Your method of manually cycling on and off does work most economically, but it can get annoying on a long trip.
In my van (with manual controls) I run the blowers until a comfortable temp is reached, then turn the blowers down to minumum setting. There are temp sensors designed to keep the condensor from freezing up, and by slowing down the air flow, the condensor gets cold faster, and cycles the compressor off more frequently. Most of the time this maintains a comfortable temperature.
