Do you need a license plate on a homemade camper ? - license plate for homemade utility trailer in ontario

We have two home-made camper drop, I wonder if the states continue (TN and NC), in particular, require a license or an identification mark to make the trip? They are only about 5x9 meters tall, the size of a utility trailer?
