I am thinking of doing 3 10" slimline fans... I want to use the 97 switch/sensor that reduces current/resistance at different temperatures. I want to wire that signal into 3 different relays that each open at different resistances, so that as the truck slowly heats, the fans turn on in succession. This will keep things nice and cool, and reduce cycling and abrupt temp changes. At 1000+ cfm each, I think that the 10" will work well enough that the third fan may never have occasion on trun on. Also, since they are 10" they should, reducing the issues needing a shroud for the lower portion of the fan. I wasn't sure if 3000 cfm would be enough, and I couldn't find anything when I searched... cfm ratings never came up... until the above post showed up...
Have you seen this yet?...
