I was ready to buy a 2018 3500 DRW Longhorn until............ I read that for 2019 there was a change, maybe 2. The first change is the nav screen is going from the current 8.5" to a large 12" touch...
I understand that it will be model year '20. Probably at least a year away. That touch screen looks very intriguing. It would be awesome to have dual displays. You could have your NAV on one half, and your choice on the other half. Perhaps a rear view camera on your trailer...
