Rialta RVs were a collaboration between Winnebago Industries and Volkswagen from 1995 to 2005. The Rialta was the successor to the Winnebago LeSharo, shifting to the use of the Volkswagen Transporter T4 chassis rather than the Renault Trafic commercial van. Winnebago and Volkswagen ultimately made 3 RVs together on the T4 chassis, the Rialta, the Vista, and the Sunstar, the Rialta was the first and the most successful.
They were well-loved for their compact size, fuel efficiency, and versatility. Unfortunately, changes in emissions policies and the related discontinuation of the T4 EuroVan chassis were death sentences for the van. However, you can still spot them on the highway on a lucky day.
