We purchased a Companion evaporative cooler for our RV from Outback Equipment and wish we hadn’t. The cooler is ok- as long as it isn’t very hot. Kind of defeats the purpose doesn’t it? We need a cooler that cools when the temperature is 30 or more. Even in our compact, well insulated Sprinter van the cooler was unable to knock the temperature down even one degree! That’s not a typo - not even one degree. I sent Outback Equipment an email voicing my complaint more than two weeks ago and haven’t had a response. Not happy. Not with the cooler and not with Outback Equipment. We’d like a refund!
