Alfa Gold has a new model, the 3905SH out that has a layout much more similar to "couples trailers" layouts with their "Side Hauler" concept. It basically gives you a utility room that they have 3 different configurations for (bunkhouse for kids, motorcycle storage with garage door, or just an open storage room).
The price tag is way up there $$$.
Here it is for the bunkhouse:
This is one the neatest floor plans that I've seen. Reminds me of the center bunkhouse model that someone else had. The biggest killer is it is missing an outdoor kitchen and I can't imagine how they might integrate one.
