Hello Everyone, I need to replace the skylight window blind on my 2010 Bessacarr E520. It is a low-profile motorhome with a window in the roof at the front above the driver cab. Firstly does anyone know how to remove the blind and secondly does anyone know where to get a replacement. The window is a non-opener. Thank you any information will be gratefully accepted as fairly new to this but enjoying every minute.
