Rear Rock Guards...An Interesting Observance Today

Haven't had rocks and such on ours yet. But I do notice dirt settles on the toad. Just a thought. Maybe the flap creates a Venturi effect. Creating a low pressure or vacume on the back side of the flap picking up dirt and rocks.

Now I honestly believe the flap will save my but someday from running over something. Raising the flap might help if its close to the ground. Also perhaps drilling some larger holes or slots would help break the vacume effect.

Just a thought.
