I know that the answer depends on the current draw of the RV, but am wondering if it would be safe to run the AC on a 100 ft 30 amp cable. The answer is probable to turn on the AC and measure the voltage drop at a plug, but buying a 75 foot cord just to find out could be an expensive experiment.
I think 30 amp RV chord uses 10 awg wire. At 100', you should have about 5 percent drop. So if you have 120+ at the pedestal, you should be fine, with nice clean connections between chords, and at post.
