I purchased these (see link below) and had them installed in my trailer along with a separate battery so I don’t have to worry about draining the batteries in my truck. I’m in VA and show in the summer heat and my horse is never sweaty! I think the total cost ended up being around $300 to have them installed. (Guessing since I had some other work done at the same time)

To be clear I am not “picking” on your comment using it because it provided a link to a fan that really isn’t going to do much for the horse.
The numbers don’t lie, as I said in my comment above. These can “move” at best 100 CFM of air. Which is why it is hard to find a retailer that provides the specs. The one in the link doesn’t.
Nor does this one which is pretty much the same fan for almost $20 less.

Where as this one does, a respectable 270 CFM set on high. But it doesn’t give the deminstions

IMO if they don’t give a “performance number” they are worth buying. I bought a trailer with 2 of the small one in. it The type you see in lots of trailers. I stood were the horse would be standing and they made little to no difference in a hot trailer. But at least they had the “feel good” look to them.
People buy cars based on gas millage a number given by the manufacture. Not by asking the seller and the seller saying, “it gets good mileage”. OK, but what’s the number?
The fan I linked to has the ability to move over 900 CFM of air. 9 times more powerful than those little fans. That is a big difference. 4+ times more than than the second one I linked to in this comment.
And it is only 13" by 13 inches. It cost the same to wire any fan. So might as well do the research and install ones that will do the job intended not just for a “feel good” look.
