Hi Linda welcome to the MOC.
I dont have a 2950 RK but this is MY opuion (spelled wrong).
A rear kitchen to me seems that the china would be out of the cabinets on a good dip in the road. I had a trailer with a rear bedroom and closets with the clothes always on the cabinet floor when we arrived at our destination.
I believe that a center kitchen over the wheels seem to have less movement in the china closet.
Good luck on your search.
