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.

Received way earlier than was projected! Installation was a snap, quality of product is as advertised and it is exactly what I need for front end protection! Even with a mud flap on the coach there was still a tremendous amount of gravel hitting the pickup! NO MORE!! Strongly recommend!er

Simple design, easy to use. Perfect fit for my towed vehicle. No longer have stones sitting on the windshield after a trip.

The actual product appears to be built quite well. However, there is little if any adjustment with Wyze. It took a lot of effort to get everything lined up to be exactly 36 inches wide.
by: SanfordTurbo08/18/2020
Installation was a breeze. Quick to mount, quick to remove, quick to store.

Hi George, all the products that I purchased from you guys arrived in a timely manner and installed on my 2017 Jeep. Good instructions and good products. I sent you a picture of my install.

excellent customer service from Quinn, on time delivery, good selection of products. would recommend this business.
by: Michael 10/20/2021
Works great with my tow bar system and protects my tow vehicle very well.
by: Arizona Slim06/24/2022
Very nice and sturdy protection for the front of the towed vehicle. Easy to assemble, attach, remove and store. I was surprised by how rigid it was even at highway speeds.
by: Ric04/09/2020
I purchased the Roadmaster Crossbar-Style Base Plate Kit w/ Removable Arms, The Roadmaster Nighthawk Tow Bar, Quick Disconnect Crossbar, Universal Hy-Power Diode Wiring Kit, and Roadmaster Guardian Rock Guard in order to tow my 2020 Ford Raptor behind my Class A. Everything bolted on beautifully and the craftsmanship was fantastic. Ordering from etrailer was easy and the parts arrived within a few days with no problem. I watched numerous [online] videos to learn how to install everything and they saved me a lot of time. Overall, I'm very happy.
by: James 09/04/2020
We have lots of stones on Idaho's roads so I wanted to protect the front end of my ranger while towing it. This guard is nothing to mount on the baseplate and should help much in preventing most of the rock chips.
by: Darren 04/05/2023
Easy installation.
by: John O.08/31/2019
I received the RM-400 on time, watched the installation video and installed it. I haven't used it yet but I'm confident it will do the job keeping the front end of our car protected while towing behind the motorhome.
However, the box didn't have the thumb screws.
by: Tim 08/08/2022
The parts and hardware all arrived in good shape despite the beat up condition of the box. It was easy to assemble and provided everything I needed to mount to my Roadmaster Tow dolly. Easy to remove the guard and fold up for storage inside. It was a bit expensive, but I'm hoping it will save the front hood and windshield of my Mini.

The rock guard is easy to install. It provides a good amount of protection for the vehicle. It is light fairly light weight sturdy.
I use it on my Ford Xplorer along with the roadmaster rowboat and vehicle brackets
by: Cookie12/12/2013
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.
by: Gene R.04/01/2015
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.
by: Ronald08/20/2019
Once you install the guardian carrier installing the Guardian is a breeze. The important step in the installation of the carrier and the guardian is driving your car onto the dolly to make adjustments to the carrier and guardian reference your vehicle. After you get it all together lt looks good and works. I'd buy it again.
by: Patrick 01/21/2022
This rock guard will deflect anything you might kick up. Be sure to get the right guard for your tow hitch.
by: Wayne10/17/2020
The product arrived in two business days, absolutely amazing. Installation was easy and works great. What else can you say? Roadmaster items are well engineered and and always work together when they say it does. As long as you do the research on products, etrailer gets it to you fast.
by: Doyle07/05/2020
I towed my 2019 Silverado Pickup behind my Motorhome from Lincoln, NE to Yellowstone National Park and everything worked great and was easy to hook up.
by: Dennis G10/10/2015
The Rock Guard that came is as I ordered. As i had faith it would be. My first time ordering from them. They told me that it was in stock and that it would be shipped the next day and when it would arrive....It all took place...Keep up the good work.
by: Bill B.08/11/2012

- Flat Tow the 2013 Honda CR-VThe Roadmaster InvisiBrake Supplemental Braking System, # RM-8700 can be installed on your 2013 Honda CR-V to be towed with your motorhome. Provided your motorhome is properly arranged and has the tow capabilities of the Honda's vehicle weight. If you select the Roadmaster Falcon All Terrain, # RM-522, you will need the Roadmaster Crossbar-Style Base Plate Kit, # RM-521567-4. The RoadMaster Falcon 2 and Falcon All-Terrain Combo Towing Kit with Straight Wiring, # RM-9243-1. The Roadmaster...
view full answer... - Will the Guardian Shield Mounting Bracket RM-2000-8 Fit a Kendon Motorcycle Trailer?I can definitely say the Guardian Shield Mounting Bracket # RM-2000-8 will fit the # RM-4000 Roadmaster Guardian Rock Guard. However, to mate this to a trailer or tow dolly that is not a Roadmaster, you will need to double check and make sure your Kendon trailer has a tongue/frame tube with a width of 3-1/4 inches or less. If your trailer follows this guideline, you are good to go. If you do not have a tongue/frame tube that is this size, you will most likely need the Roadmaster Guardian...

Your F-150 has a basic curb weight that is between 4,021lbs and 5,540lbs depending on your body style and powertrain. If you are close to or exceeding the 6,000lbs I recommend the Roadmaster Nighthawk All Terrain # RM-676. This bar is rated for 8,000lbs. As you want to use the Roadmaster...
view full answer... - Tow Bar Rock Guard that Fits etrailer Tow BarSince you have an etrailer tow bar we do have a rock guard that fits it with the Demco Sentry Deflector part # DM9523135. There isn't a Roadmaster rock guard that fits what you have.
view full answer... - What is Difference Between EZ5 and EZ4 Roadmaster Base Plate Kits for 2019 Jeep WranglerFor your 2019 Jeep Wrangler the EZ5 kit part # RM-521453-5 is a fit and what makes it unique to the EZ4 part # RM-521453-4 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 # RM-4000...
view full answer... - Does Roadmaster Rock Guardian Work with Roadmaster Tow BarYes the Roadmaster Rock Guardian part # RM-4000 does work with the Roadmaster tow bar setup you have on your 2006 Lexus GX 470. I attached a review video for more info on this as well.

They are not compatible together. Unfortunately, they use the same attachment areas eliminating the possibility of them working together. While this may not help all the time using a Rock Gaurd like the Roadmaster Guardian Rock Guard part # RM-4000 can help to protect your vehicle from damage caused while flat towing...
view full answer... - Can the Roadmaster Stowaway Storage System Store Both a Tow Bar and The Guardian SimultaneouslyYou can use the optional # RM-222 car side quick disconnects to store both the Guardian # RM-4000 and a tow bar with quick disconnects. The Roadmaster Stowaway Storage System, item # RM-4000-40, can be locked to the motor home drawbar with an optional locking hitch pin like the Trailer Hitch Receiver Lock - Stainless Steel Flush Design for 2 inch Trailer Hitch Receiver, item # e98882.

If you do not have the # RM-201 quick disconnects you will need them to adapt the Guardian Rock Guard to your tow bar setup. The Roadmaster Guardian 2nd Vehicle Kit, item # RM-4000-1, is designed to attach the guardian to a second vehicle with quick disconnects.

I suggest the option you are...

The first is the Roadmaster Direct-Connect Base Plate Kit # RM-523188-5. With this kit you do have removable arms that allow for a clean look when you are not towing your Envision. This will also give you the faster connection meathod as it does not require the installation of the crossbar.

I recommend that you verify in your vehicle specific owners manual for flat tow however, if you have a 4x4 model with 2-speed power transfer unit then flat towing is not an issue and the steering wheel will not be locked when arranged for towing with the engine off. It is suggested that you ensure, through the setting menu, that the auto parking brake feature is...
view full answer... - Availability of Blue Ox Adapter for Roadmaster Guardian Rock Guard RM-4000Thank 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 rock...
view full answer... - Roadmaster Guardian Rock Guard RM-4000 RecommendationThe Roadmaster Guardian Rock Guard # RM-4000 is a great choice for a way to protect the front end of your vehicle as it is being flat towed. This one may not be as tall as the one you currently have but due to how close the towed vehicle is to the tow vehicle the taller guard would not be necessary. The rocks that would end up thrown from your tow vehicle wouldn't end up high enough to clear this guard. It will work well for you. If you check out the reviews of this product you will see...
view full answer... - Solution for Towing 2017 Toyota Prius Behind MotorhomeYou are correct, the 2017 Toyota Prius that you have can only be towed on a dolly behind a motorhome. Good news is it won't put miles on the vehicle since the drive wheels will be on the dolly. I like dolly setups over tow bar setups for a number of reasons. The install time is considerably less, you can easily transfer the towing setup to a different vehicle unlike base plate kits that are vehicle specific, and you don't put miles on the vehicle. The price isn't that different either when...

- Replacement Mounting Hardware for Roadmaster Guardian Rock GuardThe Roadmaster Guardian Rock Guard # RM-4000 fits on Roadmaster crossbar style base plates with the Hardware # RM-4000-1.

It sounds like debris is getting kicked up from the sides of the rear wheels as much as it is from behind them. The only way to really reduce that would be fender skirts to partially block the sides of the tires but those would likely have to be custom made. There...

The face of the seal and bearings should have a number stamped into them but it can wear over time. To get to the inner bearing you will have to remove the grease seal so that you can get to it so the hub will have to stay off until you get replacements. If the part number has worn away then the next step would be to measure...

Depending on what base plates and tow bar you have for your 2006 Toyota Matrix, we have options. The Roadmaster Guardian Rock Guard, # RM-4000 fits all Roadmaster tow bars with quick disconnects. The Sentry Deflector for Demco Tow Bars is # DM9523135 and the Blue Ox KarGard Towed Vehicle Protector, is # BX8870.

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...

The screen can easily store on the tow bar when not in use but the Rock Guard needs to be removed from the tow bar when not in use. It does fold up for easy storage though.
