Not a mud flap but a debris flap. I put cut down truck flaps in front of the fresh water tank to knock down road debris from hitting the fresh water tank. Stopped at a rest area in South Carolina with our 16TBS and had water flowing out under the truck and camper. Had to replace the fresh water tank due to the impact crack on the front side of the tank.
I will look into mud flaps for the 21 RBS.
