Public Relations for the Industry

The association has ongoing public relations programs that continue to develop positive images of the RV and campground industries. MARVAC keeps consumers, government officials, trade publications and media sources throughout the state informed by releasing a steady flow of information about the vital contributions the RV and campground industries make to Michigan’s tourism economy. Our programs are dedicated to creating positive images about the industry; we remind sources how our industry creates a more vibrant Michigan by constantly improving our recreation resources.

Communication-Publications and Seminars

One of the most important features of MARVAC is its ability to communicate information to its members quickly! MARVAC sends regular “Industry Insights” via e-mail to keep each member informed about legislation, changes in laws and government regulations, and current trends in the industry. The e-mail also lists activities and events which are important to manufacturers, dealers, campground owners and service companies.

Continuing education for members is a major priority of the association. Dealer, campground and service seminars have been highly successful at keeping our members informed. Through our seminars, members from all segments of the industry are kept up-to-date about new business procedures, legal and legislative issues, and governmental regulations that could affect their business and the industry. These seminars offer intense learning opportunities for members who are interested in sharpening their skills, and provides members with an opportunity to share information with industry experts.

Annual Outings and Public Shows

MARVAC’s annual outing combines a full range of seminars and workshops with social activities. The event provides members with an opportunity to discuss common problems and exchange ideas with industry associates. This event serves as a culmination point for the year as the association’s officers are welcomed for the new term.

MARVAC’s camper & RV shows are among the most heavily attended shows in Michigan with shows in Novi (2), Battle Creek, Port Huron, Flint, and Traverse City. Over 50,000 campers and potential RV buyers attend MARVAC shows each year.

Michigan Manufactured Housing RV & Campground Association – A Long History

September 19, 1941 gave birth to The Michigan Trailer Coach Dealer Association, Inc. It was the first state or regional association on record with continuous activity.

F.W. McKenny was the first director and was instrumental in the passage of the Michigan Trailer Coach Park Act in 1939. This is believed to be the first state wide legislation in the country regulating trailer parks. It was designed to replace all municipal laws and ordinances affecting parks. Other states used this as a model for similar legislation. In addition, McKenny was active in representing the Trailer Coach Dealers National Association during World War II. He moved his office to Washington, D.C. and in doing so took the Michigan Association office with him. In 1946 the association office was returned to Michigan and located in East Lansing. The name was then changed to the Michigan Trailer Coach Association.

In 1948, the members concerned with the operation of trailer parks formed a separate group, the Michigan Trailer Park Operators Association, Inc. This organization continued to represent the interests of the park owners until it again combined with the Michigan Mobile Home Association in 1966.
