Video Transcript for RoadMaster RoadWing Removable Expandable Mud Flap System Review

Today we're gonna be taking a look at and also showing you how to install the RoadMaster RoadWing Removal Mud Flap System. Available in several different sizes for different vehicle configurations. Where the RoadMaster RoadWing is gonna be a really good solution to help save whatever it is you're hauling, whether you've got an enclosed trailer. In this situation we've got an RV towing a car. On road you're gonna have debris on paved roads. You're gonna have debris to come up, rocks, little pieces of dirt, sand, stuff like that.

But, when you get off road, you're gonna see gravel coming up. You're gonna see dirt. Out in the mountains, trying to get over some of those passes, you're gonna have a lot of stuff that especially dual rear RVs or dual wheel trucks are gonna be kicking up.This is also gonna come in a size that's gonna work for your full sized trucks and SUVs and your mid-size trucks and SUVs. So, regardless of what you're hauling in those situations, you're gonna probably be hauling a trailer, whether it's an enclosed trailer. Maybe you've got a boat or motorcycle behind there.

Maybe you've got a race car on the trailer, and you just don't want stuff being kicked up on it. These are gonna provide a really good solution. Now, all of these are designed to fit around a two inch by two inch shank. So, whether that's gonna be on your ball mount. This is our tow bar for a flat tow setup.

Or, even if you wanna protect items in a cargo carrier. Maybe you don't want stuff bouncing up on that.This is gonna fit right around the shank. You've got two bolts. You've got one here, one located in the same place on the other side. These are gonna take up any of the space.

You can see even when I'm trying to move it, that's real nice and solid. We're not gonna have to worry about his leaning side to side.Now the mats themselves are gonna be 24 inches in total length. We've already trimmed these to work with our RV. You can see we've got them riding pretty good, about an inch over top of the ground. This is what our flap looks like. This is the part that we cut off of the one that we have here. See it's a nice, solid, durable material. It has some flexibility to it. But, it's not like the thin rubber flaps that we see often installed.They've grooved the back. So, you can see this side is smooth. It looks like this. But the back that faces towards our wheels, they've grooved that. Now the grooves run up and down on the back side of our mat. So, they're kind of be sitting like this, and as debris comes and hits them that's gonna help to slow it down and direct it down and under our mat rather than have it just hit it, bounce off, and potentially roll under the mat.On the rest of it, we're gonna have good sturdy, steel construction. It feels nice and thick. Each end is gonna be capped off. You don't have to worry about water or dirt getting in there and causing rust. They've coated that all with a black power coat finish.Now, to get the RoadWing installed, you'll see that we've got the area right here that we're gonna be passing this shank on our item. We're gonna be installing this on our motor helm of the tow bar. This center section, you're gonna see in the expandable version. If you're using either the middle or the smaller size, this is gonna be solid. Your arms are gonna already be attached.As we slide this on, you see our bolts here. We're gonna have those closer to our vehicle. Just put it on loosely for now. We'll get this put back into position and we can resecure it. Now, we're gonna bring our section right up towards the rear of our vehicle. You're gonna have a little bit of a space here. We don't want it to be too far back, because then we'll run the risk of items bouncing over the top. You can see we've got our two bolts here on the bottom. We're gonna tighten those bolts down evenly there.Then, using a 14 millimeter wrench or socket, we can snug those up. You can see, we've installed our mat to our adjustable arm here. We need to slide our arms into each side of the center section. On the non-expandables, you're just gonna attach your mat using those four bolts. Now, once we have those started, we're gonna be able to move these in and out. Basically, these are gonna go anywhere from 102 inches down to 91 inches.I think you're gonna be best suited to have the end even with, maybe just past your bumper just depending on how wide that item is behind you. If you're a narrower kind of item, maybe you don't need all the protection on the outside. So, maybe you bring those in a little bit to give you a little more protection on the inside. Once we get those set where we want them, it's time to come through and we'll tighter up those bolts here in the middle.Now, we're gonna get our RoadWing flaps cut to size. What you're gonna do is measure from the bottom of the bar down to the ground and subtract maybe an inch or an inch and a half. Something to keep in mind, since we're doing an RV with the flat tow setup, we're not gonna really have any sag. So, this rear bumper is gonna stay about where it's at. If you're using any of the other type vehicles or if you're gonna be hauling a trailer behind your RV, you need to allow for the slack.You hook your trailer up, generally the back of your vehicle comes down a little bit. So, you wanna account for the sag plus about an inch. Now, I've marked down the distance from the bottom of the bar to the ground. That mark's right here. Then I just put an inch and a half piece of tape on it to give me that inch and a half. We're gonna cut right along that line. You just need a sharp knife to do it.We'll do just a couple of shallow passes, and eventually we'll have worked through the mat. So, if I just kind of flex that flap back a little bit at the bottom, we'll just keep working through that little bit of flex to help it to expand, make it cut pretty easy. When we get done with this one, we'll go do the other side.That's gonna complete our look at the RoadMaster RoadWing Line of Removable Mud Flaps.

2018 Toyota 4Runner

It fits my needs perfectly



m glad I bought it

2004 Chevrolet Silverado

Great quality and fast delivery





Great product! Saved my F-150 toad from having to get new radiator and headlight after I had to drive over some debris on the highway.


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.


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 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 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.


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.


One mudflap is in 3 pieces out of the b ox.


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.


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.


Very easy to install. Love the fact that there was no drilling into our Rv or car. Highly recommend!


Just want I wanted, I’m very happy.


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.


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.


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.


Great product. Almost covers the back of my moter home. Simple to install. Easy to remove when not towing my car.


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.


Absolutly love this product. Very easy to install. Looks great on my truck. Has done a very good job protecting my fifth wheel from rock damage. Would highly reccommend this product.


Great product!


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.


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.


I like the product .. but the package was partly open when I received it .. I took it out of box and was missing a couple of parts .. I called and talked to Marc and he helped out and parts are being sent.. we feel it was damaged from delivering company.. thanks for the quick action by your staff


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.

  • Roadmaster RoadWing Mud Flap System for a Ford F-150
    The Ford F-150 is a light duty, full size truck. Other trucks that fall into this category are the F-250 and 350 and newer 450s. Larger than that and you get into medium duty trucks. This is not to be confused with a mid-sized truck. A mid-sized truck would be something like a Dodge Dakota. And a compact truck would be a Ford Ranger or Chevy S-10. But your Ford F-150 is a full size truck. So you would use Roadmaster RoadWing mud flaps system # RM-4400. The width is the overall width so...
