Let me offer a counter part against slides, my wife and I bought a small class A (2002 Safari Trek 28 ft) motorhome last year to travel in, not to just go to one place and park it for weeks or more at a time. Without slides to worry about, we can stop in a camp ground for the night, plug the electric cord, lower the leveling jacks if needed and be set up for the night in 5 minutes, the next morning reverse the process and be on the road, dumping and refilling tanks every 2-3 days as needed. Also on almost every layout I have seen slides either must be out for the the floorplan to function, I have seen layouts where it is even impossible to get into the bathroom with the slides in, as well as many where the mattress on the bed must fold in half for the slide come in. So much for pulling off at a picturesque roadside pullout overlooking a river for a bite of lunch and maybe a short afternoon nap in one of these, before hitting the road for the last 150 miles of the day. Alternatively there are the slide models that are functional with the slides in, and what you get with the slides out is just more floor space. Then there are the very few allow function with the slides in, and gain more than just floor space with the slides out, these tend to have seating or counters that can extend when the slides are open, and fold in on themselves when the slides are in, but again even this increases the time it takes to break camp. Being only 28 feet long we can easily fit into places where we can find a pair of 2 parking spaces end to end, and with a 178 inch wheel base we can even back into some standard parking spaces and let the tail overhang the curb. Now sure we can't fit in everywhere, we are certainly not going to try to go through the drive thru at a McDonalds, but when traveling along and we see a sign with claims of having the best food in the state 4 miles ahead, there is a fair chance we could stop in and give it a try, try doing that in a 45 ft diesel pusher pulling a toad.
