To Slide or Not

Pros and Cons as has already been mentioned. Another suggestion, if you do find a unit that you are considering with a slide, do your research on what others' experiences have been with that particular RV and it's slides. Some slide mechanism manufacturers have had a good run with their products and others on certain models have not. You cannot rely on a particular RV manufacturer producing good quality slide units year after year as they may change slide mechanism suppliers and that may change everything when it comes to reliability. Try researching Schwintek and Power Gear and you will see what I mean.
