To vent or not?

[Greenie]

In our PVC there are vents beneath cupboards and drawers in various sections of the floor. As the motorhome is ‘laid up’ for the next few months with an insulated screen cover and an internal small heater set on a thermostat I have, in the past, opened said cupboards etc to enable an air flow in.
Do the experts concur with this or, is it better to leave them closed thus reducing fresh air from entering? My concern obviously is condensation occurring.
TIA

The reason you’ll get condensation is because you’ll have a heater in there, just leave all cupboards open and let the air flow, screen cover will help… take out some soft furnishings if you wish…

Thanks JS for your reply.
The small heater is there to prevent the small amount of condensation that invariably occurs on the windscreen from 'attacking' the seat bag warning module within the floor. It has happened twice over time and, as many of us know, it's a costly business to avoid the dreaded MoT failure!
