Some of this is sounding a little confusing.......about those wheel wells . Are the wheel wells not inside the storage compartments that make up the seats of the larger dinette - which converts to the double bed in the 17 ? They are in the 15 , and they are some inches below the top of the seat . So I don't get where the wheel wells would be a problem , if one only took space from the sink/stove side it would be wider at that end and the fridge area would stay the same . While we might be good with that (if we were after a17) but don't expect anyone else to feel the same , just don' t get why the wheel wells would be an issue . Coarse ...I could just be in a fog .....
