Knobs and switches instead of everything running through the giant touchscreen was a huge push to make the swap.
2010 is the first year of the big cab which is the same as the 2020 so my kids still have the big back seat.
Pre DEF 6.7 which was really the only thing on the 2020 that ever had problems before it was deleted.
This one is a G56 truck. 2020 was an Aisin. I didn’t mind the auto but prefer the manual. Overdrive was better in the auto. The 10 is running about 10-12 mph slower at the same rpm in OD. 2k at 70mph vs 80 at 1800ish rpm. 5” straight pipe sings over 2k

The 2010 isn’t quite as comfy as the 2020 but I knew that going in. 20 was a loaded Longhorn and the 10 is an SLT. I do miss the a/c seats over everything else. 20 had all the extra insulation and active noise canceling stuff so it was a good bit quieter. The 10 rides surprisingly nice for a 1 ton truck. The 20 was a factory air-ride truck so it was a bit smoother but not massively so.
Overall I’m pretty happy with the swap. I lost a bit of tow capacity but gained payload going to the older dually but I’m still good for what I usually pull.
