Have been RVing for over 45 years, and once we got one with a slide, I understood the appeal. We will NEVER get another rig without at least one! Even had a pop-up with a slide out kitchen area! Other suggestions are spot on about being certain you can access everywhere when slide is in! Some rigs close up and bathroom/bedroom/fridge are no longer in play. We have only twice had a problem with slide not working properly in over 20 years and several different RVs. The extra interior room is wonderful - and would be great for extended family or friends. Very easy to operate, just be certain rig is level before opening or closing.
