Just thinking,for those hot days here is an idea. Take the auxillary fan and wire it to a toggle switch in the cab so you turn it on when you wish, instead of the sensor doing it. I don't think it would be any real benifit but it might be a fun idea. random thoughts, gotta love'em. Also on the subject of cooling, has anyone here had exsperiance with after market electric replacemnts to get rid of the engine driven one? How well do they work, problems ect.
