Fleetwood is a huge company, with numerous brands and models of RVs as well as manufactured housing. They participate in nearly all price brackets and thus produce models with widely differing levels of quality and amenities and offer different levels of warranty and customer service. I'd say that Fleetwood is "average" overall.
Unfortunately, the Rv industry is not known for consistency of quality in any brand, regardless of price. There is a chance, perhaps as high as 5%, that any new Rv you purchase will require numerous repairs in its forst year or so and it can be very frustrating. Many people buy used just for that reason.
