The "Regular" extension cord is your problem. If you have a heavy one, and the run is not very far, the most you will get out of it is 20 amps, most likely only 15 amps. The heater alone will draw 12.5 amps, the smaller extension cord and the length of the run will cause a voltage drop under load and send the amp draw through the roof. Your best bet is invest in a proper extension cord and have a proper RV outlet installed.
