Is there performance history/data available for T300 between -20 and -40 degrees C?

Has anyone got any performance history for the T300 AP below -20 deg C (-4 deg F)?  How badly do the range and other parameters drop off below the -20 deg C spec?
Have a possible application that needs operation during winter in Minnesota.

From what I am told, there is no heater and the units will not restart below -20 F. Use the more expensive 7782 (rated to -40F) or hold out for the new ac enabled version of the original 7782 which will likely have the heater.
