The fridge is definitely a lot slower cooling down, it often takes mine almost a day to get the fridge down into the 30's. Is the rv pretty level, sometimes the freon doesnt circulate good if off level. A little is no deal but if it is sitting on a slope that isnt helping. If you think there is a problem you can pull the thermistor loose and let it hang. It is attached to the fins and tells the system when it is cool.
