The max. input/output temp differential for A/C units is around 15 degrees but that doesn't mean that the max temp differential between inside and out can never be more than 15 degrees. That said, the heat load on an RV on the sun is very high and it is not at all unusual for dual A/C's being unable to keep up in extreme conditions (which virtually defines Texas in the summer ) About all you can do is take some steps as described in the thread, and start up early in the day so you don't get too far behind the curve.
