I'm not sure my exhaust brake works, I have been messing with it from day one and have never felt it work, I push down the switch and my little trailer light thingy comes on the dash but nothing seams to be happening
I personally hate this exhaust brake idea.
It does very little beside reving the **** out of the motor. I think it is a total wast of wear and tear on the motor.
I don’t want my diesel reving to 4K on a small brake application. It’s just stupid.
I have multiple trailers and even with my little utility trailer there is no noticeable speed reduction just a lot of diesel noise. I have tried this multiple times and always end up turning off tow mode when slowing for an exit off the hwy.
And if I can’t tell any difference with my little utility trailer I am damn sure it’s not going to be of any value slowing my RV.....
Even without a trailer taking the same exit as always coming home from work, turning on trailer tow and having the diesel motor rev it’s ass off makes little to no difference in the amount of brake pedal pressure I need to slow the truck for the downhill exit ramp. It’s just to small of a motor to make any useful difference.
