Jayco Logo

Jayco, Inc. was founded in 1968 by a man of strong faith and vision. The late Lloyd J. Bontrager, family man and inventor, felt he could build the world a better RV. He longed to create a company of his own, one that clearly reflected his ideals: a company where everyone would be treated as "family".

With encouragement from his wife Bertha, Lloyd started Jayco on their farm--in two chicken houses and a barn! He developed his own prototype camping trailer and a unique lifter system for fold-down campers, the basic design of which is patented and still in use today. By the end of 1968, his fledging company of 15 employees had sold 132 fold-down camping trailers.

Today, Jayco's "family" of employees has grown to nearly 1,500 people, while more than 25,000 people join our "extended family" of customers each year.

At Jayco, our mission statement is: Committed to being the most respected name in recreation vehicles. We will consistently build a high quality, high value, competitively priced product at acceptable margins, treat every situation with the highest level of integrity in a timely manner, and continually work to reduce total cost to achieve acceptable returns.
