I think it has to do with your personal use of your rig. If it is a single person, maybe a couple going with no slide might be just fine. Also depends on how much time you spend inside, versus outside. Our Jayco has one slide, we like the additional space for friends or grandkids. But if it is just the two of us we could go without. Our's works manually as well. It doesn't obstruct the bathroom door or anything. Matter of fact, we often travel and don't open it overnight unless we are staying longer. Ours secures with braces so the slide is double locked closed. Hope that helps.
