Now at close to 20,000 miles on the 2020 a few more tidbits.
8 speed trans still doing great. I am amazed at the small rpm range this engine is designed to run in for fuel efficiency. Under normal acceleration I don't feel the shifts at all and even under hard acceleration the shifts are smooth.
If I remember to turn the auto stop off right after starting the truck it will idle fairly smoothly in that run cycle. If I forget and let the auto stop activate the truck will not idle smoothly during that run cycle even after turning the auto stop off.
Say what you want about the 8 speed's extra gearing making up for the 3.23 rear over the 6 speed with a 3.42 rear. My butt and the pull off of the line tell me different. I wish the 2020 had a 3.42 rear.
Still can't get the driver's seat "just right" on the 2020. The 2018 dialed in easily even after my wife drove it and changed all of my settings and was to most comfortable seat my butt has ever enjoyed in a truck.
I can't stand the electric parking brake. Unless I follow a specific procedure when releasing it and getting the truck moving from a stop there is a large jolt like the truck has been rear ended when I put the truck in drive. Start the truck. Foot on the brake. Release the parking brake. Shifter to reverse for a bit. Shifter to neutral for a bit. Then to drive. Otherwise I get hammered ! Does not matter level or inclined surfaces.
Jury is still out on the electric assist steering. Sometimes it feels quirky.
Missing the full center console I swapped in to the 2018 with Phil Gamboa's herness. If you can find a console for a 2020 they want close to 2 grand for it after shipping so that will have to wait. I had less than $600. 00 in the 2018 swap including the harness.
I like the power fold, turn signals, and paddle lamps on the 2018 and those options are not available to swap in on the 2020.
I've run 24 MPG over 400 miles average in the 2020 for weeks at a time and hit a couple of 25 MPG weeks in a row under the right conditions. 38 PSI in the tires yielded that but firm up the ride a bit. 34 PSI drops 1.5 -2 MPG. For a 4 door brick with an open bed that's not too shabby either way. The 2018 was within 1 MPG of the 2020, even with me enjoying the 3.42 rear from time to time.
I like my 2020, but in a perfect world if I could go back to my 2018 without electrical issues I would trade back for it in a heartbeat.
