The current Greyhawk line is pretty nice. We've had ours for 7 years now and have been pretty happy with it. The current Redhawk link is comparable to our Greyhawk. There have been a few things that needed to be repaired/replaced, but most of that was manufactured by other companies (convert, generator fuel pump, etc.).
Jayco's JRide system is nice. Our motorhome, from the factory, handles great compared to some of the horror stories I've read on this forum. Add a 2 year warranty to the mix and I think Jayco makes a nice motorhome.
I would agree with sullivanclan, there are higher end units, but I think there are a lot more that are beneath Jayco than above Jayco.
