Okay, back to the window fan in the ody sunroof..
Transom is the result of a complete re-imagining of what a window fan should be. The air chamber abundantly draws fresh air from the outside in - or reverses electronically to exhaust stale air out. Powerful

Picked that up and we are in a heatwave in SoCal so went right to work. Found a way to put it in thats perfect, almost all of it stays inside and its tilted at an angle so air moves to the rear.
I used 2" aluminum angle, with gorilla mounting tape and a half dozen ss 1/8" pop rivets on each side.
I have a couple of minor tweaks for the mount like contouring the top of the front bracket and adding a small 1/2" angle but its pretty secure.
So this vornado transom... Well compared to a good quality dual axial fan unit, its output is weak. But the last one of those I had used over 65 watts on high, this uses 25 watts, I currently power it with a jackery 880.. Its also whisper quiet compared to traditional window fans. And you only have to open the sunroof 4-5", and they cant steal it if they tried. With dual window fans the roof has to be wide open and can be just lifted out. And its easier for bugs and leaves to get in.
This is touted as weatherproof, and theres a powered rotating door for the reversing feature that also closes automatically when you power it off. It doesnt fully seal the outside air but seals out peeping toms. Theres a remote control but theres panel controls too.
These are $100 btw, and they also make it in black if you want a heater instead.
All in all Id be happier with more output but given the positives which are related to that, this was the best choice. If it were for a home Id have taken it back.
I still have 3 small working portable air conditioners in storage, by next summer I should be caught up enough on getting the electrical stuff in like my 07 was and Ill have one of those in for the hot months.
