It's not a specific requirement but it's one more thing that helps. Look at some of the all-time great M/Vs like Flash & Tom Kennedy's Whale, the La Contessa, or the Catbus. If it's something that isn't supposed to have wheels, it's so much more magic if it doesn't appear to have them.
Too much is not enough, and when in doubt double it.
