looking for shortest possible bunkhouse with slides

I have a 2010 Rockwood 8281 SS that has two slides, one for the rear bunkhouse. Bunkhouse has a queen futon sofa and a single bunk over. There is also a 1/2 bath. U-shaped dinette. The newer model is 8281WS that has the same, but added a wardrobe slide in the master. I know Rockwood is not exactly top of the line, but we are just finishing 4 seasons with no problems other than a slide motor giving out last year. I have twin 12 year old daughters and a 14 year old son. And a small dog. Has served us well.
