Recently I ordered a Roadmaster Sterling All Terrain Tow Bar (RM-576) and a Roadmaster Crossbar-Style Base Plate Kit (RM-521453-4). The included Roadmaster installation instructions were very good and easy to follow. A few minor questions came up during the installation, but eTrailer's excellent installation video by Shane cleared up any confusion. Overall the installation of both the base plates and the tow bar was pretty simple and straight forward. I think eTrailer's product and installation videos are a great help in picking the right item and installing it.

Review from a similar EZ4 Base Plate in Base Plates


The order was quickly and accurately filled, shipped, and tracked to final and quick delivery. Part was a perfect fit and a simple install. This was the EZ4 baseplate for a stowaway tow bar mounting to a Jeep Wrangler JKU. I am impressed with the Roadmaster last be of tow equipment, as it shows that they have gone the extra mile in making their parts fit and make a strong and safe connection between the motor home and towed vehicle


Comments
Great. I sold the Jeep but when towing it, I felt very secure and my least worry would be a towing problem. Will buy again

Followed directions and completed job in a little over 4 hours. had trouble reinserting some pins in difficult locations. Later in the month I installed the wiring tow package. Goofed up and crossed a wire and it took me two days to get back under the truck and rewire. all is working great according to directions...……. I will use etrailer again, good service, great service representatives...……..jt

Review from a similar EZ4 Base Plate in Base Plates


The Jeep project went very well everything fit great and worked well. I really love Roadmaster products and quality and your company is the best place to purchase them. I sold the Jeep and replaced it with a new 2019 Chevy Equinox 2.0 L AWD and just purchased and installed the following items from you and installed them, RM-156-25 & RM-156-75 Battery Charge Line Kit, RM-146-7 Flex Coil Kit, RM-523193-4 EZ4 Plate Kit, RM-88333 Custom Seat Adapter, RM-751489 Stop Light Switch Kit and a RM-98160 Second Vehicle Brake Kit w/brakeaway. All these parts were in stock and arrived quickly and normal with you people, I really enjoy the o-line vidios as I do all my own installs. Thank you so much for your great service. I will attach pictures of my install, you will see how I was able to fab a bracket and attach it to the existing mount on the base plate to mount the brakeaway switch and the air connection for the brake system. I also fabricated a tail light bar as I didn't want to use mag-lights or splice into the factory lights and bulbs installed into the lights would not work as the factory brake lights will come on when the brake system is applyed and the turn siginals would not be visable. Thanks for all you do, I would and do recommend you people to everyone who needs your products. Rob


Comments
Everything is working great, I installed a base plate kit, battery charging kit, stop light switch kit, second vehicle air brake kit w brakeaway and seat adapter on our 2019 Chevy Equinox and towed it about 14000 miles behind our motor home this past year and everything worked perfect not a problem with any product. These are great products, everything fit perfectly and performed perfectly. Thank you for great service and great products. Rob

Review from a similar EZ4 Base Plate in Base Plates


I ordered this base plate to be installed on our 2020 Jeep Grand Cherokee Limited to allow it to be used with a Roadmaster Tow Bar that we purchased originally in early 2000 to tow our 2000 Jeep Grand Cherokee. Yes, 20 years later we are back into RVing and wanted to tow our 2020 Jeep behind our new Jayco Seneca Super-C motorhome. The only difference between 2000 and 2020 is the fact that we needed a brake activation system for our 2020 setup, something that wasn’t required in 2000. etrailer also sold us the Roadmaster Invisi Brake operating system which we had our local welding fabricator (also RV hitch installation expert) instal. Everything works perfectly and safely. Thank you etrailer!

Review from a similar EZ4 Base Plate in Base Plates


The base plates were easy to install (great step by step installation instructions)- it is an easy configuration for towing the vehicle. The attaching plates are well hidden from view when not in towing configuration- It is so simple to install the attaching hardware to the base plates sand fool proof -you will know you have the attaching plates properly installed every you use them-


Comments
due to the current pandemic- we have not use the product as we intended-we have use it for several miles for towing our truck- so far it shows to hold its torque and stability-little bet of rust between base plates and engagement parts- i an happy with the hardware as it was recommended by your staff- Installation instructions were impeccable- reminded me of assembly instructions for critical hardware- i am happy with its performance so far

Review from a similar EZ4 Base Plate in Base Plates


Great product for my 2014 Wrangler. Good materials, solid attachment to vehicle, and looks good. The e trailer installation video was great for assisting installation. Made the install much quicker and easier. The most difficult procedure for me was disconnecting the wiring harness on the back of the bumper. An old tack puller (or tool of similar design) would have been great for leveraging the pins out of their holes. Cutting the air dam was a slow process to ensure I didn't cut too much. A paper template to mark where to cut the air dam would make this process much simpler. Again, I can't emphasize enough how great the installation video was for making the steps easier.

This item works great. Have towed about 4500 miles using it. I couldnt be happier with the results.

Review from a similar EZ4 Base Plate in Base Plates


Anna at etrailer was most helpful getting me the correct baseplate for a Roadmaster Tow Bar I had purchased used. Very knowledgeable in the product line and recommending what parts I would need to complete my towing installation. The Roadmaster product was a perfect fit, had all the neccessary hardware parts and did not require any modifications to install it. etrailer also made several onlinr videos further showing how to install the products they sell you. The finished installation is almost invisible leaving the car looking stock until the connectors are twisted in and the cross bar installed. Great buying experience and competitive pricing keeps me returning to etrailer.

Review from a similar EZ4 Base Plate in Base Plates


etrailer service was great. Received my Roadmaster base plate in 3 days. The directions from Roadmaster were fair, but etrailer's video was excellent. I had trouble mounting my base plate as the space between the two baseplate ends were too tight. I needed to use a floor jack and bottle jack to get it on. Once it was in position everything went together fine. I trimmed the Jeep' air dam differently keeping the ends that Roadmaster wants you to cut off. I think it looks better. I also had to modify the center cut in the air dam to accommodate the breakaway switch I have.

Base plate has been working out great. Easy putting on and taking off.

Review from a similar EZ4 Base Plate in Base Plates


Hobbyist/Do-it-yourselfer: Installed on my 2016 Ford Fiesta. I was honestly amazed at how simple it was to install this product. Highly recommend watching the video on this sight that is specific to your vehicle before purchasing though. The installation process is pretty involved, and I had to take the entire front end of my car apart. It does come with very detailed installation instructions with pictures included for each step. This reassured any questions that I may have had during the installation process. It has a very snug fit. I only had problems lining up one of the bolt holes, but that was easily corrected with my Dremel. Only advice: Don't try to pry the bar into place through the bolt holes. You can/will damage the threads if you try to do this. Just use a Dremel to widen the hole on the car's crash bar very slightly. Widening the hole a small amount won't have any negative effects on the structural support of your crash bar, and it will make it even easier to install the inserted bracket.


Comments
After one year, this product has proven to be well worth the expense. We flat-towed our 2016 Ford Fiesta all the way across the country without any issues. The product worked exactly as described, and was very user friendly. Highly recommended.

Best hitch system for ease of use, durability and value. I tow a Chevy Equinox. I chose the Roadmaster all terrain hitch with an invisibrake system the previous installed. The base plate is not too difficult to install with a drill and some basic hand tools. The bolts should be properly torqued. Red thread locker is also required

Review from a similar EZ4 Base Plate in Base Plates


Installation took about 4 hrs for our 2018 Sonic RS. My wife called out the instructions and kept track of all the screws and their locations. I did the mechanics work. Some expertise is needed since the lower flange of the internal bumper had to be cut-off the entire width. A cut-off wheel does this job (great fireworks). And we used a roto-zip type tool to cut away openings in the plastic grill as needed. Lost my confidence a few times, but the customer support folks got me back on-track. Don't forget the Locktite on bolt threads and use torque wrench for mounting bolts. After a year, still tows great and held snug on some pretty rough highways. Using the Roadmaster baseplates, since I have a Roadmaster Falcon towbar

Review from a similar EZ4 Base Plate in Base Plates


Installed on a 2015 Wrangler JKU. Overall was an easy install with just one minor difficulty. The minor issue I had was with the 1/2” Tab Weldnut with rod (item # 16 in parts Diagram). This weld nut goes into a section of the Jeep frame that is boxed in and limited access to it hence the rod attached to it used for placement! This weld nut wanted to turn while tightening and was a little difficult to get it to tighten. It’s not designed for a wrench but I was able to get a 3/4 in open end wrench on the plate part of it and hold it for tightening. I think the intent in design is that it will turn up against the wall of frame and hold it from turning. It’s about 3/4 to short to contact the frame. This is a minor problem when installing the bottom side plate bolt on each side. The baseplate fit very nicely and all holes lined up perfectly. Very well constructed and finished. I trimmed the rock guard a little at a time to fit and can say that the instructions are good but say to remove a little more than needed on the depth. Take your time and trim a little at a time and trial fit it each time. Very happy with product!

  • Difference Between Roadmaster Base Plate Kits for 2019 Jeep Wrangler Unlimited
    Well you're right that it's not EZ1! In fact, Roadmaster quit using the EZ4 and EZ5 names in the baseplates. Now they're called Crossbar-Style and Direct-Connect because it's more clear. The main difference between the two styles, part # RM-521453-4 for the Crossbar-Style and # RM-521453-5 for the Direct-Connect style, base plate kits is how they connect to the tow bar. The Crossbar-Style kit uses Roadmaster's tow bars that have a crossbar to make the connection. They also fit the Roadmaster...

    Thanks for the picture of your 2019 Jeep Wrangler! Based on that we know that you do have the plastic bumper so the Roadmaster base plate kit part # RM-521453-4 is the correct fit and will work great. It's the easiest to use option to so I think you'll like it the best. The lightest weight and easiest to use compatible tow bar is the aluminum Roadmaster Nighthawk part # RM-676 which would be your best option for sure.

In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle.

  • Which Flat Towing Base Plates for 2021 Jeep Wrangler Unlimited
    By 'front tow bar', I'd assuming you're meaning base plates, is that correct? Unfortunately, the front of the 2021 Wrangler Unlimited is different enough that your old base plate kit won't work. I'd recommend the direct connect # RM-521453-5 over the # RM-521453-4 crossbar style because of it's cleaner look. It also has fewer parts which makes the hook up/disconnect procedure a bit easier. The price is the same, so why not hit the 'easy' button. This is a confirmed fit for your Wrangler...

  • Can I Use the Roadmaster Direct Connect Base Plates with Winch Attached to my 2020 Jeep Wrangler JLU
    The Roadmaster Direct Connect Base Plates # RM-521453-4 are going to install in the area that the skid plate is located, not on top of the bumper or in front of it, which is where I'm assuming most of winches are going to be mounted. If you've got an aftermarket bumper where the winch is mounted behind the bumper area and the rope winch has rollers on the front, it still isn't going to interfere. I've linked our installation video of these base plates for you to have a look at, as well.

Then for a tow bar with enough weight capacity for either vehicle the Roadmaster Falcon part # RM-522 would be a really great option. For an easy to use supplemental braking system that's removable the best option is the Blue Ox Patriot part # BRK2019. Then for wiring the part # RM-15247 would work great.

  • Mounting Location for Breakaway Switch on Roadmaster Base Plates for 2018 Jeep JL Wrangler
    The Roadmaster Base Plate Kit # RM-521453-4 referenced in your question does not feature a mounting space for a breakaway switch. This is really the case for any of the base plate kits we have available as it's really best to attach the breakaway switch and bracket directly to the vehicle and not an external attachment like the base plates or tow bar. On your 2018 Jeep JL Wrangler your best option may be to attach it to the underside of the front fascia/bumper.

There are very specific instructions in your owners manual about flat towing though that you need to follow. The Roadmaster base plate kit part # RM-521453-4 is the correct kit for your JL though.

Essentially, you'd want to match the base plates to the tow bar you're using. This involves how the tow bar attaches to the base plates. The Falcon 2 # RM-520 tow bar uses a crossbar, therefore you'd want to use the EZ 4 base plate. For a tow bar such as the # RM-677 Roadmaster Nighthawk that doesn't use a crossbar,...
