    Best All-Around Tonneau cover 2021 Chevy Silverado

    I have the same BAK revolver X2 cover. I really like it, and I don't have the "winter" issue as I live in Florida. The additional Pro I would add is that it rolls up into a smaller size than the fold up covers do, which leaves more of the bed open when you need as much of it uncovered as possible.

    3.0 engine vibrations at idle

    This probably sounds like a dumb question, but when the auto shut-off stops and re-starts the engine, it causes a shudder. Could that be what you are feeling?

    Removing the front air dam on a 2020 AT4.... what about the wheel well liners?

    So I was looking at removing the front air dam on my 2020 AT4, but it looks like the wheel well liners would be exposed and hanging down. Has anyone else tried this?

    Fuel Mileage

    Just from the trucks internal trip, I'm getting about 18 to 20 MPG around Miami in traffic. About 17 when I'm towing a boat. Highway miles it jumps up to about 27mpg. I haven't kept track when I'm going off road / dirt roads.

    Recently bought a 2020 1500 AT4 Diesel.... Hi there!

    No problem at all. In fact, on the day I took that pic, it was a bit rainy, and the tide was super low, revealing the slimy bottom section of the ramp. Other 4WD gas trucks around me were revving up and spinning their tires. I just put mine into trailer mode, put it into full time 4WD high...

    Backup lights

    That's pretty cool, but do those top cargo lights help illuminate the road / area behind you as you are reversing? Do you have this mod?

    Backup lights

    Actually that's interesting. Are they difficult to install?

    Backup lights

    Love my truck, but I could use some better lighting in reverse. I tried to change out the reversing bulbs, but then realized that the AT4 package is a sealed unit, so you can't get to the bulbs individually. Anyone have any ideas about mods to give more light when backing up?

    Recently bought a 2020 1500 AT4 Diesel.... Hi there!

    Hey everyone. I live in FL, but I go up to NC several times a year. Use the truck to tow boats, and to go off road for some hunting in the mountains. Looking forward to getting to know you! I have a 2020 GMC 1500 AT4 Diesel in the Dark Sky Metallic, and I was lucky to find one with pretty...
