We are on our 2nd Cougar and it seems that quality has improved a bit. Although the weight is about the same between the two, the suspension and tires are much better. Some of the "improvements", like the remote controlled switchboard, are ill-conceived and poorly executed. The floor decking and some other structural things seem to be improved (we took the factory tour). We have a kitchen sink that is developing pits in the finish and will need to be replaced some day. We still have a few repair issues after each trip but am starting to think that some of that is normal for something that bounces down the road a lot. Many of the repairs are for things like the cabinetry, appliances and furniture which are not necessarily model-specific, so I'm not sure if a high-end model within the Keystone line might have many of those same problems. It seems that Keystone uses the same "parts drawer" across many models.
