To be a "hybrid" the trailer has to have some canvas, whether it be just 1 bunkend or 3. An "expandable" does not need canvas, but would have either the rear slide or something like the Trailmanor. If you're looking at a camper without canvas, it's not truly a hybrid. Many campers other than a standard TT are called hybrids, but don't meet the requirements of the canvas. For whatever reason, a TT with a side slide that has the dinette or other is just considered a TT with a slide. Makes no sense, but that's the distinction. We just made the change from our ROO 23SS hybrid to a TT with a side slide and love it, although miss the feeling of the openness of the unzipped canvas and sleeping under canvas. Don't know why there seems to be a sense of steering clear of a rear slide because they can be just the perfect thing for many. Hope you can find the perfect one for you.
