Thanks Dan, and I agree with you on test driving multiple trucks. I had read that the leaf springs are different on the 2020’s but not sure which package, etc. One member said it was a pretty significant difference over the 2019 he had. That being said, to get into a 2020 SLT with the 10 speed I would have to get a 4x4 which I’m not necessarily against but in my 16 years of driving I have never needed it (South Florida and now Austin Texas), so don’t really want the added expense. Granted it will be worth more down the road so I guess it’s a wash. There is a 2019 Denali that’s relatively stripped down, which still has absolutely everything and the interior is the dark brown instead of tan or black, really looks sharp. Like the digital gauges as well. I can get that truck for $45k vs a 2020 SLT 4wd for $47 ish. Leaning towards the Denali at this point but will make a final decision once I test drive a few.

Thanks for all the replies guys, really appreciate it! Question for you - what trim do you have to get to get the 10 speed. After looking around it looks like most of the 2020 SLT’s in my area have the 5.3 and 8 speed. Is the 10 speed an option assuming it doesn’t come standard? Nevermind - answered my own question, in Denalis, AT4, and 4wd SLE and above. Problem is I only need RWD. Decisions decisions. Sent from my iPhone using Tapatalk

Hey All, I am looking at pulling the trigger on a new truck relatively soon. I am curious how much better the suspension tuning and 10 speed transmission are vs the 2019 8 speed and suspension. I know the only real answer is to get out and drive both which I plan to do soon. Both would be the 5.3L. Are the 2019 8 speeds having the same issues as the previous years or are they fixed? Seems like from reading the 2019 got a new torque converter and has better programming. There are some 2020 GMC Sierra SLT's that are popping up for around $11k off which is nice (I would have to drive about 3 hours to make that deal), but I can get a 2019 Denali for $12-$13k off right now at the local dealer. Rather have a Denali but if tranny and suspension updates are that big of a difference I will probably go for the 2020 SLT. Thanks in advance for any insight!

Thanks for the reply Kyle, I remember seeing your post about replacing the axles and driveshaft on yours. Axles got rid of most of the vibration right? With the driveshaft fixing the rest of it?

I have been a part of this thread since almost the beginning with my 14 Sierra and I am considering biting the bullet and just getting a new truck. Problem is, I don't drive all that much, truck is paid off, and it only has 30k miles on the clock. Low and behold, like many others the vibe is completely random. The temp here is 54 deg and my tire pressure dropped to 31 psi. Got on the highway, absolutely ZERO vibration from 70-76. The other day when it was 80 deg here, tires were at 33 psi and shook like it always does. No rhyme or reason, same highway. My first thought is tires, but no way 2 psi would make it violently shake vs not shake. Wondering if its the contraction and expansion of the metal, i.e. driveshaft, axels, something with very tight tolerances that when it is warm out are somewhat expanded causing the issue and when it gets cold out contract to the proper specs. I am at a loss at this point and like I said, considering trading it in - but with my limited driving it sure is nice not having a truck payment.

Welp, went with the 295/60’s, hope they fit! Sent from my iPhone using Tapatalk

Alright guys, time for some new tires. I currently have the following setup: 2014 Sierra 1500 2" RC Level 20x9 0 offset LRG wheels 305/55/20 Nitto Terra Grappler G2's Would really like a tad skinnier / slightly taller tire but not sure if it will fit, limiting factor being the offset. 1st choice: 295/60/20 Cooper AT3 XLT 2nd Choice is a toss up between same size I have now and the 285-60-20 Cooper AT3 XLT None of the Cooper dealers have the 295/60-20 in stock so I can't see if they'll fit. Any thoughts? I know it will be really close as the 305 slightly rubs the carpet liner now on the very edge of the tire. Not sure if since the 295 is skinnier if it will rub because of the height vs width. Racked my brain on this for a while so forgive me if this is a stupid question. Thanks in advance!

How do you like these tires so far? Considering replacing mine with the same.

How’d you pull that off? Well done sir! Sent from my iPhone using Tapatalk

You shouldn’t have any vibrations to be honest. Saw your other thread and that’s about where an out of balance tire shows up. I’d drive on them for a couple hundred miles and take them back and have them road forced. I had a set of tires that mounted up the first time perfectly and changed in that few hundred and they rebalanced them and good to go. Sent from my iPhone using Tapatalk

Good point haha, other than that much difference? They’re giving me a great deal on my 2014 trade in so might pull the trigger before it depreciates a whole lot more. Sent from my iPhone using Tapatalk

Pretty much in the same boat here. What are some of the advantages of the 2020 over a late 2019 model year build? Sent from my iPhone using Tapatalk

Hey all, I am in the market for a 2019 Sierra and there are some killer deals to be had right now. Seems since the 19's are on the way out I can't find the exact truck I am looking for so I'll have to compromise a little. Ideally I'd like to get a White Frost SLT with Sunroof, Dark Walnut Interior and Driver Alert Package, but can't find that so the two options are as follows: Truck 1: White Frost, Sunroof, Driver Alert Package and Black Interior or Truck 2: Summit White, No Sunroof, No Driver Alert Package and Dark Walnut Interior I can live without the Sunroof, but is the Driver Alert Package worth it? I won't use the lane departure, but its nice to have the side monitor and front parking sensors. Would you guys compromise on interior color to get a few other options? I currently have a 2014 White Diamond Tricoat Sierra with a black interior, which is why I was looking to switch it up and not get the identical truck in a 2019.

Curious what you did to fix your vibration? I’m having an internal dilemma right now because my truck is paid off, but has the vibration which is why I would be trading it. Don’t really want to give GM more of my money after these issues but damnit if it isn’t the best truck out there in my opinion right now. Seems the issue is fixed on the 19’s and have worked a deal for $15k off sticker and a good amount for my trade. That being said if I can fix my vibration I’d much rather keep a paid off truck.
