The dreaded Swift crack.

They were definitely on Lunar caravans and probably most other brands. Generally it was a small transparent sticker at bottom of the window with black type on it and a little diagram. The next time you go to your caravan have a careful look.

Obviously removed as a cost-saving measure by the time I bought my Lunar!

On first looking at the sticker I thought - surely they don't mean keep the windows shut if it's sunny?? No way would the OH stand for that!

It then dawned on me that those were probably meant to show moving vehicle streamlines.....

The meaning is, Keep windows closed whilst towing caravan. But how many do you see with the roof vents still open whilst travelling.

Our Lunar was a 2011. They were also on our 2018 Elddis.

We saw a caravan roof open coming back from Blackpool on the M55 when we away one week ago.

Just checked all the Polyplastic windows and others skylights on our Bailey 2009 Wyoming. No stickers nor anything in the handbook.
We have both types of blind, roller and concertina.
I suspect Polyplastic had numerous problems circa 2010 which may explain why they and Swift etc are using the stickers

For all we know Polyplastic may have changed the formula or production method.

One for investigation or lets have more Punch and Judy whilst Border Billy munches his popcorn 🤪🤪
