A big difference between those trucks as far as the ride quality is spring rates. The 2017 can carry more weight so it needs a higher spring rate.
The cost of that higher spring rate is while driving unloaded the suspension is stiffer. What happens is there is less movement of the springs going over bumps so the shocks can't do their job, which is dampen the spring movement.
What you can do is upgrade the seats to have air ride :D That is going to be the next upgrade. Just wait. Pickups will be towing 40k lbs with air ride seats like a big rig.
