Big ones with 10 wheels...what difference does it make? If you want a job, drive the truck they put you in. I drove a Mercedes powered Columbia the other day and it was dreadful, but my truck was in the shop, so its either drive it or stay home and stay broke.
It makes a big difference to me...As a previous owner, I plan on purchasing another truck and it would be great if it is one that I am comfortable in and enjoy driving. If it does not matter to you that is your problem and your choice. But it makes all the difference to me.
