Mud Flaps vs Brush Systems

Hi All,
Well, we just got our new 5'er home and now the mods are underway. First off, the grey/black water drain is slung in front of the axles and I fear prone to flying rocks from the truck, especially on gravel roads. I want to install some sort of mud flap just in front of the whole drain line so rocks/mud don't chip out the plastic line. I am thinking of an L-bracket about 4' long that I can bolt to the bottom of the trailer frame and hang either a tin strip or rubber mat or flap or belting (about 6" wide) from it. Have others adapted your trailer to protect the drain line? What's the best and easiest approach without overthinking this?
Thanks in advance

We mounted duraflaps, work and look great.

I have these on my 2nd truck now, they protect your truck and the trailer also, plus they look a lot better than those receiver mount brushes. Duraflap

I built a full-width mud flap that goes in my receiver, knocks down all the debris my duals throw out the back.

RockTamers, mounting brackets are powder coated, & aluminum. Rubber flaps you can cut to the length you need, & they look a lot better than a brush hanging there.

I went to my GMC dealer and order OEM mud flaps for the front and rear of our 08 3500. Quick easy 30 minute install. They work great at keeping the dirt off the front of the fiver and side of our truck.

I have driven hundreds of miles with both kinds. I consider the brush to be junk not worthy of having on the vehicle. I installed a clear across the back solid flap with 4 inches of ground clearance. It works just great, except when backing in to parking places. Mine was hung on a jointed hanger so it was not too bad even on that. One draw back was: if I ran over a rubber alligator (you are not going to miss all of them). Some will get up under the solid flap and really raise cane before it exits. Never had a serious situation from that however.

Go to a street sweeper dealer and pick up a segment of a strip broom and the channel it fits in. Bolt the channel to the bottom of your bumper and you can slide the strip broom in and out as needed!

Did that on my old Dodge Ram for years. Works well and looks good!

Just our experience on our Alaskan trip....we pulled into Whitehorse Yukon and saw folks removing their stiff across the rear flap from their motorhome. We saw that they each had a layer of 3/4" rocks laying at the base of their windshield on their towed vehicle.

We just had stiff tire flaps behind each of them and no rear flap - stiff or brush. Our towed vehicle did not get any damage for the whole summer trip.

Later when driving the interstate in pouring rain we took note of motorhomes driving the opposite direction. The ones with the stiff flap were throwing an arc of water high toward the windshield. Ones that didn't have a rear flap were tossing water at the tire area of the towed vehicle.

I have Road Wings on my truck and love them. They attach to the rear receiver and do a great job of protecting the front of the trailer. I only wish I had them on the first year as the trailer did get dinged a bit from gravel in a road construction area in Wyoming. I also have a wide mud flap on the rear of the trailer to protect our boat (double tow). They are worth it to me.
