Video Transcript for Roadmaster Guardian Rock Guard Review

Speaker 1: Today we're going to be taking a look at the Roadmaster Guardian Rock Guard, part number RM-4000. When we go to flat tow a vehicle, we have a lot of issues with road debris flying up and hitting the front of our vehicle. Whether it be rocks or gravel or anything else, we don't want the paint to be scratched, let alone a headlight broken. Our Guardian's going to protect the front of our vehicle and make sure the paint stays in nice condition, as well as the headlights. Our Guardian's going to be made out of a molded polyethylene material with a hollow core, so it's going to be extremely durable but also very lightweight.Now our Guardian is going to be compatible with all Roadmaster base plates that have the quick disconnect style crossbar, which is sold separately. This center section of our Guardian is going to be attached directly to the base plate on a bracket, and the two side panels are going to have a connecting rod that's going to connect those to the center.

Now, because of its design, we're going to be able to remove in a manner of seconds and actually fold the sides in for a smaller footprint so we can store it.One of the nice things about our Guardian is that it does remove extremely easily and is easy to store. We can simply just pull those pins out, loosen up those thumb screws and we can pull the whole assembly off and set it aside. And that will finish up your look at the Roadmaster Guardian Rock Guard, part number RM-4000.

I won't have a chance to actually use this for a couple of weeks, but I have no reason to doubt I will be highly pleased with it as others have been. For now, I just want everyone to know what a FANTASTIC place etrailer is to do business with. My Guardian arrived much sooner than I expected. This is a company that really delivers. Best company I have ever dealt with. I will update my review later. If you are going to get this, I highly recommend the Stowawy which allows you to easily store the Guardian on the hitch receiver on your motorhome. 109952

a good solid product by Roadmaster that looks to protect the front end of my Jeep Grand Cherokee . the install went well with only one small problem, the Stowmaster tow bar pop-ups interfere with the RM-4000 when in the store position. Other than that it is a well built product. 182194

Do you have a question about this Accessories and Part?


  • Difference Between Roadmaster EZ4 and EZ5 Base Plates for 2017 Jeep Wrangler Unlimited
  • Both the Roadmaster EZ4 Base Plate Kit # RM-521448-4 and EZ5 Base Plate Kit # RM-521448-5 will fit on your 2017 Jeep Wrangler Unlimited. The primary difference between the two designs is the way they attach to the tow bar. The EZ5 does not use the quick-connect crossbar which provides a cleaner look, but prevents you from using some accessories that mount to the crossbar such as a Rock Guard like the Roadmaster # RM-4000. If you are at all interested in using a rock guard or protective...

  • What Is Difference Between Roadmaster Tow Defender # RM-4700 And # RM-4750
  • The 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.

  • Parts Needed to Flat Tow 2019 Jeep Cherokee Limited, Latitude or Latitude Plus
  • For your 2019 Jeep Cherokee you'll need to first start with a base plate kit. 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...

  • Recommended Rock Guard for Use with Blue Ox Tow Bar
  • The Roadmaster Guardian Rock Guard # RM-4000 is designed to mount on any Roadmaster tow bar that has quick-disconnects. Since this item has not been tested with a Blue Ox tow bar I cannot guarantee compatibility. It might work but modifying it will void your warranty. I recommend using a Blue Ox product like their KarGard Towed Vehicle Protector # BX8870. This will work with most Roadmaster and Blue Ox tow bars, excluding the Roadmaster StowMaster or Blue Ox Acclaim tow bars. It is also...

  • Will the Roadmaster Guardian and Tow Defender Work with the Nighthawk Tow Bar
  • I 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.

  • Comparing The Roadmaster EZ4 And Roadmaster EZ5 Base Plates For 2017 Ford Edge
  • Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-524454-4 is a very similar system to the EZ5 Base Plate Kit - Removable Arms # RM-524444-5 which are both a confirmed fit for 2015-2017 Ford Edge SE and SEL models. The difference is the EZ5 has the streamlined design that removes the need for the quick-disconnect crossbar. This baseplate will not work with the Sterling Cables, so the cables need to be attached to the frame of the vehicle. The EZ5 although much cleaner and more...

  • Protective Screen for 2018 Jeep Wrangler JL with EZ5 Base Plates
  • There is a solution for you to protect your 2018 Jeep Wrangler JL, but the Roadmaster Guardian Rock Guard # RM-4000 is not compatible with the Roadmaster EZ5 Base Plates # RM-521450-5 you have installed. Instead, I recommend the Roadmaster Tow Defender Protective Screening # RM-4750 which will do a great job of protecting your Wrangler from debris. It works with Roadmaster motorhome-mounted tow bars, which is exactly what the EZ5 base plate kit is compatible with. I have added links...

  • Parts Needed for Flat Towing a 2014 Chevy Equinox with a All Terrain Tow Bar
  • To flat tow your 2014 Chevy Equinox you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, possibly a high-low adapter, and a few additional accessories. The base plate kit that works with both the Falcon All Terrain # RM-522 you referenced and your Guardian Rock Guard # RM-4000 is the Roadmaster EZ4 Base Plate Kit # RM-523160-4. For safety cables I recommend part # RM-643 which are coiled to keep them from touching the ground and...

  • How to Protect Flat Towed Vehicle's Windshield/Paint

Instead you'd need something like the Roadmaster Guardian Rock Guard part # RM-4000 which is designed to attach to a Roadmaster flat towing setup. If you could get back to me with the brand of flat towing setup you have I can check to see what the best solution would be for you. For example, if you have...

  • What is Difference Between EZ5 and EZ4 Roadmaster Base Plate Kits for 2019 Jeep Wrangler
  • For your 2019 Jeep Wrangler the EZ5 kit part # RM-521450-5 is a fit and what makes it unique to the EZ4 part # RM-521450-4 is that the EZ5 does not require you to use the crossbar that comes with Roadmaster tow bars like the Falcon 2 part # RM-520. The kit attaches directly to the tow bar whereas with the EZ4 you have to use the crossbar. Not having to use the crossbar makes connecting and disconnecting a bit more easy, but the trade-off is that you can't use a Rock Guard like the #...

  • Roadmaster Guardian Rock Guard Recommendation for a Roadmaster Flat Towing Setup

This product is compatible with your setup, would work great, and is easy to use. Check out the install instructions I attached for more info on how it installs and works.

  • Rock Shield that Will Fit Roadmaster and Blue Ox Tow Bars

  • Rock Guard for Blue Ox Tow Bar and American Coach Tradition Motorcoach
  • I recommend going with a Blue Ox KarGard, # BX8870, because you will not have to adapt anything and it is priced a little lower than the Roadmaster guard. The Roadmaster Guardian, # RM-4000, is designed to fit Roadmaster base plates and tow bars and has not been tested for fit on Blue Ox products.

  • Fit & Comparison for RM-4700 & RM-4750 on a 2015 Jeep Wrangler Unlimited Sahara w/EZ4 and Falcon 2
  • I can help you figure out which parts you will need to protect your vehicle from rocks when flat towing. The main difference between the # RM-4700 and the # RM-4750 are where the screen mounts to the tow bar and their compatibility with certain brands of tow bars and base plate kits. For your 2015 Jeep Wrangler Unlimited Sahara, I recommend the # RM-4000 Roadmaster Guardian Rock Guard and the # RM-4700 protective screen, because it has better coverage.

  • Difference Between Roadmaster EZ4 and EZ5 Base Plates for 2014 Honda CR-V
  • As you mentioned in your question, both the Roadmaster EZ4 # RM-521567-4 and EZ5 # RM-521567-5 Base Plate Kits are confirmed to fit your 2014 Honda CR-V. The primary difference between the two models is that the EZ5 does not use a quick-connect crossbar to attach to the tow bar. This will in turn provide a cleaner, less obtrusive look. The drawback, however, and why I tend to recommend the EZ4 model, is that the design will not accommodate many accessories that mount to the crossbar...

  • Guardian Rock Guard Compatibility with Roadmaster Base Plates on 2019 Jeep Cherokee Trailhawk
  • For your 2019 Jeep Cherokee Trailhawk, the Roadmaster EZ5 Base Plate Kit - Removable Arms # RM-521451-5 is not compatible with the Guardian Rock Guard # RM-4000, but it is compatible with your Falcon 2 tow bar # RM-520. The better option for you to enable use of both the tow bar and your Rock Guardian # RM-4000 is to use the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-521451-4. I confirmed with the manufacturer this is the correct fit for your 2019 Trailhawk.

  • What are the Dimensions of the Roadmaster Guardian Rock Guard # RM-4000
  • The middle section of the Guardian Rock Guard is 37-1/2 inches wide and 26-7/8 inches tall. The two side panels are smaller at the top than they are on the bottom. The top, in width, is 15-1/2 inches but at the bottom is 18-1/8 inches. They are both 26-7/8 inches high as well. When open, the guard will measure 68-1/2 inches wide at the top, 73-3/4 inches wide at the bottom, and will be 26-7/8 inches tall. When the guard is folded up it is 37-1/2 inches wide and still stays 26-1/2 inches...

  • Thank you for your 2015 purchase of Blue Ox base plate kit # BX2628 for the Ford Edge. I did not find history for a Blue Ox tow bar so I do not know which you have. The Roadmaster Guardian Rock Guard # RM-4000 fits only on their own tow bars. There are adapters made to allow use of one brand of tow bar with another brand of base plate but such adapters are not made for accessory items like rock guards. If you want to tell me which tow bar model you have I can suggest a compatible...

The Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-523193-4 will connect to your tow bar utilizing the crossbar between the tabs. One style is not better than the other as far as function and fit so it mostly comes down to preference. The...

Then I recommend the Roadmaster Falcon 2 # RM-520 for your tow bar and # RM-643 for your safety cables. You can use the plugs # RM-210 when not in use if desired.

  • Available Options for Rock Guards to Protect Towed Vehicle
  • There 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.

  • Windshield Protection Recommendations For Flat Towing
  • The 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...

  • Is a Rock Guard Required when Using the Roadmaster Tow Dolly
  • You would not have to have any sort of rock guard when using Roadmaster tow dolly # RM-2000-1 but without one there is always the chance that some road debris could bounce up and hit the car. To add a rock deflector you can use the Guardian Shield mounting bracket # RM-2000-8 with the Guardian # RM-4000.
