Have you had a chance to visit these units in person or are simply viewing them online? When you ask; "Which one?", are you feeling those two units are so close a match that you are having trouble deciding? I don't own either one, so I can't speak from an ownership point of view, but I have a few dealers near me that have those models on their lots. I can take a look and create an opinion if you feel that may help you with your decision.
I own a Kimberley Kamper and have truly enjoyed it for more than 10 years. Great product. We have towed it from California to Montana, up through Canada and onwards to Alaska. I understand the need to pick the right product and model.
