The flap itself is excellent, having a receiver mounted one very convenient. The issue I had was the single bolt used to snug up the entire setup. The previous units had two one one each side. To Roadmaster’s credit they were willing to accept my hitch mount and replaced with a two bolt version which solved the issue completely.

We bought these mud flats to protect our small Fiat 500 which we tow behind a small 30 ft class A motorcoach. The Fiat rides low to the ground. Before installing the mud flaps the Fiat sustained damage to a front parking light when hit by some small animal road kill. It also picked up tar in a construction zone. We had to cut the bottom of the flaps to shorten them but was otherwise an easy installation. They do drag a little when we enter/exit a steep incline. They do the job. We have put on about 3000 miles since we installed them without damage to the car.

Okay there are only a couple small things that I have to grump about. First is that the mud flaps come rolled up and it is very hard to get them to lay flat now as you can see in the picture. Second there is no center flap included for total protection from debris flying from under the vehicle. Last thing is there should be a bar included for the bottom of the flaps to keep them laying flat all the time. On the other hand...Etrailer.com really rocks!!! This is the first time that I have every used them and I will be using them again for sure. You are always being updated on the progress of your order. You order ships out right away and I had my order in a couple days. The price of this product from Etrailer.com was the best on the net that I could find. Oh yeah, and the fact that I got this item with free shipping is a total plus to me. Again I would recommend this site to anyone because they are good.

This is a high quality product that installs very easy. Unfortunately, when I stood back and looked at it, I realized that it won't work well for my application. The rear wheels of my dually will still send debris and mud over the top of the mud flaps outside the rear bumper of the truck. I also find that because they extend beyond the width of the dually, they will interfere with the front of my 5th wheel when making a sharp turn or backing. I will have to add some additional mudflaps immediately behind, and outside of the dually tires in order to prevent the debris from being thrown over the mud flaps. The Road Master mud flaps would be the perfect solution behind a motorhome, but not that great for my truck and 5th wheel.

The mud flaps seem well made and are solid once mounted to my RV. Installation was easy, but there are quite a few nuts to tighten, so I would recommend a power drill if you have one to make it faster. The most time consuming piece of the installation was trimming the flaps. I followed the advice shown in the installation video on the eTrailer site and it was relatively easy, although it did take around 10 minutes for each side to trim the length to fit. Overall, these seem to be a well made product with an easy installation. I can not comment on durability yet, since I have just installed them, but the rubber flaps seems very sturdy, and I would expect them to last a long time.

I bought and installed these mud flaps on my 2014 Forest River Georgetown XL motor home to help protect my 2015 Chevrolet Equinox that I tow. they have performed flawlessly for me from California to Florida and return. I highly recommend this product.

Very easy to install and looks great. I shimmed my receiver hitch to ensure it did not wobbel. Protects my fifth wheel from gravel and road debris.

Review from a similar RoadWing in Mud Flaps


The product did what I wanted it to do. It kept stones and debris from hitting the camper. However, when you cut the flap to a height that is compatible to a good running height ( 4" above the road) the flap drags going in and out of parking lots. On one trip it drug so often the flap had a tear at the mounting bracket. I sent an email asking if I could purchase just the flap but I got no response. So I improvised and put another metal bracket joining both sections of the flap.

Review from a similar RoadWing in Mud Flaps


First off, etrailer carries a lot of great products and the customer support is outstanding. The RM4400’s showed up quick and in great shape. I like the one piece frame design, which made for a quick install. The product seems to be very solid. These were purchased to be used when pulling my new boat. I keep the assembly stored out of the way and attached to hitch drop, then when I’m ready to hitch up the boat, these are on and ready to go in thirty seconds. The true test will be in a couple of weeks on a run to Alabama for the spring Crappie hunt. Thanks etrailer.

Review from a similar RoadWing in Mud Flaps


This RoadMaster RoadWing Removable Mud Flap (RM-400) is fantastic. The Mud and rocks that I used to get on my trailer are almost non existent now. I only wish I would have purchased it before the first trip with my trailer. I only took one trip to realize the extra mud flaps I put on My Ram 2500 were not enough protection against road debris. Great investment and product. Highly recommended.

Review from a similar RoadWing in Mud Flaps


The rubber mud flaps were packaged rolled up with the metal bar mounting bracket inside the rolled up mud flaps. The loosely packaged assembly allowed sliding around of the rolled up mud flaps along the metal bar mounting bracket which put black scuff marks on the "Roadwing" insignias.

Sure, works good and attached easy, just hock up fifth wheel or pull type to see suspension height which will be lower, Mark with a sharpy and cut with circular saw, keep flap few inches off road surface , don't let in drag, saves a lot of cleaning trailer fronts.

  • How to Use Roadmaster RoadWing on 2015 Chevy Silverado 3500 with 3 Inch Receiver
    As long as the ball mount that you're using is a 2" then you can use the Roadmaster RoadWing Removable, Expandable Mud Flap System for RVs, Buses and Dual-Tire Trucks # RM-4400-102 without any issues. These mudflaps do not connect directly to the receiver so you should be able to make this work on your 2015 Chevy Silverado 3500. If you don't have a 3" to 2" reducer sleeve you can use the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408. If you need a ball mount for a...

  • Recommended Mud Flaps for a 2016 Chevy Silverado 2500HD Towing Airstream Trailer
    According to Roadmaster the RoadWing Removable, Expandable Mud Flap System # RM-4400-102 requires at least 2" of space on the ball mount shank. Since this is the case and you have less than enough space I recommend installing custom mud flaps that install on your fender. The WeatherTech Mud Flaps # WT120035 are actually an excellent choice for your 2016 Chevy Silverado 2500HD because they install easily plus they stick outside the fender a bit as you can see in the attached installation...

    You can use the RoadMaster RoadWing # RM-4400-102 with your TorkLift SuperHitch # TLD1100 on your 2002 Dodge Ram Pickup, but I am not sure if you will be able to utilize both receivers with the mudflaps installed. If you are only using one of the ball mounts then this is a great option for you as the mudflaps are 36" wide.

  • Compatibility of the Roadmaster RoadWing Mud Flap on a 2014 32 Ft. Grayhawk RV
    If you have a 2 x 2 inch hitch installed on the back of your 2014 Grayhawk RV, then the Roadmaster RoadWing Mud Flaps, # RM-4400-102, will fit. The flaps measure 24 inches long x 36 inches wide. By measuring from the ground to the bottom of your hitch opening can give the clearance you will need to make sure the mud flaps will not drag on the ground. If the measurement is larger than 24 inches, then the flaps will not drag.

  • Preventing Rock Chips and Road Debris Damage when Flat Towing a Vehicle Behind an RV
    Hopkins Heavy-Duty ArcticGuard Snow and Ice Windshield Cover # HM17529 would provide some protection against rocks but it is not meant to be used while the vehicle is moving despite the fact that the RV would be blocking most of the wind. It would ultimately result in damage and/or loss of cover. I recommend taking a look at our selection of vehicle guards and related parts, see link. Or you might also consider some hitch mounted mud flaps such as # RM-4400-102.
