I am a newby; last year I'd bought a 24' Keystone Bullet with bunks, decided I didn't like the floor plan, so traded it in this year for a Forest River EVO 26' with rear living. It has one slide where the kitchenette is, with a couch in the back (or two optional chairs). I LOVE it! You have more light from the big back window, and someplace to sit and watch tv other than at the table. It has a step in shower with glass doors and separate toilet (a taller one, which we older folks need!). Total length is 29 1/2 feet. The bedroom is separate with a door for privacy. I can tow it with my 2016 Silverado 1/2 ton with hd tow package. This is the only one I looked at with rear living, but I'm sure there are lots of manufacturers out there. Mine has nicer quality stuff than the Keystone. Electric stabilizer jacks, better cupboards, Corian countertop, under mount sink. Good luck.
