engine rather than pre-engine.
I would get a gas truck if I buy a new one. They’ve regulated the economy out of new diesels.
The braking is not at all similar. The diesel brake is effective. Engine braking with a gasser hardly does anything.
I had a 2010 Ram with the Cummins diesel. The 2010 had minimal emissions controls and was the last year Cummins got by without DEF. Now I have a 2018 with DEF and extensive emissions controls. I drove the 2010 80,000 miles and the 2018 for 14,000 miles. I have the same camper and have recorded every drop of diesel I have used. The 2018 seems to have equivalent power and gets 15% better mileage.
