Hi guys, I’m a bit OCD but just noticed this week after nearly 2 years of ownership my all seasons conversion roof is in colder weather showing a small lump which is the front edge of the gps aerial underneath. I’m aware some converters relocate this or make a higher recess on the roof to allow for it. Has anyone else had this with their van? Are these roofs prone to big expansion when warm as it looks to me like it disappears when the roof is hot in sunlight! Maybe I’m just being too fussy!
