New Chevy / GMC 3500HD options

I have driven three different 2020/2021 trucks. I have had three different tailgates. The power up and down would be what I will order on a LTZ. The multi-pro tailgate is useful in some scenarios. Of course, I had a standard bed (so Grit dog knows I only play with my toys) so flipping to prevent the 8ft lumber from sliding was extremely convenient with the multi-pro. I found it more convenient to have the power up tailgate overall.

I would put the heavy duty front springs on the vehicle. The vehicle I ordered and drove for 4 months did contain them.

The standard tailgate is powered and you can push a button inside the cab to raise or lower it.

Given the ability to, I would pick a manual tailgate. I can't imagine the "standard" tailgate is a power gate though?
If you are asking yourself "why would he say that?" then you don't really use a truck bed for work and go ahead and pick the fanciest power/swiss army knife gate you can.
I’ve heard they make for good conversation pieces when tailgating!
