Even with the 2 units, if I wait until it is already getting hot out to try and cool it down, it can take a while but, it is significantly faster than a single unit alone but, we have seen days well over 100 here since we got the camper. It will cool down to 65 if you want once the sun goes down with no problem. The bedroom will get as cold as you can handle any time of the day if you close it off and are not trying to help the rest of the trailer. We use fans to circulate the air.
