Condensation!

[Bossman Bluey]

I am looking for some advice.
just popped outctovthe MH to check all is ok and noticed what appears to be a condensation line on the inside ceiling it appears to be following the foof supports,
firstly should this happen?
up until now MH has been dry
is it due to the extreme cold weather?
would a cover help as I was thinking of pur chasing one , that said we have sat dish and AC on the roof would an off the shelf still fit or would it cause potential pooling areas?
any advice would be welcome .

Are you heating the inside of your motorhome? If so stop, it will cause condensation

Hi
no I haven't used any heating , I live in devon so we have plenty of rain and no issues .
It seems only this recent cold snap has brought this problem

Went in ours yesterday, fully drained down, emptied and heating off since October/November. Panel was showing 3 degrees, dry as a bone.

I have a feeling this wouldn’t have been the case had I left the heating ticking over.
