The 20 degree temperature difference isn't a hoax perpetrated by Coleman. A 15-22 degree drop across the coils is a commonly accepted standard throughout the entire HVAC industry. The outside ambient temperature isn't what's important.
What's important is the temperature of the air that the unit sucks in and the temperature that the unit blows out. Since these units are recirculating the air within the trailer, the intake temperature would be the ambient temperature inside of the trailer. In the OP's case the intake temperature was 85 degrees and the unit produced 65 degree air, so it's working correctly. If a unit is undersized for the space or not plumbed correctly then the unit will not be able to keep up. It won't be able to produce enough conditioned air to lower the temps in the current conditions.
