Radiator shops love them because they reflect rocks forward which can damage rear radiator and paint. Leave it on but covered with a highly damped material.

I was in denial since I towed my CRV 60,000 miles with no protection and no scratches. Welcome to the Alaskan Highway and paint damage, radiator dings and new windshield after spending $140 on 3 chips. I'll have a Protect A Tow fabric shield next summer which is the best device.
On our trip this summer, we used no rock protection. The damage was simply one chip and one crack due to an overzealous pickup truck driven by a teen-ager who thought it would be cute to do about 60 on the dirt road between Beaver Creek and the Alaska line coming as close to our RV as he could, thus throwing up stones. Other than that, the real battle damage on our 30 footer happened 5 miles east of Bismarck, ND in a construction zone. There the steps were damaged and we lost the compartment covers on the right side of the rig.
