Well the Artic Air Tower was pretty useless.....the 12 volt fan I bought is really nice though.
Amazon.com: Quick Products QP-TE1-0126 Boundless Breeze Ultimate RV/Marine Fan - 12 Volt: Automotive Luckily on the Maine trip night time temps during boondockin were cool. It did get to 94 in Maine but we were connected so the AC worked great.

I bought an Artic Air Tower today at Home Depot. It uses 54 watts on max and says it does 100 sq ft. I will say when it was really hot today it couldn't do much 92 degrees going in 86 coming out. At the end of the day it was working pretty decent 81 degrees going in 74 coming out. It is an oscillating tower fan so it will work as a fan. I am going to try it on the trip and we will see how it goes....I think it will work to keep the temp down while sleeping.

We don't plan to use the camper during the summer.....too hot and too many people. We will use it during fall and spring mostly. The personal cooler was definitely working but only if you are directly in front of it....didn't mean to imply it was cooling the camper. The Hessaire may work for us during the months we would use it......I am a little concerned with the physical size of it and it may be overkill for the trailer size as it is designed for 500 sq ft.

Don't be fooled. We're not in the high humidity part of the year yet.
Check the wet bulb temperature not the dry bulb temperature. A swamp cooler can reduce the temperature to a number around 10 degrees above the the wet bulb temp. It can't cool below that because at that point your air will be at 100% humidity in the trailer and you'd have to condense water out to get it cooler, only an a/c can do that. 100 % humidity will be very uncomfortable when the temp gets up to the high 60s/low 70's. So if you only want to cool in the spring when the humidity is still low ok but in the summer in the East not so much. comfort zone |

I checked my Artic Cool individual cooler which is a mini swamp cooler. It is about 95 degrees in camper and when I checked the air coming out of cooler it was about 64 degrees. I think these may help if you blow it directly at you. They run off usb plug so they don't draw much. I got 12" 12 volt fan that looks to be similar to the overhead fan in the bathroom so it puts out plenty of air. Still a little curious about the swamp cooler as I was surprised at how cool the air from the mini swamp cooler was....I may take another look at the Hessaire

Not last long is right, maybe 40 lbs of ice to give 9000 btu of cooling, roughly an hours worth. And the air coming off it would be very damp.
I agree with you, hotel if it's really hot, not worth being miserable. But the fans blowing on you will keep you feeling comfortable for about another 10 degrees or so, we use them a lot in the summer. |

We would only be using it for our overnight rest stays so max use would be about 8 hours we have electric hookup for the rest of the stay. This is all East coast travel so humidity would probably be high enough so it wouldn't work. Some of these units come with freeze containers I guess to add to the cool but I'm sure that wouldn't last long. I'm hoping that we are far enough north that the overnight temps will still be pretty cool......otherwise it will be the motel option.

If it was dry enough to work (which it won't be where we live) it would use roughly a gallon of water an hour to cool the trailer equivalent to a 9000 btu/hr a/c. You could go through your whole fresh water tank in a day.
You should be fine in Maine in June. You can get a couple of 12v fans to direct where you are sitting or sleeping. That's what I do. You need a 12v power port, a 12v wye, and extension cable or two. Here's what I use: fan If you get unlucky and run into really hot weather find a campground with ac hookups and run the jet turbine mounted on your roof. |

Sorry yes it was watts. Our boondocking is more staying at Harvest hosts or Walmart so we can probably find water okay but if it doesn't work it may not be worth the effort.
