We were the only manufacturer in 2008 to increase our market share in all four major RV categories, travel trailers, fifth wheels, Class As, and Class Cs. The Bus industry is expected to benefit from the American Recovery and Reinvestment Act (the federal stimulus package) which includes $8.4 billion for mass transportation,” said Wade F. B. Thompson, Thor chairman.
