As the owner of a GD 2150, I would recommend the Creekside. Over the years we have owned countless RV's mostly 5ers and Travel Trailers, and I've never experienced as many problems with a slide as I have with this GD. Only slide I've ever had to extend and retract fully or it goes out of alignment (2 independent motors). Also the slide mechanism in both mine and Lipperts opinion is to light to carry the depth and weight of the slide. I do have to say GD's customer service is excellent though and we do love the floorplan of the 2150.
