We live in Anchorage and have new 2016 3500 Ext Diesel in Sandstone waiting in (long) line for a custom camper upfit at Van Specialties in Tualatin OR. We've gleaned many good ideas from this site. I only have a couple hundred miles on it so far, initial impression on handling in chaotic Portland area traffic is positive, and I think I'm already used to the automated manual transmission.
