I ussually average about 13.5 miles per gallon constantly.

Any suggestions on where to go thru the cowl for my plow wiring, got my push plates and everything else installed, now looking for a good spot to go theu the cowl, any ideas appreciatted, photos if possible would be a big help.

I have a 2024 2500HD 6.6 gas and I am getting the same whining noise, but mine has gotten louder over time, used to only hear at slower speeds just starting out, now it is louder and here it almost all the time, going into the dealer next Monday, see what they say.

Dealer has ordered a new HMI module for my Pick Up, they were not able to reset it with the latest update, I feel better about getting a new one instead of a reset.

Test drove a used 2018 2500LTZ everything worked fine, bought the truck, went to pick it up today, at the dealer when i got in, it had black screen, only reverse camera works, radio still works but who knows what station it is on. They advised me to bring it back tomorrow to re program it while i wait, after reading this thread i am nervous. truck is out of warranty.

Had to drill my 2011 Silverado 2500HD Extra cab, just traded that in for a 2018 Crew Cab, took everything out of the 2011, will be drilling again on the 2018, has to be done if you want a plow. bruklnboy, that looks real nice, i would have done the same thing, cannot believe the instructions say leave it off.
