I'm gonna go with AMCGuy here...the engineers do it for a reason. My guess is that these engines are both more efficient and also much tighter than the old stuff most are used to. Tight tolerances need oil, especially when they are cold and 20W50 ain't gettin in those tiny spaces.

I have the exact same problem with my 2020 Trail Boss LT. It is super weird because one day when it dropped into the 20's, I had ice on my windshield. Not on the outside of it, but on the inside. Anyone ever scraped the inside of their windshield? No water on floor board, no obvious leaks.

Scooby, I like your style but have to disagree about the speed. Doing 100+ mph on the freeway is dangerous because of the crazy drivers, even if you can see way out in front and to the sides, but doing that on a country road invites big trouble from the stray deer, dog, or farm animal. You may not be the problem but you aren't alone out there. BTW, you are one of the few that understands that pickups are really limited in speed by the driveshaft although, your government does control your top speed for the tires you have too.

I had the exact same problem on my 2020 Trail Boss and I rotated every 8,000 miles. Two days ago I had an alignment done by the dealer and both toe and camber were out of spec. I think that the factory sets the toe in just beyond spec to make the ride feel more stable until you buy it. I had the same problem with my 2005 Tahoe. Alignment fixed it...not the tires fault.

I think it is primarily supposed to be for charging batteries, some lighting and/or a radio. Let's face it, 400 watts isn't enough to run anything bigger than maybe a jigsaw or medium drill.

Todd308, "That's right a whole team of truck engineers thought it was a better idea to save 50 lbs of fuel on a 5500lb truck to gain some tiny fraction of MPG rating, than give the driver 20% more driving range." The engineers are driven by the US Government in their fuel mileage needs. CAFE standards dictate what they have to obtain for the fleet, just like in the old days when you ordered a Camaro Z28 and didn't specify high performance tires, the US Government forced GM to put a speed limiter on the car for 105 mph - tire speed rating. Just think, the new Camaro and Corvette models are being de-tuned because of the CAFE standards...

Thanks for getting the specs right CamGTP. I have the 5.3L with the Chevy Performance Intake/Tune and with 89 Octane, there is a noticeable difference in performance. The tune makes the difference and I believe is also why the standard 5.3L gets the 87 octane nod rather than the 91 given that both engines sport almost identical compression ratios.

Good photos, sorry you had the trouble. You are correct in how they can't fix a darn thing nowadays. I had a microswitch problem, unlike yours, with a Shark vacuum. Same deal though - wanted to replace the whole head of the vacuum for $90 because the beater bar wouldn't work. I went to Ebay and bought a $3 microswitch, threw in a little solder and boom, the thing works like new.

I installed the GM Performance Intake which is essentially a cold air intake (but aren't they all?). Anyway, I've had mine in for over 10,000 miles and haven't had a single problem. Like mentioned before, when I bought the upgrade, it came with a "free" program flash for the ECU to adjust for the different air flow. Prior to getting the computer flashed, my truck ran a little rough. My guess is you need an update so that the sensors understand the new flow rate of your intake.

It seems kinda simple to this country boy redneck but couldn't you get the tires you want and just have the speedo reprogrammed?

I'm curious, what engine do you have in your Denali? It is a nice looking rig, by the way. I'm also wondering about the Airstream trailer...why Airstream and not one of the ultralights that have slides? I am thinking about a camper/trailer but know nothing about them. Thanks.

Ken, the truck looks great. As for the topic here, I have the stock Goodyear Duratracs on my truck with 11,000 miles on them and they have been great. Off road they perform and on road they only whine a little. I couldn't be happier even if they are the stock tire. As for the tire width, you really do need to check max turn on the wheel wells...

Great shots from all, however, the truck looks like it could use a little TLC...I thought I saw some mud on the side. ?

Congrats on the new truck! I am on my 3rd and hope that this is the charm. I am loving my 2020 Silverado Trail Boss.

I almost bought the RST but instead picked the Trail Boss. You made the right choice although your 0-60 times just went up a bit...

Unfortunately, I just changed my oil and found that it was 2.5 quarts low. I change all of my own oil and I have never had this happen on my truck (62,000 miles now). This is the first oil change after my 5.3L threw a P0307 code. After checking the code and finding that it was a cylinder 7 misfire, I replaced the plug and the wire. What I found when I pulled the plug blew my mind...a cracked insulator on the plug electrode. What I didn't know was that this was a common problem with Chevy 5.3L motors that have AFM but was "supposed" to be fixed after 2011. I can assure you that it isn't fixed and now I am thinking about trading or selling and going Toyota so that this doesn't happen again. The real problem is that I am just outside the powertrain warranty so the $5,000 cost to rebuild the engine would be on me. Update: 10/17/18 Called GM corporate and was given a case. The "Senior Service Representative" called me and discussed the issue. By the time I got off the phone, I realized that this was a losing battle. Despite the fact that I had the GM Service Bulletin #10-06-01-008M that called out my engine code specifically, she repeatedly told me that my VIN didn't pull up that bulletin. So I asked her, can you tell me my engine code based on my VIN, she couldn't. I told her that my engine code was listed in the bulletin and she just repeated that it didn't cover my VIN. When I asked her if she wanted a copy of the picture of my spark plug, she told me that she wouldn't know what she was looking at. In the end, I had to go see the Service Manager at my dealer and he laid out the scenarios for me. Since I reported the problem before the end of my powertrain warranty, GM might help pay for the repair but I have to get the dealer to do an oil consumption study. That study has to show that I burn 1 qt. every 750 miles or GM probably won't do anything. Since I am now out of my warranty, GM might cover 30% of the repair. Buyer beware... Plug #7 after being replaced (10,000 miles on it) Update 10/30/18 Called GM corporate back and the Senior Advisor informed me that indeed, the TSB listed above did apply to my vehicle. She made it clear that GM wanted to help me but that I would have to coordinate with the Service Manager at my dealership. So, I went to talk with him and he was very blunt about the situation. Basically, since my truck was out of warranty (despite me trying to get help while it was still in warranty) they might provide 30% on the repairs but I would have to do an oil consumption study first. If it wasn't burning one quart in 750 miles, GM would do nothing. The bottom line was that I was just screwed, however, the Service Manager told me that he would push to get me Customer Loyalty Cash and he did. They gave me $2,500 to trade and buy a new truck. I did just that and they sold my problem in 3 days because it was very clean, had brand new Michelins on it and it runs good despite the oil/rings/afm problem. Buyer beware!
