Well,
We've owned both and taken both factory tours.
When we buy a house, we go a lot but how it feels when we walk in the door, we want that warm, cozy, welcoming feel... and we do the same with RV's
Jayco gave us that feeling, and the Winnebago didn't. Winnebago seems to be going to the colder European look, which we don't care for. The tour in their Forest City plant was nice, but they didn't allow us to take photo's, which was a first for us.
All RV's have issues, heck, they're very complex, and move around a lot. So the Jayco 2 year warranty is very important to us. Also, the folks at the factory, and at the factory service center are friendly, competent, and bent over backwards to accommodate us.
We've had many different brands of both trailers and motorhomes, and are on our third Jayco.
Hope that helps!
Happy and safe camping!
