I, too, am a bit dubious about slides, especially in small trailers. They do open up the space, but in some that I've toured at the shows, it's impossible, or extremely difficult,to get to the bathroom or the bed unless the slide is deployed.
One of the many nice things about our "slide-free" eggs is minimal maintenance, and easy setup. I consider the area under the awning
to be our "easy maintenance" slide-out area. I slide out there and sit down... and enjoy the outdoors around me.
Of course, when it's inclement weather, a slide has certain appeal.
