Technical rear door stay/limiter

[nicbla62]

How do I stop my rear doors swinging beyond 90% in a gust of wind? Already slightly damaged rear window and bodywork. Its a 2019 Ducato converted into a campervan.

Some versions of Ducato and Doblo vans have a hinge with a lock at 90 degrees , but can allow release to swing wider for pallet loading etc.
So maybe see if you can retro fit that type.
My 2010 Doblo Maxi does. I have also had the larger vans with those locks also.
