evap cooler? July 09, 2009, 10:43:53 am Yahoo Message Number: 103773I'm aware of the roof mounted evaporative coolers. Just wondering if anyone has tried one of these? http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200332791_200332791for $139 (on sale) from Northern tool, seems like less of a hassle to stick this under the dinette table on the MB than to install that roof mounted turbo-cool. BUT . . . the few reviews I could find on-line have been spotty. Note this unit is 115 VAC, which in my case isn't an issue as I have a whole house inverter.Thoughts??bumper[Non-text portions of this message have been removed]

Thus, I guess you would be using it for boondocking, where the roof AC would require the generator. My guess is that it is much less energy-efficient a design than the rooftops designed for 12V, so you may find it unsatisfactory for extended stays. Also, it will allow humidity to build up inside more than the rooftop units, unless you are ALSO powering a roof ventilator fan. My experience with our rooftop unit is that it works fine as long as it is running, but you quickly feel hot and sticky once it is off, due to the raised humidity. Of course, it only works well when it is extremely dry, and the temperature differential will eventually creep to only 20F max. For us, it works best keeping the interior comfy during a desert rest-stop, or any other brief task.Steve

Most all our camping is boondocking in the dry high desert. I realize that you have to keep introducing dry outside air to get any cooling from an evap unit. And you bring up a good point. One would have to provide additional outside venting to do this and the humidity would likely still build up in the LD, so cooling performance would drop off as this occurred. Problem with the MB, is there's no good spot on the roof for the TurboCool except for the rear hatch over the couches. I'd have to move the Fantastic fan from there and probably install it where the hallway vent lives now.bumper

I bought it to also put under a table and move some air. It does not cool a large volume of air, but tucked under the table, and directed at your legs it may be sufficient. But really it is not much better than a humidifier unless you fill with ice, then when melted refills the water tray. The cooling media is a screen on a roll that rotates into the water tray to keep wet. It does not have a pump. If I had it to do again, I would opt for the pump, mesh pad, and flow thru fan.Terry
