I just bought a 2021 2500HD LTZ Z71 and added the transparent trailer kit to it. I tow a 24’ enclosed car trailer. The car trailer has an air dam (wind deflector) on the front upper section. After setting up the camera and calibrating, the invisible view was very distorted. I had two motorcycles following me within 2 car lengths, but the camera view made them look like they were 1/4 mile or so behind me. The side views on both sides look normal, but as soon as the trailer camera takes on the image, all objects immediately go from a few feet away view to far far away view.
Should my measurements have been taken from the front of the air dam or the front of the actual trailer? My measurements were taken from the front of the actual trailer.

See trailer in image.

I think that's the normal view - mine is the same.  It's a wide angle camera and that's pretty much how they work.  Everything in a wide angle is scrunched up to get as much into the view as possible and that makes close up objects look farther away.  Many passenger side mirrors work the same way and you will see an embossed message stating that "Objects in the mirror are closer than they appear."

Post a picture of the image and I can tell you what to change.  In most cases, the center of ball to front of trailer is wrong.  You need to assume the trailer has flat front don't include bubble.  Also for width, use box width not overall width.

I bought a new hitch shank that allowed me to lower the front of the trailer and make it more level, then remeasured the trailer and updated the info. When I hooked up the trailer, the image was perfect. Before, I couldn’t have known if a tractor rig was behind my trailer, let alone a motorcycle or any other vehicle. I love it!

    • HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.      
    • I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it. 
    • So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29. 
    • Any grease on the stud threads of any kind?   Wheel studs should have NOTHING on them for proper torquing and so the nuts don't back off.     Are all of the mating surfaces clean?  So wheel, rotor and hub?     We've had plenty of trucks at work with that wheel, this is a first to me.  Makes me think they've got a lube tech putting anti-seize on all the wheel studs or some kind of grease, and they need to stop doing that.  To have 11 other trucks with the same exact problem.      
    • I was a Chevy guy for years, then switched to GMC because I liked the looks better.  I'm actually thinking I like the Chevy looks better than GMC for the first time in a lot of years.   One thing I know for certain, the new GMC dash is hideous!  Chevy wins this one!
