Proper placement of full width mudflap

I'm getting that too - in fact it trashes the toad. How in the world does the flap do that? Is it just air current or does it flip it up off the street?

I even went so far as buying a new purty one then never mounted it. Saw the same thing on our trip to Alaska. Just a good pair behind the drivers and if wanted a small pair for the steers, but I did hear some complain the steer one picked up dirty water in the rain or on wet pavement but I did't notice any.

It can also throw rocks onto your towed vehicle. We only had flaps behind each tire, not the whole rear one.

On our Alaska trip we saw folks taking the big flap off. We drove the same road they did earlier in the day. They came in and showed us the layer of 1/2" rocks laying at the base of their windshield.

On our whole trip we had absolutely no damage.
