According to the Recreational Vehicle Industry Association, nearly one in twelve U.S. households that owns a vehicle also owns an RV. That accounts for nearly 7 million households that are RV owners. In a University of Michigan study, the “typical” RV owner is 49 years old and married. Of Americans over the age of 55, a full 10 percent are RV owners, while the largest group of RV owners by far is the baby boomers (35–54 years of age). As the baby boomers age, the percentage of RV owners who are over 55, and the total number of RVs on the road, should increase substantially. Older owners typically have more disposable income and time to travel.
