Rusty, you must have one of the larger units. Of the three models offered, only the smallest 1800 watt unit appears to be designed to work on 30-Amp 120-Volt power. As you mentioned, the two higher-capacity models need the 240-Volt power only available from properly wired 50-Amp service.
For smaller RVs the lower-capacity model may do OK.
