I turn our 4 door Norcold refrigerator on at least 24 hours before we put stuff in it. That's normal.
Every RV we've owned took about 24 hours for the refrigerator to cool down and stabilize.
Things will speed up as time goes on. The night before we leave a campground I drain my tanks and put the sewer stuff away. Then I don't have to mess with it in the morning.
We never leave our awning deployed over night. Have had two blown off so we don't use it unless we need it for shade while we are in the campground.
