Loren Cayo was an avid sportsman and camper as were his friends Allen Grams and Larry Zuhl. They wanted a recreational vehicle that could be used with full hookups, or be self-contained when hookups were not available. Allen and Larry were building contractors. These backgrounds were a good blend and in 1955 the Avion Coach Corporation was formed in Benton Harbor, Michigan. The goal was to build America’s finest travel trailer. Allen Grams served as President of the Corporation for the first several years. The company prospered and by 1967 was operating plants in Benton Township Michigan and San Jacinto California. Loren passed away suddenly from a heart attack at age 51. In 1970, controlling interest in the Avion Coach Corporation was sold by the Cayo family to a Detroit family headed by Robert M. Ligon. Ligon Enterprises, who continued to build and market the same high quality product. In 1976 Ligon Enterprises sold the company to Fleetwood Enterprises. The Silver Avion was built until the 1990’s when Fleetwood decided to build the Avion Product with more traditional RV construction methods.
