As Teacher's Pet stated, we have a 4-slide Phaeton, but a year and a half ago, we purchased a 24 foot B+ with no slides to take to Alaska. We completed an 11,000+ journey there and back this past summer. Was it tight? Yep. But the tradeoffs were worth it. Easy to maneuver, small enough to fit almost anywhere, no drafts, etc. Heck, you could heat the interior with a match. We used our propane furnace THREE times and that was when we were boondocking. The rest of the time we used a small Lasko space heater. We have now added two Scotties to the mix and that will be a greater challenge, but we still love it.
We decided to keep the "wee" one and use it for travel when we go to the east coast and other places that will be more convenient with a small coach.
Different strokes for different folks. We love the convenience of no slides and it works well in certain applications.
