I probably should (and eventually will) get the gravel guard, but in the meantime I'm using
Road Wrap for the tow car and will probably put on the Precept this summer.
Tried it on our April trip and while a bit of hassle to put on the first time, it did keep the nose of the car and side mirrors very clean underneath. Manufacturer says it will help again potential gravel & rock chips, but we'll see this summer.
