In the mean time, did you see this gentleman's videos. Here is a short walk through of the 16', layout 4. He does a nice job of showing how small the side bath is in this layout. Not knocking it, but puts it into perspective, so you understand how tight it is. It will be fine for me, I have one on order. I like the bigger counter space of this layout, having potentially two beds, and potential full-time sitting area.
