Poor Ride With Newer Trucks?

I have a question for experienced drivers. I've been driving since 2010. I started out in a fairly new Cascadia. Then after 2 years I changed companies and drove an older Freightliner Classic with the long nose. Since then I've been in several other newer Cascadias and Pro Stars. Now I'm in a 2017 Cascadia. It seems to me that these newer trucks from about the last 3 years do a whole lot of rocking front to back when I'm driving that those older trucks didn't do. The older trucks seem to have driven smoother. Has anyone else experienced this? I'm not even sure if the problem is with the seats or the suspension of the trucks.

Not sure about that, I do know the 2020 fraightliner I drove while with Schneider rode smoother than the 2016 I had before that.

Generally the lighter the truck the more rocking and jumping it will do Freightshakers aren't the best riding trucks to begin with in my experience.

Jump into a heavy Volvo 780 and you can leave a drink open and on the rear table and finding sitting where you left it after your driving shift. Which I've done. A Pete 579 (I think?) Was just a little less in quality as far as ride then the Volvo. Kenworth T880 - T800 And for me the Freightliner is kinda at the bottom of the list as far as trucks I've driven in terms of ride quality.

And I've never driven an FL classic so I can't really compare but I wouldn't imagine that's a light truck. So it probably does ride pretty smooth.

Count your blessings you've never run in a Ford W9000 cabover. I guess Ford knew they dropped the ball there. They introduced the CL9000. Talk about the proverbial ,"night and day"
