I'm glad someone has asked that question as i was always a bit puzzled about the gap, i'd like to know what people use to fill the gap and where to get it?
Also why have some vans got this gap and some haven't??
My van wa converted by Bilbos and it has a fibreglass moulded 'frame' around the window which bridges the gap. My brother fitted some to his van last year, he bought them from flea bay for another vehicle then chopped em down and re-stuck them with fibreglass on the inner side. once it was covered with carpet your none the wiser. It stops a lot of draughts behind the units. sorry I cant be of any help about sourcing the materials.
