Mmm, that would be my immediate concern.I have internal ones which i used this year and not really happy with them as there was quiet a bit of condensation inside, so I'm going to try the external one.
I still have the silvercreen off the T5 and your right you havet to dry it off first before putting it awayMy issue with external ones - they get mucky and have to be packed up wet.
I'd rather get a heated windscreen.
Only takes a minute to blast away condensation.
Think i would rather dry the silverscreen than have moisture in the van, thats if you don't get condensation with the external one?I still have the silvercreen off the T5 and your right you have to dry it off first before putting it away
