I've heard the exact opposite from tall guys, they prefer the Cascadias. I'm not tall, and I can see how the Volvos actually fit my shorter stature better. The seats are definitely better in the Volvos, and the cab is roomier, but I'm more used to the Cascadias. The biggest drawback w/ the Volvos is the release for the 5th wheel. I have to use a hook, which I don't have, just to be able to get to it easier. Otherwise, I'm rubbing up on the underside of the trailer getting grease / dirt on my arm and head... Then there's that annoying issue with the heater coming on in the middle of summer time, even if the controls are set to AC, when you first start up the Volvo.
But... I'll say that I think we are very fortunate to have such great equipment to drive. Yet another reason why I love OD. Seeing some of the tractors from other LTL companies makes me know how fortunate we are. We work for the best.
