Does your 2005 Duramax have an aftermarket exhaust brake.
Exhaust brakes are now standard equipment and make a big difference
No it just has the allison holding back going down a grade. Has worked great on any mountain we have towed on. Heavier fifth wheels should have a truck with the exhaust brake. chevman
