Mile High, my basement access is under the slides too (like many Class A's) and what I do to avoid having to dip under the slides as much as possible is the last thing I do when setting up is open the slides, and the first thing I do when getting ready to leave is close them. Once I'm level and have the power and water and sewer hooked up, I drag out all the chairs and whatever else is under there that I'll need and then open the slides. When leaving close them up before putting everything away. Makes life so much easier.
