The Vanguard refrigerated trailer is engineered to protect temperature-sensitive freight while driving down your cost of ownership. Tested to be 12% more thermally efficient than competing brands, its smooth, foamed insulated panels and triple rear door seal hold precise temperatures with less work from the reefer unit—translating directly into fuel savings and longer refrigeration-unit life. Galvanized steel components throughout resist corrosion and cut maintenance costs, while stronger floors and smart weight distribution add durability and stronger resale value down the road.
