U-Haul rents its branded trucks, vans, and other moving equipment for both one-way and in-town moving. U-Haul conducts its rental business through a network of about 1,200 company-owned rental centers and about 14,500 independent dealers. U-Haul describes its relationship with the dealers as an agency. 

U-Haul agrees in the dealership contract to bear the risk of liability incurred by the dealers’ U-Haul rental operations and to assume responsibility for loss due to theft, vandalism, or other damage to U-Haul equipment in their possession. U-Haul fixes flat rates for in-town rentals based on the size of the truck rented. Is U-Haul engaged in price fixing in violation of Section 1 of the Sherman Act? Explain.
