Hi Fred,
How did the room close after you installed the 1/8" plates on the bottom of the room? If you want to lower the room, make small adjustments. Before you move anything, index and mark the outrigger brackets where they attach to the room. Jack up and support the room front and rear. Raise the mount 1/8" at the wall mount attachment points. Run the room in and out several times to realign. Hope this helps, Fred
