I am one who did not have them then got them and now this next coach that I have ordered will not have any. The slide steals storage space for a bit of extra walkway. Sure some layouts let you have a east west bed in a slide but everything is a compromise. I rather be solid and no slide issues and the benefit id when traveling you are home still. I am going smaller now but if I went back to a class A I would either order a coach without one or go with a super c without one. I have had them for ten years and did not have them for 7 and decided that I rathe r not have any.
