  1. Depending on which trim level and options you have, there’s a bunch of stuff back there that can rattle:
  2. it will be interesting to see what it takes to install the tube. Appreciate your willingness to be the test subject.
  3. Would be great to see pictures of your install if you’re willing to post. Especially interested to see how you route the air duct if you decide to install it. Also what hardware you use to attach the charging module to the console. There are 4 screws shown that attach the charger tray but I see nothing in the schematic for attaching the charging module to the tray. Does it just rest in the tray without any screws?
  4. Unless something with GM has changed, dealers won’t (can’t) reprogram for tire size changes unless you buy a GMPP wheel package that comes with a reprogramming code. Dealer can’t even reprogram to the largest stock factory tire size without a code from a wheel package. I’ve tried and with four different dealers.
  5. It doesn’t matter. The dealer (or you if you have a TPMS relearn tool) can sync the sensors no matter what the tire pressure is at. Just add/remove air as necessary to get to 42psi. Also, since you are adding new TPMS sensors, make sure you buy the correct sensors as there is 315mHz and 433mHz frequency sensors. They are not interchangeable. Your dealer can tell you which you need.
  6. At 300 mph you’d actually be going 304.36 mph. The tire diameter difference between 265/60 and 275/60 is only 0.2” to 0.3”. For 285/55 at 300 mph you’d actually be going 298.37 mph so slightly under speed. Speed differences under 100 mph will be nearly insignificant to notice.
  7. There are LOTS of threads on this subject. Some people have had luck with many brands and sizes using either the factory wheels or aftermarket. Some people have to trim or remove mud guards etc etc to get what tires they want to fit. That said, with my experience, using the factory 20” wheels you can fit LT275/60/R20 or LT285/55/R20 on ANY factory 19-21 T1 truck with no issues or modifications necessary. It may be possible to go with a bigger size but your application depending on the brand and model you choose will vary.
  8. Not the same. They are completely different. They make a chrome handle kit (or buy them each separately) for the 19-21 Silverado. This only if you do not have the passive entry buttons on the handles. Changing out the handles is SUPER easy on the 19-21 models and only tool required is the proper size torx driver, but only if you don’t have the passive entry buttons. The passive entry buttons are wired through the door frame and present a much more difficult change out.
  9. Took about a month but I finally have all the parts to do this. Did you need to source any hardware? I already see I need a couple screws for attaching the air duct.
  10. Here check this out: May help give an understanding of what you may be dealing with as I did on my 20 LTZ.
  11. I’ve had a 19 LT and a 20 LTZ and both worked flawlessly. have 300 miles on my 21 LT TB and noticed this right away when walking away from the truck at work. Didn’t auto lock the first day and thought I missed a setting. Confirmed setting and still have the issue happened at least a few times. Haven’t driven the truck much so haven’t experimented a lot but seems to happen when the rear door is opened for a longer period of time, like when I’m unloading my truck for work in the morning. Auto lock always works when using only the driver door. Also if I open and close
  12. SOLD SOLD SOLD I have 4 Goodyear Wrangler Territory MT tires, size LT265/60/r20 for sale in Phoenix, AZ. Tires have 250 miles on them and are factory take-offs from a 2021 Silverado Trail Boss. This is the factory tire when ordered with 20 inch wheels. No damage to tires and still look brand new. I will be posting pictures this weekend. $800 for the set. Prefer a local sale. I can accept Zelle, ApplePay, USPS Money Order, or Cash. I can accommodate shipping but will have to get you a quote for your Zip code. Contact me by PM if interested.
  13. i wonder if you could unplug the hitch view camera and plug in a front view camera in its place on the head unit. Then, on the menu screen, when you press the hitch view soft button you would get the front camera view. If it works, this would be a good option for people who would really prefer a front camera rather than seeing the top down hitch view, which is really only meant to check your trailer hitch connection while driving.
  14. Having the bed view camera undoubtedly means that you will have at least the 5 channel VPM mounted behind the rear seat. Having a VPM in this location is the base requirement for being able to install other cameras using factory installation methods. But what if you have the Advanced Trailering Package that has the HD Rear Camera and also the Second Hitch View Camera? Do these two cameras plug into a VPM behind the rear seat? Or, do they plug directly into the Infotainment head unit near the front passenger footwell? Is having a third camera (bed-view) the minimum to have VP
  15. Interesting. I’m certain mine was correct then something changed. I would have noticed this issue a long time ago if it’s how it came from the factory. Strange thing is my wife’s 2018 traverse premier has surround vision and it is perfect all the way around with no distortion of any kind. If GM can get it right on this car, why not my truck? Seems like lazy software calibration done by a third-rate hack computer engineer at GM.
