I used the Center Point system for either 2 or 3 seasons, can't remember for sure, but they do work. Also had mine plumbed separately. Last fall we went to Elkhart and had the MorRyde IS installed. We changed for reasons other than the ride. I had the tech at MorRyde remove the Center Points and put them in my truck. They now reside in my storage area. I tend to keep things but probably need to think about finding a new home for them one of these days.
