Hi Stephen,
We recently fitted a Caravanstore Zip to our van and find it brilliant.Easy to put up and down (easier with 2 people!)
However last Bank Holiday we encountered some strong winds on a coastal site, naturally put the awning away but the wind was lifting the awning and was banging it against the side of the van, hence a fairly sleepless night.
Next morning I inspected the van and there was no damage at all. To rectify the problem I got out the trusted gaffer tape and put 3 short strips on the awning to the side of the van.No more sleepless nights and just took off the tape when the winds ceased.
Hope this helps
Regards
Nidge
