What class of RV is a Rialta?
Browse our extensive inventory of new and used Winnebago Rialta class c RVs and motorhomes from local Winnebago dealers and private sellers. So why did Winnebago stop making the Rialta motorhome? It actually appears because Volkswagen stopped importing the Eurovan (powertrain and chassis for the Rialta) to the USA in 2003 and the supply of ’03 chassis’ that Winnebago had stockpiled ran out in 2005.
