If the outside temperatures are below freezing, that air will be extremely dry as virtually all of the moisture will have already condensed out - no need for the air conditioner to dehumidify that air, it's being done my mother nature already.
The volume inside the Rav is pretty small if you have wet stuff and one or more folks breathing in there. Warming the interior without exhausting all the extra moisture via turning off the recirculating function will quickly make a mini sauna inside!
Even when it's raining and warm outside, I find the defog always works better with recirculate turned off, with or without the air turned on.
