When we were looking at 5th wheels and trailers, I felt like the build quality was pretty much the same between Forest River, Keystone and Dutchmen. I would say that these three manufacturers are in the same price range. We decided on our Cougar based on the floorplan and dealer. With all of our research, a good dealer is probably more important than the manufacturer.
We have friends who are on their second Keystone product and have loved both. That helped in our decision making.
Are you unhappy with your Cougar?
