Moisture in fiberglass cap on over the cab bed

[lbyeary]

Has anyone had a problem with condensation forming inside the fiberglass cap on the over the cab bed? The moisture drips down on the shade and then drip onto the bed.

Are you sure it is condensation and not water leak? The marker lights on the top of these units sometimes fail and allow water into the cap, it then travels until it can find somewhere to come out. Since these are laminated with compressed layers, the actual point of entry can be some distance from where it shows up. Also check the seam between the front cap and the main roof make sure you dont have any issues on that seam.

If you are sure it is condensation, it can again be caused from a water leak as the water will conduct heat and can freeze or stay cold thus allowing the surface to condense. do you have any condensation on windows or doors? Not sure what temperatures you are experiencing or how many people are in the unit. This can also occur if you are not venting the moisture from cooking, breathing, showering ect.
