1. A monitoring system for detecting a vehicle hazardous condition of a recreational vehicle, the monitoring system comprising:
a processor; and
memory comprising instructions that when executed by the processor cause the processor to:
obtain vehicle occupant sensor data associated with one or more occupants of the recreational vehicle;
detect whether the recreational vehicle is in a vehicle hazardous condition based at least part on:
historical lateral acceleration data, from a first period of time, that indicates preceding lateral movement of the recreational vehicle,
orientation data, from a second period of time starting after a start of the first period of time, of the recreational vehicle, and
the occupant sensor data; and
activate, in response to a detection of the vehicle hazardous condition, a distress mode of the recreational vehicle to trigger an emergency response.
