Main differences?

Hello all,

First post here, but long time lurker My question is regarding the main difference between Classic, Classic XL, and Columbia. I'm going to orientation at a company that I worked for last year, for about 6 months. I will be driving Midwest regional, same as last time, company driver.

The company offers the models mentioned above, 2006 and newer, all condo. All have DD 60 12.7, with mainly 13 speeds, some 10. My first time around I drove a Columbia. It was a decent truck, turned well, comfortable, good interior room and storage, good viewing range with mirriors for backing. A little bumpy/shaky going down the road (insert freightshaker comments), but all around decent truck.

So with all of that in mind, of my likes and dislikes, what would I be in for if I decided to take a Classic or XL? Longer wheelbase, harder to turn? How much so? Better ride? Smoother down the road? I've heard from other drivers that the classic styles are easier to live in and drive day to day. So what's all of your opinions?

And yes I've used the search bar, darn near to death. I couldn't find a post that asked/discussed specifically what I'm asking. Thank you all for your input!
