Yes, your expecting too much depending on the conditions. The fan only moves what is outside, inside. And the initial massive heat buildup inside, to the outside… It does however do that very well. The question is, is it any better outside???
On those nasty very hot & humid “days”, dehumidification is the need. Either a stand alone dehumidifier or an AC unit. If you where out west in say AZ, Phoenix area etc, in that high heat, low humidity, swamp coolers (sprays mist of water into a fan) on the roof of the houses helps. They get the evaporative cooling effect. However they are bone dry, massive high heat. Opposite problem of us east coasters with high heat and high humidity.
If you have ever had a “whole house” fan, the kind that draws air from the living area of the house and then exhausts it out through the attic, that type of action is what the Turbo Maxx or any of the RV power fans , Fantastic etc, do. They help get the hot heat inside the camper out, and then bring in air from the outside that is “ideally” cooler.
We use to be in an older farm house with no AC in upper NY. The last week of July/1st week of August was always brutal. 95 to sometimes over 100F during the day and the humidity was on overload…. I finally installed a whole house fan, about a 3 foot blade tip diameter fan and come after supper or better about 8:00/9:00PM, turn on the fan. The 1st thing it would do is exhaust the massive heat built up in the attic, then it would draw in cooler air from the down stairs windows (2 story home) and it was bearable.
Our Turbo Maxx falls into the same category. When we go boondocking this is how we survive those again hot summer nights. If folks are comparing those hot nights to not having a fan, then yes it a very large improvement. During the day, there may be a slight improvement but again depending on what is outside, may not feel a whole lot better.
