Interior condensation on windscreen

I am quite sure that this time of year, you fellow motorhomers will have the same experience as me which does drive me mad!

On a morning now the temperature has changed when the interior silver screens are folded back to their travel postion there is a heavy condensation on the inside of the screen, I do not use exterior silver screens.

I combat this by way of a towel on the dash and a flexi blade that clears it but deposits a good quanitity of water on the towel, possibly into the air vents?

How do you get around this or should I just get up later, this is my third motorhome and something I should really have sorted by now, your comments would be appreciated and forgive me if this is something that has been discussed,

Happy travels,  Pete
