Should voltage drop be a concern, since there is approximately 40-50 feet of cable (travel trailer wiring + extension cord) between the outlet and the AC?
Voltage drop is always a concern, especially since you've forgotten to include loss in the run from the house breaker box to the receptacle from which you're drawing power. The key is unloaded source voltage - if it's a nominal 120 vac at the receptacle as it should be you can easily sustain considerable loss and still see well in excess of 110 vac feeding the A/C with the compressor running. Nothing in your post suggests you've even bothered to check so that would be your first step ... if it is I'd have no issues running the A/C on this circuit.
