I have looked at the Cougar and they seem to be a well made unit,have never seen the other model you mentioned though.We have a Cardinal 29 ft 5 er and we love it,this is our 3rd Cardinal so I guess you could say that we like the brand,but also part of that is we have a good dealer who will take care of warranty issues without a hassle.
The Cougar looks good and is quite comfortable. However, DO NOT overload the pantry shelves with canned food and then make a trip over "road construction" (rough) areas. Repairs will be in order. In other words the pantry shelves and the TV shelf in the livingroom could use a little reinforcement. (Solution for this: store extra canned food under dinette seats.) Great for weekend getaways. We have a 2002 31' bunkhouse model that our son loves because he has his own room. Beds are nice and comfy. Pulls great with '94 Chevy Crew Cab 6.5 turbo diesel. No other problems.
