Floor plan: Front Bathroom, Middle Kitchen, Rear Lounge

The front of the trailer is typically angled quite a bit, eliminating standing room. Probably the main reason you don't see that floor plan. Oliver's have a front bathroom but no slides and they aren't cheap. There are some models out there that the front stays vertical but come to a point on the tongue. I think they call them V-nose. I've seen at least one of those with a bathroom at the front. They may not be made anymore either.
