    Good lord it’s hard to watch people throw bricks at a brand new $70,000 truck. Any truck can run through a water filled ditch. Trashing a new truck proves nothing. I wish these manufacturers would find more meaningful ways to test their vehicles.

        The locker isn't it the same thing that comes in the regular Chevy /gmc truck?

          With bigger tires and shocks should be good

            HELLO GM YOU LISTENING . . . . .
            WE WANT FRONT AND REAR LOCKERS . . . . . ON ALL OFF ROAD FOCUSED MODELS. I'm fine with just a rear Locker on the regular 4x4s but on an off-road Focused truck like the AT4 you better put them on the front and the rear otherwise what's the point.

                Lockers front and rear would help on the rocks and if you are going say "will it conquer mud?", try putting it through some real mud and not just a puddle!

                      Gas 6.2 truck torque is way off and over rated!!!
                      I hope the baby duramax is rated properly.
                      I am in the new L5P and this is way way faster then my 2018 6.2L omg they did it right
                      Thanks GM!!!

                            Lost me when they designed them so you have to remove the trans to change the fuel pump belt.

                              Not a fan of the Sierra but I like it in at4 trim. Much better then the lame Trailboss.

                                  I guess you could use it to tow a real offroad vehicle to the trails

                                      It didn't look like the G80 locker was working. GM needs to go to an electronic locker, and ditch the one from the 1970s.

                                      Looks like at 4:03, they should have made it a 3" lift with rock rails instead of a 2" lift without rock rails. Then it hits again at 4:10. I give GMC credit for making a challenging rock hill. The truck barely makes it up the hill.

                                                  Thanks for the awesome off road, daily, work truck and Chevy/GMC content video, I love my 2010 Sierra Crew Cab SLT (I’ve had for 6+ years, 90 of 160k miles) and look forward to buying a NEW AT4 1500 or 2500 in a couple years but still not sure on which. I’m thinking Duramax 2500; but for as little as I tow my little show truck bagged S10, I’m still thinking 2500 at the moment. I’ll see what the 2021/2022 has and then I will know. I just hope Chevy/GMC keeps the 1500 Diesel for my options later on. Thanks TFL truck, love the videos. All you guys are awesome and I hope the more words I type help you out, lol. Thanks again. Love the Hummer H2, Land Rover, Toureg stuff and more, too. So many cool trucks and SUV’s all the time, I need a bigger garage and driveway. You guys are the best.

                                                    You're going to be better off with the Duramax 2500HD

                                                  You should try a Chevy Trail Boss and a GMC Sierra off-road comparison.

                                                      @Zraupp10 maybe! My dads always said you win the lottery by working, he's one the last few to achieve the american dream. He came to this country at a young age, with nothing but the cloths on his back and a dream. He's a successful buisness owner now. Has everthing the amercian dream consists of. I aspire to be like my dad someday. Thats why he says you win the lottery by working. But hell, i wouldnt mind winning either!!

                                                            It would be nice to see a Torsen style front limited slip like the Raptor has. Even the Tremor is getting a limited slip in the front as it should. I also like that GM hasn't went to the huge screen display on the dash. The Dodge has that and it just looks stupid to me. If I'm not going to watch movies on it I only want the screen big enough to do the job and not look like an I-Pad got stuck to the center stack.

                                                                            That mans face, when his creation is refer as a glorified trail boss, “ just a little prettier” priceless 😹😹😹😹🙌
                                                                            The only thing I like about gmc truck is the suspension and the tail gate, other than that the trail boss has the better meaner/faster appearance.
                                                                            Luxury more electronics=more expensive stuff to break and fix.
                                                                            The best off-road truck to buy at 62k, hands down is the ford raptor, but the towing and fuel economy sucks. for 43k for sure you get a lot more truck with a trail boss vs a gladiator that goes for the same price.
                                                                            If I was to change anything about the trail boss is Kings shocks vs rancho, Mickey Thompson’s atz p3s, would add Fab Four front bumper, and the entire sliding down back window, similar to H3 hummer SUT.
