    Has anyone ever driven a truck with one of these installed? Summer is coming and I am curious if these things work well

    Not that brand but yeah. They work well up to about 80 degrees or so I'd say, keep you pretty comfortable when it's too warm to be really comfortable inside the truck but not too hot.

    80-90 they keep things tolerable, but maybe not so comfortable.

    Up above that they turn hot a miserable into hot and miserable and muggy.

    Oh, and they won't work well where it's already high humidity. Southern California/Arizona, they can be really nice, while the temps are still lower. So if you sleep nights they can be pretty effective through most of the year. If you want it to work during the day at 115 degrees, forget it.

    One other nice thing is the ability to turn the water off and just run the air, bringing in cooler outside air so you don't have to open windows and hope for a breeze.
     
    DUNE-T Thanks this.

    it says that it's an evaporator system...meaning you are going to add MORE humidity on top of the humidity outside...

    those are like the evap systems that one can buy for say, his shop. but you need to use them in a dry area, like the southwest....

    anyplace else, and it's counter-intuitive to keeping you cool and humid free.

    from the owners manual:


    Cooling is generated by vaporized cool water delivered by a self-contained electrical motor. During operation it only consumes water and it makes no use of internal combustion engines, nor does it use chemical coolants or emit gases into the atmosphere.

    Sounds like a swamp cooler.

    That's what it is. Won't work in say the Deep South where there is a lot of humidity.

    You mean the Humidity of the east.

    The southwest is just dry and hot. :)

    So, they'll only work on the west and north.

    There used to be small swamp coolers and air conditioners. Hard to find these days. For the cheap and economical.

    Down along the Gulf Coast you could get charged with attempted murder by adding moisture to air with 100% humidity. It could drown you with a cabin rainstorm :)

    Down where there are swamps, those things won't cool a swamp; they create a swamp.

    That's exactly what it is, from what I read. It will be useless in humid conditions, and marginally effective in very hot weather.

    It will also certainly need regular filling with water, and the manual will likely tell you it needs distilled water, or the tubes and whatnot might get clogged by minerals.

    If you operate locally in Arizona, Nevada, or some other places where it is low humidity most of the time, it might be worth installing, but don't expect to use it for all your cooling needs.
