Thanks for the reply Daniel. That was the first thing I checked by removing the Inspection Panel. It was completely dry under there. So that is why I know it is the Doors. It appears that the slots in the bottom track are not big or long enough to let the Water drain. Maybe there should be some kind of shield that would help keep the Water from just running down the Shower Door and into the Door Track which then overflows onto the Floor. The only other option I can think of is to use a Shower Curtain but then that defeats the purpose of having Glass Shower Door. Since the motorhome is at the Dealer for Generator Modification do to Overheating, we will see if they can figure this one out also. Not a very happy person with my Terra 31C. Everytime we go somewhere in it something else happens. Hope we can get things fix so I don't have to let the motorhome stay at the Dealership for repair everytime it is used.
