I think you questions apply to any Sprinter-based class C. They are all effectively the same size. The size and maneuverability are a definite plus in the national park campgrounds that often have small sites and tight roads. in a city they'll go anywhere a typical UPS or similar small truck will go, which is just about anywhere. The only difficulty I've had is sometimes with parking because the motorhome won't fit into a single car-sized space. For parallel parking it needs 2 spaces, and in a typical parking lot row, 4 spaces (2 wide + 2 long). It's obviously wider than a car, so parallel parking on a narrow street is iffy. A really small parking lot won't work, and there's sometimes the risk of going into a parking lot and not being able to turn around. Dimensions-wise, the Sprinter based class Cs are generally 6 inches narrower than those on a Ford or Chevy chassis. To go narrower you'd need to look at a class B.
