Question When cooking

Interested in the Dandy Dart but worried the PVC roof will become damp with condensation, is this an issue?

I find cindensation is a problem with my Dandy Designer over night, I have fitted thin insulation beneath the mattresses and over the ply on the outside of the bedding area. I have also purchased some cristal moisture absorbent thingy from Home Base for this season. We ran our electric cool box outside last year but it took a lot of water in overnight so this year we thought we could run it inside to help with the condensation and add some sort of tray to catch the moisture....try anything once
