Kingham bed area opening window

Hi fellow Kingham owners. 

We're currently in Provence and it has (re)occurred to us that the ability to open a window in the bed area would make for a more comfortable night. The vent above the bed is fully open, but, just doesn't provide enough cool, fresh air.

I'm thinking the off-side barn door might be easier, but, I'm open to suggestions. 

Has anyone made such a change in their van?

Thanks in advance.

I have seen a post of one put in the rear door, I think it was on a Warwick. We have a maxi vent fan in the sky light over the bed, has worked for us this summer. It can be set to draw air in or take it out.

If you check back to august 15th on this section ,there is a report by little scrote on fitting an opening window in the rear door of a Boxer which may be of interest.
Good luck.

we have the same issue and were thinking of a roof vent fan, does anyone know if there is a live feed anywhere nearby?
