The RV refers will operate the SAME on LP or 120. The BTU's supplied by both LP and 120 are almost identical in cooling capacity.
IF you have a refer that is operating better on LP than 120, you need to verify that the 120 element is indeed pulling the required amperage. What Brand and model do you have? Has anyone changed the 120 element since it was new(they may have installed a lower wattage unit than is required). What is the line voltage? LOW AC voltage will cause lower heat from the heat element. It is also possible the sleeve that the 120 element slides into has slightly separated from the burner flue tube which will cause a loss of cooling on 120. I see you have a Newmar Ventana. IF Newmar installed a Norcold 4 door or a Dometic side by side refer, one of the 2 heating elements may be bad. Doug
