Well, back to the drawing board. Went to a dealer that had a 300DS and a 300TS on the lot to do physical walk thru / comparison. I could not stand in the shower without hitting the roof and could not move my arms much with the shower door closed. Not too happy with that. Then sat in the drivers seat. Felt like I was in a kids car. Figured out that the seat base is mounted closer to the front of the cab if equipped with the swivel seat option. Sat in a Lexington that did not have the swivel seat option, and was able to adjust front to back comfortably. The Lexington had the same problem with the lack of room in the shower and, at least this one, had serious fit and finish issues both inside and out. Very disappointed overall. The search continues.
