RV Repair: rv thermostat upgrade, auto fan, independantly

Question
I have a new Dutchmen Kodiak trailer with an Advent a/c system.I don't like the way it works as there is no on-auto fan swich like Dometic uses.When the a/c cools down to the set temp it shuts off both the compressor and fan.Can this be fixed with just a thermostat upgrade? Any suggestions... Thanks

Answer
I am not sure if your Advent uses a circuit board to control everything, or if you are able to take control of the fan and compressor independantly.  Like you, I would put attempt to put in an upgraded thermostat.  It is just a matter of how much rewiring and bypassing it takes.  So to answer your question...I am not sure how your system is designed, but anything can be done.  Good Luck
