Michael,
if you have a first generation 2017 to 2019 Kampa Pop Air and a post 2010 van you are advised to trim 80mm off the ends of the awning cord.
If you have an earlier van or second generation 2019 onwards awning you do not need to do anything.
The second generation has a removeable side, zip along the front edge of the roof for optional canopy and extended ends at awning cord.
