That's a commonly believed "old wives tale"; it's not true.
At least not for the reason given. The tiny "movement" of a dripping faucet makes NO difference.
It is the pressure that breaks pipes when they freeze.....the pressure of the water downstream between the freeze point and the faucet. Thus the dripping faucet prevents the pressure buildup....in THAT pipe.
In an RV, you turn the pump off and open all the faucets; no dripping required.
