Totally agree... A couple more minor differences that come to mind are the captains chairs and "leather" accent panels in the cabinetry. I don't know the exact years, but the late 00's and early teens have reported flaking and peeling (including my 2010).
Also, the cab interior got a face-lift starting in 2015 chassis models (which may or may not align exactly with the 2015 coach year). This directly affects your Ford options and after market add-ons (adaptive cruise, Lane keeping, LED lighting, dog house upgrades, steering wheel button integration, etc).
