is this your first RV? if so, RV fridges/freezers work different than the ones in your house.
the fridge/freezer are cooled by absorption refrigeration, not by a compressor like your home fridge.
it has to remove heat inside to cool the compartment. because the freezer compartment is smaller, it gets cooler faster.
it usually takes 8-10 hours for the fridge to get cold. that's why many of us start cooling it the night before we leave for the campground.
a few hours isn't enough. just be patient and it should be cold by morning.
