The bathroom on the passenger side opposite the refrigerator is a fatal design flaw in my opinion. Something has to give in dimensions. A Sprinter is basically 70" wide. A decent bathroom should be at least 26" wall to out and a refrigerator needs 24". That leaves you a 22" aisle at the very best. To overcome that narrowness you have to sacrifice the functionality of the bathroom with expandable doors on an already too narrow bathroom or expand bathroom/showers into the aisle. Those are both tricks Roadtrek employs. I've measured some models with aisle dimensions down to 18-19" which is hardly wide enough for one person unless they turn sideways. I could go on and on about functionality but the dimensions are the big ones.
