Sadly I don't think you are going to get a ton of feedback (or any at all). The Winnie 5ers are a rare breed still. As noted in another thread I have the '17 28sgs. Overall very happy with it. The issues I have with it seem to be common across the market. Whoever designs the interiors must never go camping. (Storage spaces that are out of reach of anyone under 6-3, other odd design choices.)
Minor complaints like this aside, we took a trip over roughly 8 weeks, VA to Calif and back with lots of stops in between. The rig towed very nicely. Stable in winds and I did not even notice semi's passing at freeway speeds. Our prior rv was a Pace Arrow 37 foot Class A. I felt every wind gust, every truck, every pot hole. Towing this 5er was a totally different experience. I just need to get better at backing.
