Nice truck and nice review. I have the same color but a 2020. A few of the things you mentioned can be tweaked a bit as you learn the system. I am still figuring things out as there are so many things that can be customized. Thanks for the great writeup and enjoy that new truck!

Good question. Following. I want to get a front end level done on mine, but afraid it will not allow me to park in the garage at work.

I traded in my 2014 1500 5.3 LTZ that was really decked out. I bought a 2020 2500HD LTZ 6.6 Duramax with all the bells and whistles. It only had 12k miles on it. I have a trailer about the size of yours and it pulls it like there is nothing hitched to the truck. I get about 20mpg when using as my daily driver and about 14mpg when pulling the trailer. I feel that it's been a great investment and I totally enjoy driving it every time I climb into it. Wishing you luck on your upgrade!

Google "2022 Chevrolet 3500 HD payload capacity" and the same for GMC. They are different capabilities with Chevy having a significant edge in both payload and towing capacities.....why I don't know. SRW is of course lower than DRW in both and Duramax significantly more capacity than gas.

I've recently acquired my first 2500HD. It came with LED headlights and they appear to be a non-serviceable unit. Where the dust-plug would normally be found on the housing, it is sealed. Are these things supposed to last forever? In all seriousness, I'm not happy with the light output of the stock headlights. The are a nice color at 5500-6000K, but just not a lot of output. My plan was to replace with some quality HIDs like I did in my 2014 1500, but now I'm wondering. Has anyone seen a replacement setup that would work on an OEM LED equipped truck?

I did that just last week. No issues.

I just put Nitto Ridge Grappler 35x12.50x20s on my 2020 and needed to do a 2inch level on the front to avoid major rubbing. I also put 20x9 +18 wheels on to match the stock size. You could also go with 20x10s, but trimming would likely be required at that point. I had no trimming required with the 35s on the 20x9 wheel.

Got my tow mirror project all finished up yesterday. I decided to go with the 1A Auto Trailridge mirror and can't be happier. I really want to thank @pgamboa for all of the fantastic information. I replaced a set of DL3 mirrors on my 2014 Silverado. In addition to the mirrors, I had to install the RZY harness to provide circuitry to the door connectors, and also ordered a kit from Phil to modify my door harnesses. With the videos that Phil has done, all of the pictures, and the wiring kit with great pictures and instructions, completing my upgrade was easy and satisfying! The new mirrors look great and I am very happy. Unfortunately, I was rear ended at high speed by an uninsured, unlicensed driver early this morning. He hit me so hard that the frame and the bed of the truck bowed. He bent my bumper and my class I receiver hitch down 12 inches. He also caused two other drivers to plow into us creating a huge mess. I was the only one who drove away. Unfortunately, I turn my truck in tomorrow for a complete frame replacement and a new bed. They will have it for a minimum of a month. Thankful that I am okay with only some soreness, but am really upset that my truck was damaged so badly and that I will lose her for at least a month. Thanks again Phil, for all the help you've given everyone here!!

I just got ALMOST done installing the Trail Ridge TR00284 /1AMRP01794 from 1A Auto. The picture on their website is not correct in that it shows the amber lenses on the markers and it actually comes with the smoked lenses (which I preferred). I ordered a set of jumpers to modify my OEM door harness from @pgamboaand will finish the door harnesses once I get the kit from him. I also had to install the RZY harness as the 2014 and early 2015 trucks with the DL3 option didn't come prewired for the towing mirrors (2015.5 and later did, early in this thread you can check the door connecter pins to see if your truck is already prewired or not). I have functionality on the power fold, power mirror adjust, turn signals, and puddle lamps right now, and will gain the spotlight and marker light functions once I get the kit in from Phil. I absolutely love these mirrors for both the fit and functionality they provide and they look fantastic. The most difficult part was wiring in the RZY harness, but you may not need to do this. Good luck on your project!

I just put the same set of mirrors on my 2014 with same options except chrome caps. I have some harnesses on order from @pgamboa but couldn't wait to get them installed once I opened the box. Right now I've got the RZY harness installed and will finish the job once the door harness kit gets here (to make the spot and marker lights functional) . Gotta tell ya, these are some quality mirrors and made all the difference in looks and function. I think you are going to be really happy with this mirror set. I think they look better than the GM upgrade mirrors. Really happy that the mirror/seat memory works too! Good luck with your project.

Just did this job a few weeks ago. Got a new condenser from Performance Radiator (they are national) for $125 and comes with a lifetime warranty and the two gaskets included plus a new stud for the trans cooler fitting. Went to Oreillys for 1 large bottle of synthetic refrigerant and one small bottle (both have the oil in them). I also rented the vacuum pump and manifold set to draw down the vacuum and remove water (this is why you need to run the vac pump for about an hour...the water in the lines will kill your compressor). The rental is free if you return the pump within 48 hours. Worked like a charm and no BS welds on the condenser like the GM OE. There are some great videos that show you how to do this step by step. Total out of pocket around $225 and 3.5 hours to do the entire job.
