I have owned a cardinal by forest river for three years(bought it new) and have been very pleased. There are trailers that have nicer trim and amenities but for the money I don't think you can beat the quality. I would purchase again.
We have a 36RLTS Cardinal and love it. The RLTS stands for Rear Living, Triple Slide. It has dual air conditioners and a Kenmore stacked washer & dryer. Some may be more expensive and have more dinging bells and flashing lights but I don't think we could have gotten more bang for our bucks. We broke it down to two brands and bought the Cardinal over a Montana. JMHO Good luck in what you buy and have fun.
We have a 319BH Montana Mountaineer and we love it. I've never heard a bad word about the Cardinals either. We ended up picking up the Mountaineer based on floor plan. We wanted a fully enclosed bathroom/shower and a bunk house. Good luck. I'm sure either will do well for you!
