Electric or Propane?
I have an electric and have moved it in and out to repair a slow leak with the ice maker water line. Straight forward - remove screws and brackets I built a step/stand that was the same height as the base. Rolled right out. Most likely you will need to take doors off also so you can get out all the way into the hallway. Once this is done, you can slide towards the front or back of the coach to gain better access.
