Full width mud flap in receiver.

I got a set of rock tamers off Craigslist, fastens to bumper hitch. I see a significant decrease in debris on FW.

Thanks in advance for your input.

Good question...I know with A's, a minimalists approach is best using just the OEMs mud flaps behind the duals. Curious what people say about 5th wheels...so, this is a placeholder post.
