Camper ventilation tips/mods for dogs?

My German Shepherd and Husky ride in the bed of my truck and they sleep down there while camping. I currently contain them in my snugtop with all the vents open and I was wondering if anyone has any ventilation tips/ mods for keeping them cool both while driving and camped out? I’ve thought about putting in a few vents, but I haven’t seen anyone do that aside of the ceiling tent fans.

Thanks!

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

Thanks for the link :+1:
