Condensation!! Advice please.

I have a 55 reg Autocruise Stardream. Inside cupboards and on the rear internal corners are aluminium strips which I assume are cosmetic only. This is my first Motorhome, and I have noticed during cooler periods when we have the heating on, there is a lot of condesation on these panels. Can anyone offer suggestions as to what I could do to aleviate this problem? The condensation is so bad that if we don't keep wiping it, it runs down the panels and dampens the cushions.

Regards

Peter
