Why does everyone assume you have to lift the front to level a truck? You can also lower the rear...

Exactly 1 year and just under 4000 miles since the fluid change and it fixed my shudder issues. Includes a 700 mile tow in there as well, some of which was through mountains. At least in my case, it looks like the fluid was the total solution.

The idea of taking parts of existing inventory doesn't make much sense. A dealer has sunk costs into those vehicles, paying interest on them sitting there, along with a lack of opportunity to make money on those vehicles while awaiting parts. Unless GM would compensate them for that (doubtful) it would be against the dealership's best interest to do that.

Lemon laws are state-by-state, so someone from a different state likely has different rules to deal with. For me, if I had an equal loaner, fine and dandy if they have my truck for months - I'll put miles on the loaner instead. But a loaner that isn't comparable, that's a much bigger issue, as I own a truck to do truck things. The shortage may not be something in GM's control, but at the same time, you are the one without a brand new truck. I would recommend contacting an attorney.

From the GM builder site, it doesn't appear that the CarbonPro package has any impact on the wheels. In either case, the dealer has identical trucks other than the CarbonPro package, both with the 20" Carbon Gray wheel upgrade.

AT4 and Denali come with a spray in bedliner and the SLT does if is has the Premium Plus package. So if you want a well equipped Sierra, it will have a spray in bedliner already, so this really does cost you $1000.

You either overpaid for the truck or got screwed on a trade in. Excluding insurance (cheap) and gas, if I sell to Carvana today, I will lose $4960. My numbers include every penny of maintenance, registration, taxes, even the flight to the dealer to pick it up as I didn't buy local. That loss is also assuming I wouldn't just pull my catch can and tonneau cover and sell on my own (that's an easy $500 doing a quick sale).

I did a bit more research, and the spray-in liner is standard on the AT4 and Denali for the T1 trucks, so that can't be figured into the savings. It is part of the Premium Plus package on the SLT, which was the same as when I bought my SLT.

Sitting is the bigger issues than short trips, as the truck can go 1-2 weeks without being used at a time, especially in the spring and fall. Other than my local towing trips, most of my drives are 15-30 minutes each way (leaning more toward 30 minutes), mixed conditions (45 - 55MPH roads, a little stop and go, some freeway). Then the 2-3 multi-state trips a year. I previously had a daily driver BMW 335i when I commuted to the office, but since I work from home, I bought my C6Z then sold my 335i, so the truck now takes the place of some of that car's duties.

The CabonPro bed isn't a bed liner. The entire bed is made of the material, meaning it doesn't need a bed liner, or wheel well liners. Not an equivalent comparison.

I did some searches, and only came up with folks not being able to find a Tonneau cover (doesn't seem to be as big of an issue now), or that their truck has it. I can't find anything on whether it is worth having it. The option forces you into the Kicker MultiPro speakers - I can't think of a use case for me where I would use them. Otherwise, what does it really get you? I assume all the regular beds get the spray in liner now from GMC as I don't see it as an option (was part of a package on my '18), so not needing a liner really isn't an advantage. Slightly more room in the bed doesn't seem like it is worth the money. I get that it is lighter but trucks tend to be light in the rear anyway, so not a big advantage there. I'm all for new tech, but can someone explain the real world value to this package? Edit: Looking further, I think what really screws you on the price of this bed is that damn speaker package you are forced to take. That's an $815 stand-alone option. You can also buy it on its own and add it to the truck; a 30 second search found it for $572, part number 19417163. If someone wants that option, it make a lot more sense to just add it later (it doesn't look hard to install). Unfortunately, this forced option is really the driving factor for the cost of the CarbonPro bed...without that requirement, it would likely be a $500 - $600 option.

If you can replace your truck with a 4 door sedan, you didn't need a truck, My wife has a B8.5 S4 (I'd personally avoid the 2.0T in the A4's). Fun, nice cars but a pain in the ass to work on and maintenance hogs. I do it, but don't enjoy it!

Unless you plan to keep the truck forever, that $7000 argument holds no water. Diesel 3/4 and 1 ton truck have a higher resale value than their gas counterparts, so you pay more on the front end but get more back on the back end. As for the 150k mile belt, even if you keep the truck for its life, that's what, a 1 time expense? At 150k, only an idiot would be paying a dealer for that job. Probably a $2500 job assuming you aren't addressing any other issues while in there (refreshing the torque converter, rear main seal, etc.) At 15,000 miles a year, that's maintenance hits at 10 years. Sock $250/year ($20.83/month) into your piggy bank and it will pay for that maintenance. IMO, not that big of a deal based on its service life.

I'm not overly thrilled with the sound of the L86 in my truck either, but don't want it louder. I like the sound quiet in my trucks. Where did I ever say 95% of my driving was 2 miles? My statement was clear that most of my towing was 2 miles, but I do more than tow with this truck. I never said I liked the 2.7, I just said for my local towing that even it would work. The highest level truck you can buy with that motor is the Elevation and you can't get the "leather" seats, Tech Package, etc. on that - all dead set requirements. Though stripper trucks would be much cheaper, they also resale for less, so I'd rather wrap up some additional cash and increase the enjoyment of my drive. If Cadillac still sold the Escalade EXT, I would own another one, as I preferred how it drove vs my Sierra. But I need a truck bed and GM decided to axe that platform.

2.7L is only offered in the lower spec trucks. I'm also not looking for a major powerplant downgrade - I also won't consider the 5.3L. The reason I'm considering the diesel is the $1500 lower cost compared to the 6.2L and much easier to come by. Other than the local tows for boating, all of my other driving does get the oil fully to temp, but the truck will sit for 1-2 weeks at a time, as I'll take my car out in nice weather and I've been putting miles on the wife's for family trips as well.

Sounds like it will tow fine but I should probably drive one at a local dealer to make sure I like how the diesel drives on its own.

It seems that Carvana wants to offer more for my 2.5 year old '18 Sierra SLT than I paid for it new (other than tax). It is making me consider an upgrade to a Denali Ultimate or a loaded up AT4. I tow a 5000ish lb boat. Most of my towing is a 2 mile drive maxing at 45MPH, where the 2.7L 4 banger would suffice. But about twice a year we do a 700 mile round trip going through the Kentucky and Tennessee mountains. On those trips, we are loaded with gear and around 7000lbs total with gear/passengers. I will also likely upgrade to a bit larger boat in the next couple of years, expecting that number to climb to 8000lbs. I may also begin racing/towing my car, but that will end up being lighter than the boat. I'm happy with the 6.2L / 8-speed tranny combo I have today. I know I will be happy with the 6.2L / 10-speed combo. Will I be happy with the diesel? I don't put a lot of miles on the truck (10,500 in 2.5 years). The diesels are more plentiful and significantly cheaper. I can get a crew AT4 with Tech, Driver Alert II, Sunroof, AT4 value, tow mirrors, with the diesel for $54,500 out the door (plus tax). About $3500ish more for a Denali Ultimate. Thoughts on one engine vs the other? I was planning on keeping my current truck 5-10 years and if it wasn't for today's stupid high resale, I wouldn't be considering getting rid of it as it has been a great.

Don't waste your money. You will not see enough performance gain on a stock truck to bother with it. Money would be much better spent on a proper tune and E85 conversion.

It's now 2021. Is this upgrade path ever going to happen?

Should add a flex fuel sensor and tune for E85 as well.

Truck won't be down a few weeks. 1-3 business days if you send them yours + shipping, which is $199. Or send them another TCM and they will program it for you for $299 then you just swap TCM's and have zero down time. It would be $900 all in, plus $250 if you go with the Pro Feature set (useful for adding wideband logging). In 2 years when my warranty is up, I'll be doing this on my truck for E85 tuning and a little other stuff. Currently buying it + wideband for my car now to retune the hack job a "pro" tuner did on the car by the previous owner.

Handheld tuners are a joke. Get the HP Tuners MPVI2.

Except they got in bed with Mobil for the answer, which this might shock you, also costs them money. So how does Mobil not cost them more money but Amsoil does? Please explain.

There was some sort of dealer-installed option available when new that gave at least some of this functionality but it wasn't cheap and I don't believe developed by GM.
