It's a 2006 Ford F-150 with the 4.2L V6 & manual 5-speed rated at ~200hp. I think curb weight is ~4600 lbs. I'm assuming that the radiator is the same as in the 5.4L V8, so I should have some extra capacity there. The EPA numbers are 14/19, I've been getting 14.5 with pure in-town (and that's with the engine hardly ever warmed up all the way - I have short drives with no (!!!) bike lanes) and 17-18 hwy - probably mostly because we were driving 75 with a camper shell. We'll see where I can get as I start some mods, and can afford an aerolid.

As for now, the fan is out, and I'm going to start a bit of test driving without any fan to see how it goes before buying electrics. I'm leaning towards a pair of 14" Derale Tornados - $150 cheaper than the Troyer set-up.
