I made my own set up for about $150, I would post a pic but I havent figured out how yet! You have to ensure that the fans you select move a min of 5000 CFM, I used two 5500 CFM fans, made my own shroud and bought a 180*-205* electrically contolled thermostat with auto on for A/C. I have a 24ft toy hauler, I think 7000 empty, loaded, water, 3 250F race bikes and a 4 wheeler, maybee 10500lbs, I have never had any problems with overheating, in town loaded my temps stay @ 205*+, on the HWY they run 195*.
There is a thread with a picuture of my set up 5 pages back!

Well, like you said, you're going to need to fab up a shroud, and wire in some type of thermal switch (with AC override) like Dad did above. You'll surely need a dedicated sensor there someplace (I believe there is a spare plug in the water pump housing) but beyond that, it's up to you how & where you mount everything. To me that's the fun part of DIY stuff like this!!

You can buy a electronic thermostat at O-Riley's, Advanced or just about any auto parts store, generally around 30 bucks, Make sure you get the adjustable thermostat in the range your looking for !80-210 should be fine, Then ones I have hoooked up come with an auto on for the A/C,. You just spilce into the wire going to the A/C clutch! Hope this helps.

It is a high speed electric fan that mounts to the condenser.

Empiretc, you actually noticed a drop in EGT's with a pusher fan installed? How much? I'm wondering if this would be cost effective for me to add to my truck. Got some details. What size did you go with? Etc...Thanks Country

Guys, have you ever opened the hood on your truck when the clutch fan is engaged? Holy wind storm Batman! I can't see two 2700cfm fans competing with the OEM clutch fan engaged, this factory fan is animal. Wonder what the CFM's of the electric fans are when you put them up against three radiators?!
