New GMC owner & 1st post!

Last Oct. we attended our 1st GMC rally with the Western States at Emerald
Desert RV in Palm Desert. The temp was in the 100's plus high humidity.
Well our Duo-Therm Penguin roof AC was producing so much condensed water
that it started leaking inside. We had to scramble to find enough pots &
pans to contain the down pour. I found the PO had put at least 2 tubes of
silicone caulk all around the base of the AC & the roof indicating a
previous problem. I peeled off some caulking figuring that it was actually
trapping water inside but it was too difficult to get much off. What little
came off let some water out but it still leaked inside. Needless to say it
interfered with an otherwise great time.

I am now tackling the problem at home (finally). I see that the roof gasket
is fully compressed which is hopefully the root cause. I will clean off the
caulk best I can, try to find where the water is supposed to drain & make
sure it is not blocked and install a new roof gasket.

Has anyone else had a similar problem and how did you correct it? Is there
anything else I should look for?

Thanks
