Vent fans and a/c at the same time

At home we find it unnecessary in summer to run the het pumps on the own stairs level usually. We have a huge vaulted ceilign on one side and the cold a/c air sinks down, and sometimes makes it really chilly on the lowest level.
In our RVs with both heat pumps/ac running it still some times is warmer than we want.
Has anyone used one or two of their roof vent fans to pull the warmer air, that rises out of the RV found any success with that approach.
The cold a/c air sinks to the floor of course.

    agree. cold air falls but that ceiling vent fan would likely grab it before the air would reach the floor. we have two small fans running with the AC...one up front and another in the back.

  • Anone seen any benefit from running a ceiling vent fan or two, while the ac/is running in an RV? Hot air goes tot the ceiling and cold air from the ac sinks toward the floor.
