Escape Hatch Condensation

Our 2002 Lance 811 has the crank-up hatch over the bed that also has the quick-release as an escape hatch. With cool weather outside, the aluminum frame produces condensation like crazy, to the point where it drips on the bed.

The factory did provide an insulated vinyl cover that snaps to the ceiling around the hatch. The problem is it doesn't form an air tight seal to the ceiling, so condensation still forms and just puddles on the top of the vinyl cover.

Obviously what's needed is a way to stop the inside air from contacting the aluminum frame of the hatch. I thought about spraying some of that Flex Seal liquid rubber on the exposed aluminum but not sure if that would insulate it enough.

What have you guys figured out for this?
  • Dog's recommendation is a last resort problem solver IMO.
  • cut a square of Styrofoam to fit tight into opening.
    Better yet, you can buy polyurethane boards at HD with foil on both sides. Put some masking tapes on the edges to prevent scratching the foam.
  • What I did and it did not cure the condensation completely it did lessen it some what. I went to HD and bought a roll of the foil backed foam pipe insulation. I cut it to fit. Now it does eliminate light transmission but that doesn't bother me.Then I using the snap cover I put some insulation in the opening held up by the snap cover.
