We have a 2018 CL 21 RBS Platinum. We have had no problems with it other than the one I caused by turning the electric water heater on before filling the hot water tank. This burnt out the electric heater element. Very easy to replace and totally my fault. There was a recall for cracks in the frame but our unit didnt have any. We still had the work done. We have gone for full hook up camping and for complete dry camping with a generator. The CL 21 was great in both cases. I do have the benefit of a great dealer in our area. Gerton Auto Sales in Mt Vernon, Indiana. We are planning a 6,000 mile trip in May to Rocky Mountain NP then on to Yellowstone for a week. We look forward to it and have no doubt our CL will perform as expected as has up to now. In short....we love it. No rust no rot.
