My 2020 AT4 6.2L had 2 flappers, one before and one after the muffler, I know for sure because I did the work myself. Sorry I don't have them anymore, but with a good muffler, you don't need any flappers. I put on the GM performance system and sounds great. Sent from my Pixel 4 XL using Tapatalk

Yep, I've had my sensors installed since March. Been to the lake weekly since, they work great. Sent from my Pixel 4 XL using Tapatalk

Just fyi, you can unlock doors and unfold mirrors without opening windows, you just don't hold unlock as long. Sent from my Pixel 4 XL using Tapatalk

Different tranny, but just for comparison, my AT4 6.2/10speed, hottest I've ever seen it was going up a 7% grade pulling a 6k lb camper going 70mph at 112 outside temperature. Engine temp got very high, but tranny never went over 185 Sent from my Pixel 4 XL using Tapatalk

Many have said it's the borla touring system, but I don't know for sure. No tips included with the GM system, you just use the same rectangular dual rear tips already installed from stock. Sent from my Pixel 4 XL using Tapatalk

2020 AT4 Infotainment system update v148 March 5th 2020 Sent from my Pixel 4 XL using Tapatalk

I just saw this while researching dash cams. I wonder if it could ever be added to our 2020 infotainment ... And you're right "such a waste". I have 8 cameras surrounding my truck in high quality, yet I have to buy an aftermarket camera to be able to record anything... [emoji3525]. Stupid. What's everyone using for dash cams? I'm looking at thinkware Q800pro or u1000, but they are expensive Sent from my Pixel 4 XL using Tapatalk

Yup, I just removed mine yesterday as I prefer the larger console size without the locker. My gun is always on me, so don't need the safe. I just used a punch to push in the hole at bottom of knob and set code while holding it in. U can use paperclip or whatever, easy to do, not very secure. Sent from my Pixel 4 XL using Tapatalk

These are awesome if you trailer a lot, temps and pressures, with alarms if they get out of spec too far, could easily save you from a blowout. Sent from my Pixel 4 XL using Tapatalk

BakFlip MX4 works well on my 2020 AT4 with multipro tailgate. Also did not use the foam strip at front of bed. Sent from my Pixel 4 XL using Tapatalk

What trucks do you guys have? Engine/tranny ? Year? Sent from my Pixel 4 XL using Tapatalk

I like that idea, but how is your reach to the trailer brake controller with a phone mounted there? Sent from my Pixel 4 XL using Tapatalk

Additional battery, high output alternator(225a+), high idle switch and replacing the inverter for one capable of 1200-1500 watts min would all be required. Lots of work and cost to do it. Cheaper to just buy a stand alone gas generator if you use a lot of AC powered tools. Or go with a good quality battery setup. The battery chargers are ok in the 400watt receptacle... Just my 2c.

Both boat and camper around 5k-5.5k. tows great, love the 6.2L/10speed Sent from my Pixel 4 XL using Tapatalk

First at 1k, next 4k later at 5k, from now on every 5k mobile one synthetic Sent from my Pixel 4 XL using Tapatalk PS. Lots of towing after initial 1k and a fair bit of time in 4x4 off roading.
