O Town Denali

I have the one I pulled out of my 2016 Sierra Denali with the 6.2. I do not know if it is compatible. It has been out of the truck since I traded it in 2019. $50.00 shipped. Venmo, Zelle, Apple pay

I think you received inaccurate info. The DFM disabler does both.

Yes, the light on the stop/start switch stays on. Check to see that all 4 LED on the range are on when cruising. My first one was defective and they sent me a new one. For me, the truck is much more responsive with the range activated. Also shifts better, no more clunking. 5.3/8 speed

I have a 2019 5.3/8 speed. I came out of a 2016 6.2/8 speed. This new combo works for me just fine. Here is my lifetime mileage. I do not change my driving style for fuel mileage at all. Whatever it is, it is.

Yes, on the outside I keep a rolled up towel in my truck specifically to cover the vent . It doesn't happen often but is a real pain when it does.

Lots of people running the range device. You can perform a search on it and see the threads. Well worth it in my opinion.

Another benefit: I would think that a basic Denali would have a higher resale value vs a loaded to max SLT ( which is about the same price).

It is either a 7mm or 9/32. I used the 7mm. No extension needed. Can't hurt to check them. Takes 2 minutes.

My 2016 Denali had a fantastic ride and my 2019 is even better. No bouncing. Smooth as butter.

About 1 mpg with 75% highway driving. About 50 gallons/year in my case. Hypothetically of course. ?

Call Range. They can reprogram it for the 2019. They will not guarantee it though for the 10 speed.

Yes, normal. Warning lights light up when key is turned to show they are working. When truck starts they should turn off. It is when truck is running and you have warning lights you can worry.

Steering wheel sensor off is my guess

Nice mod. I use mine to reach into the front of the bed often.
