120 amps is more than the normal loads that any RV will have at one time. Your battery capacity is probably 110 to 220 amp hours total, and will get used over at least 4 hours (less than 50 amps per hour) and more likely over 3 days at less than 10 amps per hour average.
Even a 120 amp plug is OK to exceed that amount for short durations, such as running a inverter with microwave for 3-10 minutes. This 150 amp load will not significantly overheat the connector.
