I hope everyone is doing well! I had the pleasure of reviewing this awesome GMC sierra with the AT4 off road package. And I wanted to go over all the off road standard equipment that comes with the truck.

1. red tow hook - a perfect touch to signal the AT4 package.

2. 3L Duramax comes standard with the option of upgrading to the 6.2L v8 for some added top end power.

3. All-terrain tires in Goodyear duratracs, personally I think these are some decent tires and will give you some added grip in all situations.

4. upgraded 2 speed transfer case with 4wd low which is critical

5. skid plates, although I wish they had more

6. 2 inch factory lift which helps with ground clearance and approach and departure angles

7. 3.23 gears, personally I wish the AT4 package came with the 3.73 gear option which would really help with off road performance.

8. G80 automatic locking rear differential, honestly a great diff but I would again like to see something like an E-locker rather then an automotic locking diff that you can't control.
Hope you guys liked the review and the video!
