Your post made this woman RVer laugh. I started out with a B, and then moved up to a 25' wider body Class C some years later. Even so the 2nd time I drove it, the result wasn't a long visit to a body shop, but only a couple days to do a bit of paint repair. :B Dang weatherstrip on the garage door jumped out when I wasn't looking. Oddly, on the road, my bigger rig drives so much better than my little B did... but that is the difference between an older Ford and a newer Chevy. It sounds like your smaller Sprinter will be perfect for your usage.
Have Fun!!
