Nothing really changed from 2019-2020 suspension wise on T1. Engine/Transmission combinations with the 10 speed. Yes.
Now from your K2, yes. Whole new frame and all. Reduced weight can also factor in to the Suspension feel.
However, Suspension is a loose term. You have to consider the package types in this. Such as Z71/X31 Vs 2wd, 4wd Max Tow etc.
The list goes on and on.
OP, I recommend you test drive several trim levels/suspension packages to see what fits your comfort level best.
Compared to your 2014 K2, A 19 or 20 T1 with similar setup may ride better or worse to you.
Same with the Transmission.
Although a 2020 model will give you more options with the 10 speed combo over a leftover '19 model this late in the year.
Good luck!
