Which component is least likely to be found in an RV Systems Monitor Panel?

The engine oil pressure gauge is least likely to be found in an RV systems monitor panel because this type of panel typically focuses on the monitoring of various essential systems within the living space of the RV, rather than the mechanical aspects of the engine itself.

RV systems monitor panels usually indicate levels for water tanks, both gray and black, as well as battery levels, to help the user keep track of water waste and the power system. These components are crucial for the operation and convenience of the RV's living quarters. Engine-related gauges, like oil pressure, are generally found in the vehicle's dashboard or engine monitoring systems rather than on the systems monitor panel specific to the RV amenities. Thus, the presence of an engine oil pressure gauge does not align with the typical functions of an RV systems monitor panel.
