Features to know about

Made for a Clean Front End: Hidden Bracket Design with Removable Drawbars

When you’re not towing, you can keep your front end looking clean. The hidden bracket design of the Roadmaster EZ Base Plate Kit leaves the setup virtually invisible once the drawbars are removed. The remaining brackets sit tucked back within the grille, keeping them out of sight and protected from scrapes and scuffs. It’s a simple way to keep the front of your vehicle looking stock without bulky parts sticking out.

Quick Connection Every Time: Twist-Lock Attachment System

Hooking up doesn’t need to take long or require extra tools. The EZ series’ Twistlock system lets you insert each drawbar into its bracket and lock it in place with a quick twist—no pins or clips required. When it’s time to unhook, a twist and pull releases the bars just as easily. This makes connecting your tow bar fast and repeatable, whether you’re in your driveway or at the campsite.

Strength You Can Trust: Computer-Cut, All-Steel Construction

Built to handle the demands of long-distance towing, this base plate kit uses computer-cut, all-steel construction for precise fitment and exceptional strength. The black powder coat finish resists corrosion and keeps everything looking sharp after miles on the road. That solid build means you can tow confidently knowing the load is properly supported by durable steel hardware bolted to your frame.

Simplified Setup: Bolt-On Install with Included Hardware

No welding required here—the kit installs directly to your vehicle’s frame using the provided hardware. The custom brackets ensure a perfect fit, and clear instructions walk you through each step for a straightforward installation. Add fishwire part # C58400 (sold separately) for a complete install if needed. Once tightened down, you’ll have a strong, secure connection ready for your next trip.

Works with Your Favorite Tow Bar Setup: Roadmaster System Compatibility

This base plate kit is compatible with Quick Disconnects and all Roadmaster tow bars, so integrating it into an existing setup is easy. Whether you’re running an All Terrain, Falcon, or Blackhawk series bar, it connects right up without any hassle. It’s a flexible choice if you already own Roadmaster towing gear or plan to expand your setup later on.

Great installation instructions and video. Was an interesting and fun project installing in our Mini-Cooper



by:

I installed this base plate system on my 2014 Jeep Grand Cherokee Limited this weekend. My Jeep had tow hooks which were basically removed and replaced by the base plates in the same location. No modifications to the grill were required and the base plates are no more noticable than the tow hooks were.
Installation was straight forward. Roadmaster forwarded a PDF file of the excellent color instructions with my order confirmation. I was able to view the photographs on my ipad and zoom in where necessary to get more detail.
Overall I would rate the Roadmaster product, instructions and customer service 5 star in every way.



by:

Very good product at a great price. Instructions and video are for a 2013 terrain and things were a bit different on my 2015. When all screws and clips are removed the front piece cannot be just pulled forward. There is a rear facing clip and you have to pull to the side to remove from this piece. (pics attached)There was no PS cooler attached in front on mine. Remove washer bottle totally which consists of 2 nuts and 1 bolt otherwise you will never get back up plate for top brackets in. If you remove horns it also makes installing the top brackets much easier.



by:

Installed on 2005 mini cooper convertible. Choose this base plate for our mini since it provided highest attachment height for tow bar (12 inches off ground, only requires 3 inch drop from back of RV), and attaches to mini frame more substantially that blue ox. Installation directions are nearly perfect, we had to widen holes on passenger side to line up with frame. Modification was approved by Roadmaster.



by:

Very well constructed. Fitting right side took some adjustment, I had to clearance the lower member hole in order to fit the bolt.
I installed the base plates myself, after the prospective mechanic claimed this was the incorrect fitment. Subsequent calls to Roadmaster produced a "No Fit" pronouncement, in spite of the lookup and even the printed instructions. Undaunted, I proceeded, and the fit was successful. YES, this DOES fit a 2007 Mini Cooper S Convertible.



by:

Easy to install for the do it yourselfer. Good quality and fit. etrailer customer service was great too.



by:

I had my tow car blow its engine in South Dakota while on vacation. It needed to be replaced. I bought a used car and ordered a tow bracket for it and had it shipped to one of my destinations so I could install it there.
Unfortunately that car also broke down but I was able to return it. I asked to return that bracket and etrailer accepted it back.

I found a different car and ordered the bracket for it plus a wiring kit. etrailer shipped those and they were there when I got there.

They were easy to install and fit exceptionally well. After having my wife drive the new tow car for 1000 miles we were happy to get back in the motor home while we traveled.



by:

The installation on this was surprisingly quick on my 2011 Fit (base/non-sport version). Everything fit well (no pun intended).

A few minor changes over the video as my car was slightly different:
- I didn't have to trim anything on the air dam -- the tubes lined up perfectly with the slots on my grill.
- There was a in the wheel on each side where the plastic bumper meets the steel body panel. I didn't realize they were there (they're hidden somewhat) so I ended up cracking the hole this screw was in, but everything came back together nice and tight anyway.



by:

It does what it's supposed to do, which actually seems to be special these days. In all seriousness we purchased this for out Liberty, which blew it's ending the first time we tried to go on a big trip. We had it taken off of that Liberty and put on another and that's what it was on for our tip from AZ to Chicago. We have connected and disconnected probably a dozen times and took the arms off to drive around Chicago. It works just like it should and it is nice to not have to worry about at least one item. Hightly recommend this system.



by:

The Roadmaster base Plate kit does what it was designed to do. A difficult install as the Smart ForTwo did not lend itself to an easy base plate engineering design.
Installed it myself though with help from the instructions and etrailer on line instructions. I like the finished base plate. It is barely visible protruding only slightly from the black lower radiator grill (see photo)



by:

Very happy with this product. Installation was pretty easy. I see no reason to pay someone to install this. True you have to take the bumper off and a large metal support beam but it was pretty easy. You just have to take it slow and not get frustrated. The bumper on the Honda Fit is held on with a gazillion little plastic clips and snap joints. Everything fits tight on a Honda so you have to be patient. My only complaint is they don't give you the exact torque settings. I had to consult a shop manual to get the correct torque values. They give a table at the end of the instructions that gives common torque values for various bolt sizes. I thought that was lame they could have given the correct value from the shop manual. Certainly not enough to lower my rating. This bar is awesome and when the drawbars are removed the base plate is almost completely hidden. My wife wanted nothing to show on the front of the car. She was very pleased with it.

In the picture attached the bar is almost completely hidden. All you see are two small black circles. It takes about 2 seconds to mount the drawbars, just twist and go. VERY sturdy. I tow my Honda behind the motorhome with confidence.



by:

very well made and just getting pickup ready for flat towing. Fast shipping and excellent service. Highly recommend.



by:

It was a very easy install and it did great. Only got to use it for 2 months though before a semi drug his trailer across the back on my toad and totaled the vehicle.



by:

Parts came very quickly. The base plates are really well make and of heavy material. If you watch the video it is a breeze to install. Make sure you have some new clips for your bumper as the old ones will break, not all but some. I ordered clips from Amazon. I used a vibrating saw with cutting blade and it did nice job cutting plastic bumper cover.



by:

I received the base plate for my Miata at 4:30 Monday by 7:00 it was installed and ready to go.A great product fit very nicely.Ordering and follow up went great can’t wait to try it out Just need to decide on the tow bar we will use.The Falcon or Sterling .Thank you for a great product and service.



by:

Installed on 2014 GMC Acadia. Very sturdy and heavy duty base plate. I installed it myself. You will need a little automotive knowledge and more tools then the average do it yourself-er. It took about 6 hours, by myself. It looks more intimidating then it turned out to be. You can't see it when not in use which makes it nice for the wife, since it's her car.
Pictures show the tow bar adapter. Sorry, no pictures of adapter removed.



by:

easy to follow instructions, took about 3 hours to install. paper template for holes in facia would be great .



by:

Roadmaster base plate for 2010 GMC Terrain. Very detailed instructions, great videos. Product was as described, no holes to drill, just replace factory parts with Roadmaster parts. Everything went together very well. I used the instructions supplied along with the video on my laptop. Hardest part was popping the bumper shroud back on due to colder temperature. I have a fair bit of experience with rebuilding classic cars so have lots tools and reasonable mechanical ability.



by:

Purchased the towing adapter for my GMC Terrain a few week ago, received it on time & boxed not damaged. Watched the videos’ about three time on how to do it myself and started one evening and finished it the next morning about three hours with Beer Breaks, LoL. All the parts fix perfectly, had no problems with any of the parts, Product is real sturdy and if you don’t know where to look at the bumper you will not see the hide away receiver brackets. Very nice product, do it yourself and save
Up loading two photos if it will let me one is with hide away brackets installed and the other one you can see is my complete tow bar attached to the hide away brackets



by:

Seems like a very well-made sturdy product. Instructions were good however the holes did not quite lineup like they were supposed to so I had to do some mild to moderate modification. I like the way it looks without the towbar on the base plate. It’s fairly well hidden.



by:

The baseplate fit perfectly and the video was very helpful



by:

Thanks for being a great knowledgeable person about this tow set up. It fit perfect and the directions made it a no brainer



by:

Installed without a hitch! Matches up perfectly with the Roadmaster Stowmaster towbar we already had. Beautiful!



by:

Many reviews for this base plate said they could not hook up the U bolts. I had no problem using the U bolts. I did not tighten any bolts until I had them all in place. Then, I tightened all the nuts and bolts. I marked them with paint so I could see if any of them backed off. After a year, all of them are still tight. We towed our mini 4,000 miles in the first year.

Not very easy to install but great qual ity!!

  • Why Go With a Nicer Tow Bar than the Curt Tow Bar # C19745
    I really wouldn't ever recommend the Curt tow bar # C19745 unless it was a one time use situation and the person was okay with drilling holes in the front bumper of the vehicle. It's also very difficult to connect and disconnect. If you went with a much nicer Roadmaster like the Falcon All Terrain part # RM-522 you can use a base plate kit that mounts directly to the frame of your 2007 Volkswagen New Beetle like the Roadmaster EZ part # 521232-1 which has removable arms and provides a...

  • Choosing Between Roadmaster or Blue Ox Products to Flat Tow 2007 VW Beetle
    Either Tow Bar and Base Plate set-up would work well for you. In my opinion, Blue Ox has a slight edge. Their tow bars include the safety cables, while Roadmaster does not. On many applications, their base plate kits require less modification of the vehicle. I have been told by folks that have used both Roadmaster and Blue Ox systems that the Blue Ox triple lug method of attaching the tow bar to the base plates is easier and more hassle-free. The Blue Ox Alpha, part # BX7380 is a good...

  • Recommendation For Adapted Roadmaster Blackhawk Tow Bar To Fit Roadmaster Base Plates
    If you have the original Blackhawk tow bar parts, you would just convert the tow bar back to original as the Roadmaster Blackhawk is compatible with the # 521232-1 base plates. If you don't have the original parts, you can simply use the Roadmaster Tow Bar Adapter # RM-032 to make your Demco Adapters compatible with your Roadmaster base plates. Your other option is to use the # RM-9200-6 if you have the Blackhawk 2 and the Roadmaster Quick Disconnect Tow Bar Base Assembly # 910021-00...

  • Recommended Base Plate for a 2007 VW Beetle
    Yes, the Roadmaster EZ Base Plate Kit item # 521232-1 is compatible with the Guardian Rock Guard item # RM-4000 and the Defender Protective Screening item # RM-4700. This base plate is confirmed to fit your 2007 VW Beetle and will work with your Roadmaster Nighthawk Tow Bar item # RM-676. It sounds like you already have the Quick Disconnect Crossbar Assembly for Roadmaster Motorhome Mounted Tow Bars item # 910021-00.

  • Recommended Tow Bar for Roadmaster Base Plates on 2013 Hyundai Veloster
    I'd recommend the Roadmaster Falcon All Terrain Tow Bar, part # RM-522. The non-binding and self-aligning arms mean that you won't need to make sure the car is perfectly lined up behind the vehicle and the pavement or ground is flat as a pool table. The tow bar has a 6000 lb capacity, which will work perfectly for your Hyundai Veloster and is fully compatible with your existing Roadmaster Base Plates. I've linked you to a product demonstration video featuring the Roadmaster Falcon All-Terrain...
