This heavy-duty nylon screen blocks gravel and road debris from damaging your car as you're flat towing. Mounts onto your tow bar and RV hitch receiver with included brackets. Rolls up tight for storage on your RV's hitch.


Product arrived quickly. It was well constructed. Watched the etrailer video and read through the instructions and started to install. The 2 3/8 by 1" bolts and nuts were missing otherwise I would have given it a 5 rating. Luckily I only live 1 mile from the hardware store so I went ahead and got 4 because they were only 35 cents each. Rest of installation went great and test drive was good looks like it should do the job. Ready for the trip and will follow up on performance.

Works Perfect. One 1200 mile round trip from SC to Florida and Two 2000 mile round trips to Michigan. No noticeable chips on the Wrangler. Easy to roll up and unroll for use.


Just installed. Installation video was much better than the Roadmaster directions. Seems like it should greatly reduce debris on the front of my towed vehicle. Had to drill new holes in the rear arm per the instructions due to the wider spacing on my F150 tow brackets.



Doing great a year later. This deflector really has helped keep the road grime off the front of my F150 I tow. Definitely a must have to protect your tow.


A little modifications were required to fit it in between the RV and the Jeep. The Winnebago Forza receiver hitch was recessed in close to the back cap, so I had to extend the tow bar out and use the pin hole near the end. Moved the flexible arms to the inside pockets of the defender. That tightened the fabric up just enough. Will have to fold the original pocket around and stitch it up to the underside to keep it off the rear cap, and exhaust pipe elbow.


I love this product. We installed it on our Roadmaster Nighthawk towbar. The very first trip we took proved it's value. We towed our 2023 Equinox LT (AWD) through a section of road construction where they had just laid down aggregate and spray tar. I was really nervous that our white car was going to be covered in flecks of tar. But the Tow Defender did it's job... the car was almost spotless! Great job Roadmaster and etrailer!


We have so pleased with the screen. It has saved our car on numerous occasions. It takes a licking, but has held up well. We highly recommend it!



The product works as advertised. It is mostly simple to attach, although if the car isn’t square to the van it can be a little tricky to connect. There hasn’t been rock dings after a year and a half. The fabric shoes no signs of rips or tears.

@Eileen We're glad to hear your # RM-4750 Tow Defender is working well for you!


Easy to install. Had to drill two holes to fit baseplate. Protected our toad very well.


Fit perfectly.


The product works well and is constructed well. I gave it 4 stars because it mentions about being to close to the exhaust and causing damage to the fabric but doesn't talk about other possible concerns. I have a Tiffin 2018 Allegro Red motorhome. My ladder on the back of my motorhome interfered with proper operation of this part. My solution ending up being to cut off the lower section of my ladder. I have attached pictures so hopefully someone can see this as an issue before purchasing.


I received my order quickly after Amy got it entered. I look forward to installing it. Amy provides excellent customer service!


Working as desired totally pleased


Over the past few years, I've ordered several items from etrailer. The purchasing process was very easy and timely. They're instructions and videos for installation are spot on! I will continue to buy from etrailer for my motorhome and towing needs,. I needed to customize the screen, simple drilled two new holes for my blue ox brakets.


We have towed our 2017 Jeep Grand Cherokee over 15K miles behind our Class A motorhome in the past year. I'm happy to say that the tow defender did it's job well. Can't find a single rock chip on the jeep.

Im still very happy with the Tow Defender. Still no rock chips on my toad or the rear of our Class A. I am super pleased with this product.


Works as advertised. Etrailer customer service is excellent.


I purchased the Defender to protect our new Equinox during our trip to Alaska. I wasn't sure how it would hold up to all the gravel roads and construction typical of Alaska roads. I was extremely satisfied with its performance and ease of how quickly it attaches to the toad. We now use it everytime we tow.
I did have to modify the ladder on the motorhome because the lower loop rung hung below the level plane of the defender. It was an easy modification and worth the tradeoff for the Tow Defender.

Good as new! The durability is exceptional. We never tow without it.


etrailer is great! Prompt, knowledgeable, courteous service. I received my order ahead of the projected delivery date. Jessica in Customer Service was especially helpful. I will definitely do business with etrailer again!


Easy to install and works great


The fabric is too short for my application. I had rig up some bungee cords to make it fit. My tow vehicle is a Dodge Ram truck. It fits now, but took a lot of effort to make it fit.


I have not used it yet. That’s why I’m only giving it a 3 star review. After I’ve used it a couple of times I will see just how well it protects the front of my jeep. At that time I will give it a new rating. When I do use it I’m hoping it perform as advertised.


Installed it on our 2019 Chevy Equinox on the back of our 2004 Itasca Meridian and everything fit as it should, easy to assemble, I will need to install an 8 inch extension to my receiver hitch to provide clearance for the exhaust pipe, looks good confident it will keep debris off of our new car. Thank you for the great service and great products.



In the year since I purchased the defender we have traveled over 13000 miles from snow in the north to sand in the south west heavy rain in the mid west and our 2019 Chevy equinox shows no signs of damage. I do have some slight damage to the edge of the defender from the exhaust of the motor home but it doesnt cause any problem, it still rolls up when not in use. Very good product, I would not tow without it.


Easy to install and works great


Product works well


After a long trip to Alaska we stopped using it as it was starting to fall apart. Wouldn't get another one.


Light weight steel frame starting to rust. Screen is in great shape after 8,000 miles

Its sad to hear that this has become a problem for you. This is something that is common rust will begin to form due to exposure or road debris. When this happens we recommend touching up the rust with some rust-oleum type of paint. I have a link below for your reference:


Had to drill new holes to get it to line up to the towed mounting bracket otherwise install was easy. Once you get your method down on/off is a breeze. It must be working, no stone chips on the Jeep since I started using it and the bottom always has road grime on it. Would be nice if the straps for rolling it up when not in use were attached somehow (one less thing I have to keep track of). it would also be nice if there was some kind of loop sewed in mid point to clip the electric and air brake lines to.


For me, this is a must to ensure debris does not kick up on the towed vehicle.
