I visited my dealer the other day. They had another 2017 Hideout, different model but with 3 slides, there. All six ends of the slides were like mine. The dealer says that's the way they are constructed. A few other brands had similar bulging in their sides but different material. I did see another Hideout, manufactured in April, 2017 (MY 2018?) that had a different type of material on the slide ends that didn't seem to show the curvature as much but was not bonded to the frame behind either. I'm thinking Keystone used one material in 2016 production then changed to something slightly heavier this year.
