The door catch is a very important element of the thermal management for Brunnhide. For me the best way to keep the camper cool is to first try passive ventilation. If more help is needed try a solution that does not consume a lot of energy. In Brunnhide the skylight in the bathroom is the most important part of the ventilation. I rely on it when parked and camping. Depends on the weather I would leave it open in one of the three positions. The skylight sometimes is used in conjunction with the low power ventilation fan or just by natural cross ventilation with the other windows or the sliding door.
When I have a need for a solution in this compact camper I seldom turn to the RV products. To me most of these products are overpriced, poorly designed and absolute crap in quality. For instance, a RV-ready plastic wine glass for $7 plus shipping. I can buy a crystal one for crying out loud. I can buy a 6 wine glasses from Ikea for less.

the fully open position.While I won't willfully do, it is relatively safe when the vehicle is in motion.
no drilling required - it take advantage of the door latch
door catch for keeping the door open just a crack
I have been wanting to refine this such that it works regardless on how the vehicle is parked. Here is a prototype made of cardboard.
some elbow grease
when not in use it does not impede the door's operation.
there is no need to turn the door knob to use the door catch - when the door is open hello kitty is sideways

fixed the diesel leak on top of the filter - it has plagued me ever since i own brunnhilde; i wonder if I would see the slight improvement on fuel mileage
