Josh - your AC compressor is right in front of the engine (between the radiator and the engine) - Unless I have a one-of-a-kind TCH, there is no belt to the compressor - only an electric motor.
2mpg is substantial - even more than I observed in our Honda Civic when I tested FE AC on vs AC off. I was able to get only 1mpg better FE on a 500 mile trip with running FAN only (no AC compressor - wire disconnected)..

Never argue with an idiot, they'll drag you down to their level and beat you with experience!
