I think you will find anything built on the same freightliner chassis will have the def in the same location. It gets filled every couple of tanks of fuel I use a pump to put def in the tank and use a separate container to fill at the pumps. No big deal. Do I wish they put the fill on the driver side hell yes. Is it a reason to get rid of the coach no way. I hear the the Berk with the tag axle may have the def fill on the left side.
