Unmatched speedometer
Well, that’s pretty simple, actually; the right side of your truck is going faster than the left. Probably due to rust on your differential. You just need to steer a bit to the left until it corrects.
Seriously, I would find that fairly annoying as well. Hope you’re not too OCD. Is the analog gauge a direct physical linkage? Anybody know it there’s a way to adjust it? Is it always off the same ~2 MPH, or is it off by a percentage of the speed?

LOL! Not sure if there is a physical linkage. Its always off 2-3 mph regardless of speed.
Looks like could be about 1mph difference.
My 2016 was similar but not as pronounced.
The digital display does not show decimals. Depending on the rounding value you could be at 79.6 to 80.4 for it to show 80. Given the needle looks like 82, you could be about 80.4 on digital and be just 1mph off.
Not exactly what I would call an issue but I know what you're saying.
Because of the unnecessary redundancy, I decided that two units of measure on the display was silly so never used the digital display.

1) There are, for example, speeds between 80 and 81. The digital gauge is displaying speeds that are rounded to the nearest mile per hour where the analog gauge is not rounded. It displays every speed between 80 and 81. The analog gauge has the potential of being more accurate than the digital gauge. Considering wear and the variation of the air pressure in your tires as you drive neither one is completely accurate.
2) Perfect electrical components that are required to do the Analog to Digital or Digital to Analog conversions don't exist. There are going to be manufacturing differences (tolerances) of some degree in the components that are used to convert analog to digital or digital to analog. There are going to be manufacturing differences (tolerances) between different analog gauges. All of the tolerances will add up in a random fashion so that one truck will read slightly different (randomly) from another even if they are both running at the same speed.
Is it annoying? Only if you let it be. I wouldn't worry about it.

One would assume there is one speed sensor, and the analog gauge is electrically driven. I wouldn’t be surprised if there was an adjustable correction factor the truck applies, like I believe there is for the MPG calculation. Perhaps it can be tweaked in forscan?
