Where I live (northern VA) only the newest and most accommodating spaces are wide enough to comfortably park my 2500 (new mall, or Costco). Most parking lots I have maybe 4" on each side of the truck once I carefully center it in the space and fold in the mirrors. A DRW would be even tougher in that environment.
When I was down in Florida a few weeks ago for work, it seemed like every parking space was designed to comfortably fit a DRW anywhere I went lol. My rental Mazda 3 felt extremely comfortable to park
