External sun visor

[Treecol]

Hello Funsters I have searched online and on the forum but can't find a sunvisor. Our MH is 2004 Rapido on a Fiat Ducato and they do one for the van but obviously the coach built part of the MH would prevent it from fitting.
The reason for wanting one is because when it rains we get horrid white streaks down the windscreen as per photo.
Has anyone found one that will fit?

Not sure you can get them in the UK, but these look quite good and easy install/remove https://www.rvmasters.se/sv-SE Plan to get a set ourselves for next season (sun visor ones)..
