When RVs are outlawed, only us outlaws will have RVs. The Hole-in-the-Roof Gang?I'm near DC, and I'm sure I've seen similar signs along the streets down town and in other historic areas in VA, MD, and PA. I see it mostly in areas where pedestrian traffic is the norm mostly out of necessity because the streets are so narrow and for safety reasons. Vehicle traffic or pedestrians do have a difficult time seeing around these larger than normal vehicles. I saw this...interesting.
