Anybody install Perma-Cool's Cool Pack on thier truck? Looks drop in but is it worth the money?

 

I have them, but the only reason I did go with them was because they were the only fans I could get in the time I needed them. I bought them from Jegs, they shipped them overnight(I had track run scheduled that weekend and wanted a new mod). I do like them but they are pretty damn pricey.
