I have used one of these since 2022 to protect my Grand Cherokee behind my Class A motorhome. Worked fantastic! Sold my Grand Cherokee with the tow bar and tow defender, to a friend, all ready to hook up and go, so I purchased another one. Won't tow without this!

I would have rated it 5 stars had it not been for the problem with one of the extension rod locking latches. After about 8 months I noticed a clucking sound while turning. I determined that one of the extension rods was not locking causing the clunk. I contacted Roadmaster and they explained that the latch needed to be tighten. Once I performed the adjustment it worked as designed, however from the rod expanding and contracting it ripped the nylon Defender Protective Screen and now I have a damaged screen that will cost me $200 to replace.

Quality construction, clear instructions, well packed for shipping and my husband had no trouble with the installation. . . With my help, of course! Can't wait to try the shield in the near future. We have a Hallmark camper that we tow the Jeep behind. Will send photo when everything is hooked up. Congratulations on a quality product.

The Shield does its job and is well built. Used it on a 3000 mile trip last summer and not one rock chip. It took a bit of adjusting to get it to fit properly when I first installed it. Stores fast and ease when leaving the tow bar attached to the RV but very cumbersome and heavy when removing the tow bar from the RV. I can no longer store the tow bar in the RV compartment. I had to store the whole thing in my shed for the winter.

I have about 8000 mile of towing with this unit now. It does it job. No rocks on the hood or in the cowl of the towed vehicle when towing on gravel roads. The front of the vehicle is still vulnerable below the screen but everything above the screen is in great shape. The fabric and the metal parts are holding well. It is still cumbersome to store the tow bar and the Tow Defender off the RV. A quick connect for detaching the Two Defender from the tow bar would be a great upgrade. Storing the Tow Defender on the RV is a quick and ease. If your towed vehicle is new or in good condition you need this protection to keep it in good condition. My old towed had about 25K towed mile and it was trashed in the front. My current towed has never been towed without the Tow defender and I don’t have any chips above the screen level.

Good design, well engineered, fit together well, only issue I had was my exhaust on DP extends out the back, so I needed some more clearance which I got when I added the 2" hitch raise to level the RV to the tow vehicle.
This Lang with the rock guard will save the road.
All products were shipped quickly and the customer service was great.
Also I saved about $100.00 by shopping with etrailer vs other well known suppliers.

One year later...We put around 10K miles on the RV throughout the year in large part in the East Canadian Atlantic provinces and Manitoba. The screen has performed well in keeping those nasty small pebbles from peppering our Jeep which was the reason we purchased this product in the first place. I am glad we made this purchase.

Second year and another 10K miles of use. Its starting to show a little wear but nothing to worry about. Be careful on maximum turn radius turns as the bar may reach either the towing or towed vehicle and bend the fabric bars which are easy to straighten again. Im still glad we made this purchase.

The protector screening is well made. the instructions were not very clear nor were the supporting pictures but the schematic view made it fairly easy to assemble and install with some figuring out. after finishing the install I saw that with the current height setting of the support arms, my RV ladder would rub the left support arm and therefore quickly wear out the fabric, so I took it apart and dropped it down to the bottom holes and its better now.
its a shame there is not an easier way to remove it from the RV than to remove the entire roadmaster hitch from the RV. that is a downside and I may well modify it for that. All in all, this will prevent much of the rock damage in the future and will hopefully prevent me from acquiring so much road tar from pothole repairs. I recommend it and will update this review after I actually use it on the tow car in a few weeks..

This product is easy to install as long as you follow the enclosed instructions. I have not used the Tow Defender today. However, I have friends that have used it with great results. Typically, on a class A motorhome you have mud guards that should protect your tow vehicle but they actually create a bigger problem. I purchased this Tow Defender to compliment the Roadmaster Shield which I currently own. The problem with the shield is that rocks bounce off the shield and hit the rear of the motorhome. The Tow Defender Screen will stop this.

Great customer service. Three days after I order the shield it arrived. A customer representative called me twice to let me know when it was shipped and a follow up to verify it had arrived. Haven't gone on a trip yet, but easily installation. The tow bar I attached the shield to was the Falcon/All Terrain (6000 unit). The shield model number was Roadmaster Tow Defender (4700).

I am glad you have contacted me for my thoughts
I really like the product but find it is too long from the motorhome to the tow vehicle, and we have had to put clips on it to stop it from flopping while towing. I also find the product very heavy to lift, as I have had surgery on my right wrist, and do believe it could be made from lighter structure material.
I also have purchased a road master invisbrake system and can’t say enough good about that product, I really like how it works and would recommend it to anyone, it is well worth the price.
Thanks

Have only used this a handful of times (we don't flat-tow that often), but overall it seems to be a great product. Took my time setting up, checking turns, adjusting, etc. and all went well. Very happy with this. On a 2014 Fleetwood Discovery 40G towing a 2018 GMC Yukon Denali.

Rock protector came quickly, packaged well. One part did not fit as hole was drilled too small. Needed a drill press to correct problem.
Too soon for road test, looks like it will do nicely.

- Which Roadmaster Tow Defender Works With Roadmaster Nighthawk Tow BarHey Herb! The Roadmaster Tow Defender Protective Screen for Towed Vehicles # RM-4750 is what you need for your setup assuming you have a direct connect base plate kit. This is designed to fit tow bars with direct connect base plates which is probably what you have with your Nighthawk # RM-676. If you happen to have a crossbar style with the crossbar assembly # 910021-00 you need # RM-4700 instead. Where are you headed once you get the Maverick set up for towing? Do you have the rest...
view full answer... - Will the Roadmaster Guardian and Tow Defender Work with the Nighthawk Tow BarI do have an option for you but I spoke with my contact at Roadmaster and they informed me that the Roadmaster Stowaway Storage System part # RM-4000-40 which is used to attach the Roadmaster Guardian Rock Guard part # RM-4000 on the back on an RV will not work with the Roadmaster Tow Defender Protective Screening part # RM-4700. In order to use both the Stowaway and the Guardian on your vehicle with a protective screen you will need to use the Roadmaster Tow Defender Protective Screening...

Great question, I get what you’re saying about not wanting threads in the stack-up. Short answer, yes, the Replacement Car-Side Installation Hardware for Roadmaster Tow Defender Screen # RM67ZR does include the correct shoulder-style hardware for this application, even if it may look different from older part numbers like 350099-00, 350101-00, and 350103-00. This is the replacement hardware for the # RM-4750,...

If you already own the 4700 version then you'll need the Base Plate Kit # RM-523198-4 instead. I have confirmed all of this with Roadmaster.

For that you'd want the part # RM-521452-4. This fits the Latitude, Latitude Plus and Limited models. If you have an Overland, Trailhawk, or Trailhawk Elite you'd want the # RM-521451-5. Next you'll need a tow bar which for that the Roadmaster Sterling part # RM-576 is your best option for if you have the Latitude or Limited models since you'll need the included crossbar. If you have an Overland or Trailhawk...
view full answer... - Available Options for Rock Guards to Protect Towed VehicleThere are other options for protecting your towed vehicle other than the Roadmaster Guardian you mentioned. The Roadmaster Tow Defender, part # RM-4700 stretches between the RV and the towed vehicle, deflecting rocks downward before they can damage your vehicle. The Tow defender attaches to the tow bar and the quick disconnects on the vehicle base plates. We also have the Rock Tamers Mud Flap system, part # ERT00108. These flaps install on the tow bar, and are adjustable.

That exhaust tip pointing down is going to go a long ways in dissipating the heat from your diesel engine. The attachment point for the Roadmaster Tow Defender Protective Screen for Tow Bars with Quick Disconnects item # RM-4700 is adjustable so you can move it down the shank of your tow bar to ensure the Heat Shield item # RM62GR is positioned above your exhaust tip. The heat shield is going to cover about 10-1/2" after it's folded and installed. If you...
view full answer... - How to Pick Correct Roadmaster Tow Defender for Flat Tow SetupHey Phillip, so to pick between the two tow defenders comes down to which style of Roadmaster base plate kit you have installed on your towed vehicle. If there's a crossbar between the arms of the tow bar then you need the part # RM-4700. If there is no crossbar then you'd instead want the part # RM-4750.

Along with the Roadmaster base plates you mentioned, the other things you will need are safety chains (if you don't have them), as well as a wiring kit, brake light relay, and supplemental braking system. I'll go ahead and list out the parts for you to make...

How do you like the Acclaim? I attached a picture of this Tow Defender installed on a Blue Ox tow bar for you to check out as well.
view full answer... - What Is Difference Between Roadmaster Tow Defender # RM-4700 And # RM-4750The difference between the # RM-4700 and the # RM-4750 is being able to use them with your base plates. If you have the crossbar on your base plates you will need part # RM-4700. The RM-4750 is not compatible with other style base plates. Since you said you have the Roadmaster Guardian, part # RM-4000, the same issue applies. It is compatible with the base plates that have a crossbar and will not work if you have other style base plates.

This is the easiest to connect and disconnect, and it also makes your tow-bar about 20 lbs lighter, so the # RM-521453-5 is your best...

- Difference Between Roadmaster Tow Defender Protective Screening Part RM-4750 and RM-4700The Roadmaster Tow Defender Protective Screening is an excellent option to help protect your vehicle while in tow from both larger debris and smaller debris. This debris not only dirties up the vehicle but can also lead to damage such as scratches so I highly recommend a protective device such as the above. In regards to the difference between part # RM-4750 and part # RM-4700, the former is for Roadaster Quick-Disconnect Base Plate Kits and the latter is for the Roadmaster Crossbar Style...

- Windshield Protection Recommendations For Flat TowingThe purpose of the Roadmaster Guardian Rock Guard, # RM-4000, is to not only protect the finish and front fascia of your vehicle from rocks and other road debris, but also to keep rocks and gravel from ricocheting off of the vehicle and hitting the windshield or motorhome. To protect the windshield from rocks and debris that may make its way over the Guardian, I recommend checking out the Roadmaster Tow Defender, # RM-4700. The Tow Defender stretches from the receiver to the tow vehicle...
view full answer... - Recommended Rear Skirt to Prevent Road Debris from Hitting Flat Towed VehicleTo prevent road debris from hitting your toad, I recommend the Roadmaster Tow Defender Protective Screening # RM-4700 which connects to your tow bar. If you want the vertical skirt versus the horizontal option, then I recommend the Access Rockstar XL Universal Mud Flaps for Full Size Trucks - 37-7/8" Wide - Smooth Finish # A10000111. This is the closest option we have for motorhomes.

When comparing the Tow Defender and RoadWing, the Tow Defender will offer more protection but it will also be a bit more work...
view full answer... - Can Roadmaster Tow Defender be Used with Blue Ox Tow Bar I do have a solution for you, however the Roadmaster Tow Defender # RM-4700 referenced in your question is only compatible with Roadmaster tow bars with Quick-Disconnect systems. If you are using a Blue Ox tow bar, along with Blue Ox brackets, you will instead want to use the Roadmaster Tow Defender # RM-4750. This product's heavy-duty nylon screen will do a great job of deflecting rocks and other road debris down and away from your towed vehicle. It will fit any RV with a 2 inch hitch...

For that reason, you'll want to instead use the Roadmaster Tow Defender # RM-4750 model. This Tow Defender is designed to use with Blue Ox base plates and the Roadmaster NightHawk # RM-677 tow bar that you're already using.

This is definitely part that is often overlooked. Until the front of the towed vehicle gets all chipped up, that is. What's the next trip you have planned, Gerald?
