What is currently the shortest class B out there.

I gotta ask, why shortest?

the only advantage I can see is parking--- with a longer/wider you may have to park farther and walk to the store.

but you still have height restrictions and once you punch a hole in the air, MPG isn;t much affected by vehicle length

a shorter wheelbase will have a rougher ride

interior space is lessened.

so please, why?
