Thankful

I just don't like the "feel" of the gas engines. I haven't tried the new 6.6 gasser, but the 6.2 didn't feel as good as the diesel.

I've had 5 or 6 Duramaxes since 2005 and during that time I went back to a gasser twice, (a 5.3 and a 6.2). I promise you, I won't make the mistake of going back to a gasser unless absolutely necessary. After driving a Duramax for the last 15 years, I wasn't happy with a gas engine.

My 2018 had squeaky brakes, and after the third visit and complaint the dealer replaced the front pads. It fixed it for a while and then started up again but not as bad. I traded it for a 2019.

Yes, I drive about 6 to 8 thousand miles each year and I'll put some fresh DEF in about twice each year. I've had 4 Duramaxes which require DEF and none have ever given me a warning of "bad" DEF. Here is some data I found: "The shelf life of DEF is a function of ambient storage temperature. DEF will degrade over time depending on temperature and exposure to sun light. Expectations for shelf life as defined by ISO Spec 22241-3 are the minimum expectations for shelf life when stored at constant temperatures. If stored between 10 and 90 deg F, shelf life will easily be one year. If the maximum temperature does not exceed approximately 75 deg F for an extended period of time, the shelf life will be two years."

I measured it (approximately) 104 inches.

In a 2020 model, using a USB flash drive is basically plugging it in and giving the Infotainment head unit a few minutes to analyze the files and then you choose the flash drive as the source and hit the play button. You can get this SanDisk 32GB Ultra Fit USB 3.1 Flash Drive for $7.99 at Amazon.

I chose the Denali mainly because I like the Denali grill better. If you like the SLT grill better and the options are about the same, then I'd go with the SLT. Other than the grill when the trucks have the same options, there's not much difference.

The holes are there. But you can buy these caps to cover / fill them. https://www.amazon.com/ES-ENGINEERED-SCHILDMEIER-Pocket-Silverado/dp/B07KVKN9PZ/ref=pd_sbs_263_1/134-3934545-0413839?_encoding=UTF8&pd_rd_i=B07KVKN9PZ&pd_rd_r=beb637b4-46d2-461c-8efe-d84eb19b9a8d&pd_rd_w=4Vr8E&pd_rd_wg=NGSVt&pf_rd_p=12b8d3e2-e203-4b23-a8bc-68a7d2806477&pf_rd_r=70MMKXB09XFFPQZW6PBX&psc=1&refRID=70MMKXB09XFFPQZW6PBX

The dealer here charges $200. A local body shop said they'd do it for a hundred. If it's not too difficult, I'd rather do it myself. If you get your hands on the instructions, and have time, would you take a quick pic and upload it?

Has anyone replaced the standard black wheel mouldings with the body color wheel mouldings (GM part 84237183)? Does anyone have the installation instructions? I've searched and searched for the instructions to see if I'm able to install them myself. I don't see any screws or black taps on the existing mouldings so I wonder if they simply pop on underneath the splash guards. I've found them for around $532, and they look a lot better than the standard black. You'd think they'd put the body color ones on the Denali trucks automatically.

Nice!

Search eBay. You can find them for as low as $20.

I read several years ago, somewhere, that the oil life monitor utilizes time more than anything else. It's possible, since your truck was built nearly a year ago that the oil life is down to 40%. I don't know why it would alternate between 40% and 89%. Since you're planning on changing it at 1,000 miles, I wouldn't worry about it. When you change it, reset it, and everything will be fine.

I agree with redwngr. I think it started with the 2017 model year. I used to have a 2017 and it was the first that I remember having it. I didn't know the half tons had it.
