The KWs are for the senior drivers. They don't have as much interior storage, though.

The 9400i's were being phased out with ProStars, but they stopped ordering those and are switching to Cascadias, so I've heard. There aren't any new ProStars at the terminals, anyway.

The problem I have with this company is they keep cutting staff and poor internal communications. It would be hard for them to get any worse. But they do try.
