Very happy with the base plate- as well as the amazing installation job done by etrailer. Has been a job to own and use allowing simple efficient towing of my car behind my motorhome. If I had any complaint it would be to ask Roadmaster to do a better job on the paint. the darn thing rusts so fast, it's hard to keep up with. But, still a five star product

Fit perfectly on our Chevy spark

The base adapter for my Chevrolet Spark, that I ordered, arrived in less than a week. The instructions were very helpful. Proceeding carefully it took about four and a half hours to complete the installation and it fit perfectly. The adapter appears very well made and is by far the most robust part of the whole vehicle.

Review from a similar EZ4 Base Plate in Base Plates


Had Base Plate installed today, shop gave me 2.5 hr labor time. I returned just under 2hrs and they were backing my car out the shop. They parked it facing me. I told the Mechanic "That was quick" He said that's because it wouldn't fit. I was disappointed and asked what do I owe you for your labor> He laughed out loud and said it on there, but hard to see. I was so surprised and pleased you have to just about get down on your knees and bend down to see it. took me about 8 min to install everything and connect it to the Tow vehicle. I'm very pleased with it.

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!


Comments
Excellent! We have towed the Grand Cherokee with it for over 17,000 miles since installation, with no operational issues. From NW MT to west coast of WA, to Rockport, TX, to Duluth, MN and back in three separate trips.

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 installed this kit on my 2015 Honda Fit. The instructions are very good, however, there are a couple of "snags" to watch out for. You might have to enlarge the holes on the blind hole part of the bumper installation in order to get all of the mounting bolts to align. The other recommendation I have is NOT to use the Loctite "red" thread compound on the blind hole bolts where you cannot get a wrench on the inside. The Loctite will dry too fast and cause issues tightening the bolts on those areas. They have lock washers anyways and you can use the Loctite on the bolts you can get a wrench on the backing nut mounts. I have been towing for months now and I am very happy with it, especially the crossbar style. You will have to purchase the crossbar separately. It's more weight and a little clunky compared to the direct attachment but it allows you to disconnect in some tough situations by pulling the crossbar off while one arm of the tow hitch is still attached. I use an Falcon All Terrain tow bar so I can release the tow arms in uneven conditions. And I have encountered all types of uneven ground, it really makes disconnect of the TOAD very easy.

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.

This was a straightforward install. The instructions were easy to understand and follow. All the necessary parts and hardware were included. It is pretty well hidden once installed. I highly recommend this base plate and etrailer.

This was my 4th install for a dingy (with 4 wheel flat towing) in the last 20 years. This install is for a 2018 Jeep Grand Cherokee, Overland. The New ROADmaster 90* twist & lock removable base plates are REALY Awesome! So much much easier & faster than installing & removing locking pins! One picture shows a Brush guard from ROADmaster no longer available.

Review from a similar EZ4 Base Plate in Base Plates


This tow bracket base was a little tough for an old senior but very straight forward install. Everything went as the instructions said. The product is very well built and looks good where it comes through the front bumper cover. As usual the customer service and fast shipping from etrailer is exceptional.
I have had many purchases here and it's always great. I give etrailer itself 5 stars as well as the products.

Received my Roadmaster base plate and wiring kits for my 2020 Buick Envision a day early. Just as in the past when I ordered 2 base plate with wiring kits all parts with clear instructions was in the box. All the personnel has been very courteous. I got Lori B.as my salesperson. She was very friendly, knowledgeable, and made ordering easy. When I had a question she responded fast to my request. Thanks Etrailer for a job well done.

Review from a similar EZ4 Base Plate in Base Plates


I purchased this EZ4 base plate to work in conjunction with the Falcon2 tow bar. It fit perfectly on my Wrangler Unlimited, and is tucked mostly out of site when not used. The two baseplate arms bolted to the cross bar of the Falcon2 are easily removed and stored away when not in use. Installation because of the weight and tight fit to the Wrangler frame, was found to be much easier with two people.

Review from a similar EZ4 Base Plate in Base Plates


Very Happy! The shipping was fast; 3 days, including Thanks Giving. I was able to instal the base plat myself, just following the installation video on their web site. I watched it a couple of times while I was waiting for delivery, and then followed it step by step during installation. I wouldn't have dared attempt it myself without the video. I also installed the Tail Light Wiring Kit with Bulbs-RM-155 using the same method. Everything went without a problem. I will be buying from eTrailer again.

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


Installed it myself on a 2017 Ford Focus. Watched a few videos on how to pull front bumper and install mount. The hardest part was making the holes in the steel front bumper. I like the fact I can remove the outside mounts that the hitch mounts to. I’ve pulled the car about 5,000 miles behind the rv with no problems.

Delivery was great right part but this is the 6th baseplate I’ve installed and the instructions could be better. The pics could be better showing some bolt locations nothing is written about cutting inner fender but then look at pics showing they cut them the inner fender biggest problem.

I checked with the manufacturer and the instructions could have been an older set. The manual will be the most up to date for the installation on a 2020 Toyota Tacoma.

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.


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

I bought all of my products for flat towing my 2014 Jeep Cherokee for etrailer and I couldn’t be happier. The service was exceptional, the pricing was right, and when I did have a problem, they were right there to take care of it. When I need more goodies for the RV, I will be back!!!!

I am not quick to review a product, it's been over a year since I purchased and install this hitch.
After using this for a year, I found this to be excellent.
Absolutely no problems.
My wife and I installed it with no problems at all,,, easy to do.
The videos was detailed, letting feel comfortable in doing the job.

Sadly, selling the vehicle,, now we don't have it any longer.
However,,,
With our new vehicle, I am again going to purchase from this same company.
This fit our 2004 Jeep Wrangler X

  • Preparation Steps to Flat Tow 2018 Chevy Spark with Manual Transmission
    When it comes to flat towing any vehicle, that auto maker generally gets the final word on the preparation steps that are required. If Chevy made revisions to the original printed manual in the form of the add-on flyer then I would suggest you observe the information in the most recent material. Some vehicles do require a battery disconnect. Page 270 of the online manual does indicate "1. Position the vehicle to tow and then secure it to the towing vehicle. 2. Shift the transmission to...

  • Base Plate Kits that Fit 2017 Ford Edge
    For your 2017 Ford Edge we have base plate kit options but the configuration of the Edge is how you'd pick out the correct kit. I attached a link that has all of the several different styles of vehicles your Edge might be from the various trims to with or without active cruise control. You'd need to select what you have so that you can see the available options. You'd also need to check your owners manual under recreational towing to see if there are any restrictions there too.

  • Can The Roadmaster Base Plate Kits Be Used With the Ready Brute Elite II Tow Bar System?
    Yes, the Roadmaster Crossbar-Style Base Plate Kit(EZ4) # RM-523185-4 for your 2017 Chevrolet Spark is compatible with the Ready Brute Elite II tow bars. I recommend using the Roadmaster Direct-Connect Base Plate Kit(EZ5) # RM-523185-5 so that you will not need to have a Crossbar # 910021-00 on the front of your Spark. You are correct that your Spark does not require the battery to be disconnected when being flat towed.

  • Why Does Battery of Vehicle Need to Disconnect Sometimes when Flat Towing
    For a lot of vehicles you have to have the ignition in the ON or ACC position to unlock the steering wheel so that it can steer behind the vehicle flat towing it. Normally this would drain the battery fairly quickly so the solution is to unhook the battery with the ignition in the correct position to allow the wheels to steer and not drain the battery at the same time. We have the Roadmaster battery disconnect kit part # RM-766 which will automatically disconnect the battery of the towed...

  • Recommended Trailer Hitch Receiver for 2017 Forest River 2380 FTD to Flat Tow Chevy Spark
    For a motorhome, you won't use a custom fit hitch receiver. Instead you will use an RV hitch receiver. I recommend the Adjustable Width Trailer Hitch Receiver for RVs, 22" to 66" Wide # C13704. This hitch is rated to pull the Chevy Spark without any issue and no extension is necessary.

  • What are the Differenced Between EZ4 and EZ5 Roadmaster Base Plate Kits for 2016 Chevy Spark
    The difference between the EZ4 Base Plate kit part # RM-523185-4 and the EZ5 kit # RM-523185-5 is that the EZ4 uses twist-lock drawbars while the EZ5 uses drawbars held in place by pins and doesn't require the use of a crossbar. I would go with the EZ5 if it were me since not having to use the crossbar is just one less thing to worry about. 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....
