i had good interaction with: Autonation Chevrolet in Valencia and Sierra Chevrolet in Monrovia (Ask for Robert Rodriguez, straight shooter) which is where i got my RST

it was an infotainment update. hopefully kills all the bugs freezes and parasitic draw

I bought mine here: https://dmaxstore.com/products/

$3000 / 10 years is a good bet. Just to put it in the shop to run a diagnostic for a misc issue can cost $350 for a couple of hours of computer work. You’d hope that isn’t a yearly problem but do the math on that and you’ll be ok.

So I have a 2020 Silverado and I got a slew of these messages as I think I have a really bad battery. If your noticing that the truck is having a hard time starting up then a low power battery will throw multitudes of error codes. I had it the first time my battery died and I had it towed to the dealership and they couldn't replicate the issue. They jump started it and then the battery was "healthy". Still having some battery issues so I'm going back to ask them for a new battery or do a load test. Best maybe to start you truck and leave it running for a bit or drive around the neighborhood for 20 minutes. Turn it off. Start it again>?

call this place: https://www.tonneaufactoryoutlet.com/ Theyll quote you over the phone (just need to give them an email address) and it’s free shipping and maybe no tax and ask if there’s any rebates in play. I found them through a youtuber and i got it cheaper plus a rebate

share !

The replacement are the rear shocks. the GM 2” lift replaces the original Rancho shock with the Rancho Monotubes shocks which are in the AT4s and Trail Boss and they are a significant change in ride quality especially with high speed bumps.

nicely done. I went and actually got the Trail Boss stock suspension installed on my RST. I wouldn’t have minded powered mirrors but not enough for me to jump up a trim level On another note, looking at the 2021 Tahoe/Sierra AT4 off road trims with the adjustable lift control, GM decided that they not include the 3.0L Duramax as an option for off roading. That was disappointing to hear

So any idea if Duramax will be an option for the Trail Boss trim?

I’ve been told by many folks how awful the finish is for new cars from dealerships. After i brought home my truck, i proceeded to wash, clay bar, then polished it with a medium cut pad, glazed it, and then finished it with wax. WOW! I was amazed by that fact. Learned something new

I've wanted a truck for past six years. Still own my 09 Yukon Denali 180k miles and still going strong. But the interior is wearing badly so had been looking at 2500s but really didn't need to tow at the moment so dove in to 1500. Loved the TB but really wanted a diesel because the 6.2L on my Yukon can't do better than 14 mpg. So during covid I was having a hard time looking for an AT4 and after watching lots of YouTube I realized that Silverado RST was for me. I'm afraid of all the bugs I might run into since this is a Gen1 engine but love the torque and off-the-line launch. Just ordered the GM 2" "trail boss" lift and going to get that installed so essentially I get a TB w Diesel! Will post before/after.....

adding myself to see replies on this post as i just got the duramax. have yet to hear this pop and have a sunroof

What are you towing exactly? The decision to get the Max Towing package would be based on if you’re towing a camper and/or toys. Denali has max luxury features. You can almost add everything to the SLT sans the tag and chrome. Exclusive to Denali are the vented seats and rear seat luxury items. Note that if you’re going to do any suspension work in the future, the Denali comes with a different suspension versus the rest of the trims so that would not be an ideal selection but if you keep the ride stock, it’s a smooth ride.

Try VRP From Chemical Guys. Good stuff

i’ve been looking for a before/after pic of the GM kit. Thanks!

I just got one too. RST/Z71 and although the raking doesn’t bother me as much as Sagging if towing or loading, I’m debating between Rough Country 3.5” with strut extension vs the GM Performance 2” since they supply the front axle to address droop ... I worry about spacers because they can break if you go off roading although the Readylift spacers were at the base of the strut instead of the top where things can go wrong

I just got a RST too. Did you have the dealership install? Wanted to get a ballpark on dealer install cost...

Do you have Z71 package on the RST? I know that the Trail Boss use monotube shocks while the Z71 with factory lift are twin tube

i saw on youtube that AT4 or RSTs with factory 2” lifts require new ball joints if raising or leveling. Saw it on youtube and they stressed that. not sure if this relates to your situation. https://youtu.be/X1Pt00h5R3I
