Camper ventilation tips/mods for dogs?

[mode7]

Might be able to find some ideas and ask some questions on this thread.

Dog Rig (2011 Doublecab Tundra)

I was out at the end of July and ran into some rain. With the fully open panel, water runs from the hinge down the GFC frame. To she the water from the edge of the panel instead of the hinge I stole your ventilation idea, but did it a little differently. Just one length of paracord attached to the panel, then looped over 1, 2, 3 or 4 of the GFC mounting brackets depending on how open I want it to be. Seems to self balance and work ok. Secure the paracord with a bit of velcro as well. Thanks…
