Exactly what I did. Just for your info: My 2011 was a Silverado Crewcab LT w/NHT 6.2 with 80k in great condition. I got 20k for a trade. 2017 is GMC SLT Premium package w/6.2. Paid 43.5k w/out ttl. Sticker was 57k. Just to give you an idea of what my deal was. Boston area. Hope this helps
The only issue I've had is the super bright backup cam. Dealer updated and works perfect now. Being in a similar position as the OP, I would keep your eye out for a truck you want and if they give you a deal you are comfortable with I'd do it. This generation is definitely more refined than the last.
This is the 2nd GM truck I've had with afm. My 1st was an 09 that had to have the pistons and rings replaced under warranty at 27k miles. One month after repairs it was down almost 2qts of oil. I traded it on my 2011 with the 6.2 because it didn't have afm. With my 17 I don't think there is anything wrong with the afm but I can feel a sluggishness to the acceleration with afm active. With it disabled it just feels quicker and more powerful. Ive also noticed the mpg penalty over my last 5k miles is negligible.
I recently did exactly what you are thinking about doing. I traded my 2011 NHT 6.2 for a 2017 SLT 6.2. The 8 speed is different and takes some getting used to and blackbear CANNOT tune the 8 speeds. I hate the afm. Coming from a truck that didn't have it, I can feel it everytime it goes into 4 cylinder mode so I got the range device. It makes a big difference but I will be having blackbear tune it out soon. The truck itself is much better, its quieter, smoother and tighter. I'm glad I got my 17 even tho I loved my 11 for the 7yrs I had it.

mferry22 replied to tyhuck's topic in 1999-2006 & 2007-2013 Chevrolet Silverado & GMC Sierra 1500I was down 2 to 3 quarts in my 2009 and the low warning never came on.
mferry22 replied to CCRyder's topic in 1999-2006 & 2007-2013 Chevrolet Silverado & GMC Sierra 1500I had an '09 that had the center jump seat and only a power driver seat and it had factory heated seats with no issues. I dont think a power passenger seat should matter. You might want to try a different dealer.
mferry22 replied to tonyghkbve's topic in 1999-2006 & 2007-2013 Chevrolet Silverado & GMC Sierra 1500My 2009 was down 3 qrts and the oil light never came on. I found out because I checked my oil the old fashioned way.
I bought some oem 20s for my truck a few months ago with no tpms. Now that the snow is finally gone I want to get them installed on my truck. I went to 2 places to get a price to have the sensors switched from my stock 17s to the 20s and have the 20s put on the truck. Both places said they couldnt switch the sensors for different reasons. One place said it couldnt be done because I need tpms for 20s and mine are made for 17s so I need new sensors. The other place said the sensors are glued to the wheel so they cant be removed. Is any of this true? I didnt realize this would be such a process to have these tpms swithed and the wheels installed.
