The slides have been and will continue to be an issue on many units....class c’’s, class a’s, and tow behinds. There are some units that have minimal to zero issues with slides, while with others it’s a continuing problem. Slide issues or non-issues are a product of engineering design and the quality of materials that the manufacturer puts into their units. We have had 5th wheels (only one manufacture) dating back to 1990....with zero issues. Our present Class C has a slide, which we rarely use. If we stop for just a “one night stand”.....we don’t use the slide. If we’re gonna remain for multiple days, we use the slide....as it creates much more comfortable living space. If we have grandkids or other folks with us.....the slide is a “huge” plus! memtb
