The Ultra Van crowns itself as the world's largest production Corvair by way of an aluminum and fiberglass monococque shell wrapped around a Corvair transaxle. As the Ultra Van itself was conceived by aircraft designer David Peterson, the biggest Corvair is more like an aluminum airplane wing in the round than a conventional body-on-frame RV. Only about 370 Ultra Vans were ever produced. 250 of them still roam the roads. The Ultra Van is affectionately known among club members as the whale. This nickname sprang from truckers overheard on a CB radio referring to a caravan of the World's Largest Corvairs as funny little white whales on wheels. Ultra Van, ahoy! Fudgie the whale is still hanging out at your participating Carvel ice cream store.
