If the dealership balanced them twice without resolving the issue then they should still be looking for the source of the problem. Have you told the dealership they haven't fixed the problem? If so, what did they say? if not, that's your next step. I wouldn't let the dealership off the hook yet, there's plenty they can do other than just a basic spin balance, i.e., PicoScope with NVH kit, Road Force Balance, rotate tires, replace tires, etc., etc. JMHO No expertise implied or expressed
I am suspect under the intended use you describe you would not likely have an issue. However it does prompt some thoughts: Why does GM use extended CV axles on the TB/AT4 which is only a 2" lift over the standard 1500 series truck? Why does the only factory authorized lift sold on the GM accessories web page include longer CV axles? In both cases the droop stops remain in place restricting the movement, yet, GM still thinks it's important to extend the CV axles. Why is it often recommended to remove, or at least loosen, the CV axles from the wheel spindle to reduce the stress when replacing the strut assembly? Aftermarket parts are often an improvement over factory parts and automotive engineers aren't all geniuses (I have 2 in my family). However, it does make one wonder why GM would go through the trouble of having 2 different length CV axles if lifting on the standard axle length didn't present some issues during testing and development. Just some thoughts. No expertise implied or expressed
Nice! I asked if you were sure, not because I question your claim, because I have read other posts where people claimed to have had the factory ITBC installed only to find out it was an aftermarket brake controller installed by their dealership (so they assumed it was the factory setup). I wonder why the vast majority of posters on this and other forums were told it couldn't be done? Dealerships have actually lost truck sales because they said they couldn't do it. If it's that easy, it seems they would be offering to install them to make the sale instead of telling people it can't be done. Even a search of the 42 towing accessories listed at the Chevrolet Accessories web page for the 2020 Silverado shows only 2 brake controllers available, the Curt Spectrum and the Curt Echo. Why wouldn't they list the OEM option if it's available and so simple to install? Did the dealership provide you with any documentation regarding the install that you can share with others to assist them in their quest to get this done? Personally this is not an issue for me as my truck came with the factory ITBC, I am just hoping someone can provide some clear and convincing evidence so this can be definitely be answered and others can get the ITBC installed as they wish. Right now everyone is at the mercy of their possibly ignorant dealership. Any documentation that can be shown to the dealership would be useful. I am not trying to be difficult or argumentative. It is just the vast majority of posts, on this forum and others, claim this can't be done and those that claim it can have never (that I've seen) provided evidence of such.

Are you sure it is a factory integrated brake controller? It should look like the picture attached if it is a factory integrated brake controller (the subject of this thread). If it doesn't look like the picture than it's just an aftermarket brake controller your dealership sells.
Seeing that one of the goals of a public truck forum is to help fellow owners, it would be really helpful if anyone who has had this done provided some documentation and photos, if available. The common belief is this can't be done. This forum, and others, have plenty of stories of failed attempts and only a couple that claim success. So again, if you have had this done, how about providing copies of the work orders, (redacted of course) photos of the completed install, (before and after would be even better), and help clarify this issue. Otherwise, it is just another unsubstantiated internet claim. I know I was told by 3 dealerships that it couldn't be done on my 2018 Colorado, That's why I purchased my SIlverado with the factory brake controller. JMHO No expertise implied or expressed.
Just because the engineered design allows for movement through a specific range doesn't mean it's designed to operate in that condition on a regular basis long term. The engine is designed to run up to red line, so it must be okay to run at red line on all the time, right? I mean, it's in the engineered range of operation so it must be okay, just drive in 2nd gear all the time. GM engineered the front suspension to run from a 0" lift on the standard 1500 to the 2" lift on the TB/AT4. Does that mean the suspension travel doesn't allow for a 3.5" (or 1.5" on the TB) lift to be installed? No. Does it mean it was actually engineered and designed for a 3.5" lift?, also No. Droop normally occurs when the wheel/suspension is not under load on a truck without additional lift. Lifted, that same droop/ball joint angle now occurs under continuous load. So is the ball joint designed to be under load on a continuous basis at the higher angle now created by the droop that's a result of the additional lift? Just because the suspension moves through that range of motion doesn't necessarily mean it's designed to be under continuous, or additional, load throughout that entire, or even a greater, range of movement. You can run a tire under inflated under extreme conditions (off road for example) and some are engineered for that type of usage. That doesn't mean it's engineered be run at highway speeds while under inflated. Just as suspension is designed to droop for travel on varying terrain, or pot holes, it may not be designed to be artificially drooped (specially under load) at all times by a lift over 2". However, just like you can run an underinflated tire at highway speeds (I don't recommend it), you can run a suspension at lift imposed droop at all times (doesn't mean it was engineered to do so). The theory that because a component is engineered to perform under varying conditions on a short term or sporadic basis, it's engineered to run in that condition continuously and long term is questionable. GM engineered the factory suspension to function properly from 0" to 2" of lift (or standard 1500 to TB/AT4). Any claim otherwise is pure conjecture. If anyone can provide GM engineering specs that claim otherwise, I'll happily eat my words. Just as I wouldn't drive with my engine at red line (designed to hit red line under certain conditions) or highway speeds on an underinflated tire (designed for underinflated use under certain conditions), I wouldn't lift a standard 1500 over 2" or a TB/AT4 at all with factory components. The absence of failure is not a confirmation of appropriate usage. JMHO No expertise implied or expressed
I think this is what has prompted all the discussion about consistency and protocol adherence in measurement because this defies logic. I am not stating or implying you aren't losing/burning oil at an accelerated rate because you could be. I am just saying without following the measurement protocol it's impossible to rule out a measurement error. So the question is, are you actually burning/losing oil in an illogical, erratic fashion or does it just appear so due to how you're checking your oil? If the truck is actually burning/losing oil in the manner described, I'd get rid of it. Please let us know what you discover. JMHO No expertise implied or expressed

Truck Hero now owns all of these brands (from their website): " Truck Hero’s industry-leading family of brands includes Advantage Truck Accessories™, Alloy USA®, AMP Research®, A.R.E.®, Auto Ventshade®, BAK Industries®, BACKRACK®, BedRug®, Belmor®, Bushwacker®, Extang®, Husky Liners®, LUND®, N-FAB®, OMIX™, Rampage Products®, Retrax®, RoadWorks®, Roll-N-Lock®, Rugged Liner®, Rugged Ridge®, Stampede™, Superlift®, Tonno Pro®, TruXedo®, UnderCover®, and an online retailer, RealTruck®. " You'll notice Go Rhino is not one of their brands (read between the lines). The advertised price for the GO Rhino RB20 Running Boards is the same on RealTruck.com and Autoanything.com. However, my experience with Autoanything.com is that if you use the chat or call and tell them you are looking for a better price, they often offer a discount. I always use the chat and they send me a link to the discounted price. Of course now that you asked to cancel the order it will magically ship. Good luck and let us know how it turns out.

I agree and so does the 2020 manual (pg.336): Follow these guidelines: To get an accurate reading, park the vehicle on level ground. Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep grades or too soon after engine shutoff can result in incorrect readings. Accuracy improves when checking a cold engine prior to starting. Remove the dipstick and check the level. (emphasis added) Good way to insure "the engine has been off for at least two hours" and the oil is checked "prior to starting" is to check it before for the first drive/start of the day.

MY 2020 RST/Z71 just did this for the first time today. It was exactly as described sounded like an acorn dropped on the roof twice but I was no where near trees. I also had the rear window leak fixed about a month ago and they claim to have used the new bolt kit when replacing the spoiler. I wonder if it will keep happening?
