So is this the cab layout you like? Very nice; I really like having the GPS in-dash as well :) I've never noticed the rotary light switches before; you're teaching an old dog new tricks! When I make my next truck purchase, I'll definitely be paying attention to the instrument/info panel and getting the best mix of info on it; right now, I'm torn between buying a new truck and buying my own trailer and exploring that whole "new" side of the game :D

Peterbilt 579 Duty Cabin dashboard. I like the rotary light switch, the digital info panel, and the decent in-built satnav.
