How recently was the Atwood installed? Is it a replacement unit?
The reason I ask is that when I installed my Atwood I discovered that the holes for the mounting bolts are outside the lip that is formed at the top of the opening. That lip serves as a dam for blocking the water from the a/c.

Holes for the mount must be drilled outside that dam. If there is any leak from the pan, around those screws, the water will run down them to the inside.

The seal sits outside the dam and will hold back any moisture that drains outside of it, but if there is a passage through the pan inside the seal, there is no other place for it to go.

Check my photos for my install.
