The best electric fan IMO is from a 90's taurus. I have one in my ranger they come with a shroud attached and are 2 speeds so if you off road you can wire up high speed to a switch for when your stuck in the mud and spinning your tires.
As far as tailgate removal, it definitely varies model to model. My ranger gets about 2 mpg better without the tailgate but my 2011 Tacoma gets about a little less than 1mpg worse. Also, one of the best aero mods IMO that you can do to a truck is an underbelly tray. Cars, generally speaking, are mostly flat underneath due to there uni-body construction whereas trucks have a full frame so the floor pans are atleast 6 inches above the frame and the beds are even farther up while the axles, exhaust, spare tire, cross members, drivetrain, etc. hang down all producing drag. When I put my ranger back on the road it's one of the first things I'm going to do to it plus depending on what material you use they can be free or close to it
