I had a Lance 1030 with no slides. When I sat in the Arctic Fox 990 with the slide out, it felt twice as big. I loved it. That being said, I do like the convenience of no slide for quick restroom breaks while on the road, making lunch, etc.
I have a 5th wheel with 3 slides. I have never had an issue with any of them in almost 10 years of use. I don't worry about that. But having to open and close a slide is certainly something that does take a small amount of time and thought, no matter how "quick" it opens.
