Are we talking about a combo W/D or stackable units? The BH3670 layout is similar to the Augusta, but the floor plans were changed between the 2009 and 2010 models (BH3670, at least) to rotate the W/D area so it faces into the bedroom rather than into the closet. The space now looks like a stackable "might" fit in there. In mine, only a combo unit works.
But, for our use, I open the Gray #1 drain when running a load. The Splendide combo can easily handle a load of bedding or two sets of towels, or socks/t-shirts/undies, up to 11 lbs. Stuff does come out wrinkled, however, but I just smooth it out by hand, fold, and don't really worry about it. (Yes, I do my own laundry. Force of habit from the days in the barracks.) I figure if the places I go to spend money while camping are upset with some wrinkles in my T-shirt, they may be also upset with the wrinkles in my money. So I won't give them any.
