Safari Condo M18 model is 17'9" (213 inches) long, probably the shortest production Class B currently offered in North America. Sportsmobile also offers custom units based on that same Promaster chassis with either low roof (pop-top) or fixed high roof options. The high roof Sportsmobile design with cross-wise dinette bed would probably be the shortest Class B with full sleeping, bath, and cooking facilities available.
At our previous house one advantage of those shorter units would have been fitting inside the third garage bay, which was taller and shorter than the main double bay. That would have avoided all HOA and storage issues associated with a larger RV.
