Jerry, if you look up and to the right in the right rear wheel well you will see the access plate under the shower drain. The floor is cut out to allow for the drain, I think they cut a little to much! My idea is to cut a couple of pieces of wood that would fit around the drain similar to the old time stocks people had their heads locked in.
Not going to be able to do anything until next spring. Getting ready to move in a week, by the time we get settled I will be cold in Indiana, can't park the coach at the house so it will have to go in to storage
