Holiday Rambler Corporation is an American corporation which primarily manufactures recreational vehicles. It was founded in 1953. In 1961, Holiday Rambler’s introduction of aluminum body framing ushered in a new era of lighter, stronger and more durable recreational vehicles (RVs). This aluminum frame (Alumaframe) became the standard for lighter and stronger RVs for 40 years. Holiday Rambler was also responsible for many firsts; built-in refrigerators, holding tanks and aerodynamic radiused corners. As Holiday Rambler moved into motorhomes, they were the first with tag axles and the kitchen slide-out revolutionized "interior engineering" in the field. Holiday Rambler was sold to Harley-Davidson in 1986 and later in 1996 to the Monaco Coach Corporation where its future, then under Navistar International Corp., was difficult in 2010 as it was for most motorhome manufacturers.
