I had initially purchased a smaller GE unit and although it worked fine it did not cool the room size it had recommended it could cool. So this time we went as big as we could and I'm glad we did. This unit works excellent and has some great additional features the last one did not. We are using it in our toy hauler and could not be happier.  Shipping was sub par to saybthe least but can't blame GE for ontracs short comings. Would recommend and would buy again.
