Just a personal opinion.... The Physics are bad.
Just about any good tent has to "breath" to a degree. So let's imagine what would happen in FL with an air conditioned tent, with no insulation....
The interior temp would drop. The tent is "semi-permeable" (it breathes). Water vapor would likely start to condense on the interior tent walls....
Now, a unit like this COULD work if it also de-humidified. But I'm just guessing that if it did not? You would end up with a pretty significant rainstorm INSIDE the tent.
