I wonder if that Freightliner cab is the same as the Coronado's we tried a few years ago. They rattled and squeaked from day one, but I could tolerate that. The thing that made me crazy was not being able to see the speedometer or tachometer while driving. They were tucked behind the steering wheel in a way I couldn't see them.
I hope they keep the WS interior, use the FL cab if that's what they want.
None of it really matters to me. The 2018 4900ex will be the last truck I drive. I've been offered a new 4900ex glider twice since I've gotten mine, and I won't give mine up for anything.
