Rule of thumb is ~20 degrees below ambient is about all you can expect from an RV A/C. Might have done better to close all the slides while you were gone. Less surface area exposed and less cubic to cool.

We were talking to someone at an RV dealer (on a completely unrelated matter, but the conversation came around to AC for some reason) just the other day who said not to expect much more than 10-15 degrees below the ambient temp.
Totally wrong. A properly running RV AC unit will cool the outlet air closest to the unit, to 20 degF below the air entering the unit. DO NOT use an infrared temp gun as it will not read air temperature. It only reads radiated heat from a surface.
