Fleetwood is one of the oldest names in the RV industry. We’ve been around for over 65 years—more than double most of our competition. And that resilience speaks to our product. After all, a company can’t stay in business if they build something people don’t believe in. 


Inherently motorhomes are just that—a little bit vehicle, a little bit house. So at Fleetwood, we engineer and build them with both in mind. Our innovation shows we perfectly balance and blend the two. And that smarter design means a better RV.
