Derek,
The problem is not the insulation/condensation, but in all probability
the lack of a vapor barrier. The vinyl facing works, but if the edges
are not sealed, instant condensation. Try vinyl or duct taping the inner
lip of the doors to the vinyl facing, which should keep the moisture on
the outside.
Remember that when you raise the cold outside face into the heated
ceiling, you'll still get condensation on the face, which will run over
the edge and drip down.
