Basrards rattle. Get Rivera sliders instead and be able to see out also.
Same with mine. If they're closed tight they seem fine.
Roadcow has em and I hate em.Have you had the opportunity to use Rivera sliders? They let more air in, seal better, don't have panes which fall out, you can drive withem open, and last of all you can see out of them!
I've got the sliders and I'll probably keep them as the louvres can't be found but I'll try the sliders for a while.
That looks like the van at the back of john whites.
