In the spring of 2008, Entegra Coach became a member of the Jayco family of companies. Ever since, we've taken great pride in the details—and each luxury motorhome we build embodies that principle.

 

We started building luxury motorcoaches one at a time—with a superior foundation, unrelenting attention to detail and old-world craftsmanship, unmatched engineering innovation, rock-solid construction and a ride that's as smooth and quiet as it is invigorating and well-appointed.

 

In 2018, our pursuit of the superior luxury motorhome expanded beyond diesel Class A coaches to gas Class As and Class Cs. By building on experience and listening to customers, we're making the Entegra Coach luxury experience a reality for more travelers than ever. As always, we back each coach with personalized customer service and coverage that is unmatched in the industry.

 

So from the moment you drive off the lot, you're not only an owner—you're a member of the family
