Features to know about

Built for a Clean Front End: Hidden EZ Base Plate with Removable Arms

When you’re not towing, this setup keeps your vehicle’s front end looking clean. The hidden bracket design tucks neatly within the grille, leaving nothing sticking out or catching your leg when you walk by. Once the drawbars are removed, the brackets are virtually invisible and protected from scrapes and scuffs, giving a factory-finished look every time.

Hook Up and Go: Twist-Lock Connection Without Pins or Clips

Connecting your tow bar is quick and simple. Just insert the drawbars into the brackets, twist to lock them in place, and you’re ready to roll—no pins or clips required. When it’s time to disconnect, twist again and pull them out. This twist-lock attachment makes it easy to line up and hook up solo, even in tight spaces.

Solid by Design: Computer-Cut, All-Steel Build for Strength

This base plate kit bolts directly to the frame with no welding required. Its computer-cut, all-steel construction provides exceptional strength and durability over long miles of towing. A black powder coat finish adds corrosion resistance for long-term reliability and a clean look that lasts.

Ready for a Straightforward Install: Custom Fit with Included Hardware

Each kit comes with clear instructions and mounting hardware to make setup straightforward. The custom base plates ensure a perfect fit for your vehicle’s frame while staying compatible with Quick Disconnects and all Roadmaster tow bars. Fishwires (C58400 – sold separately) are required for complete installation, so you’ll have everything lined up right from the start.

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.

I towed my Mini Cooper on a 5000-mile trip this summer. The Base Plates worked great. I had to replace the water pump on the Cooper this required removing and reinstalling the base plates. I inspected them, and after two years and 9000 miles of towing, they are in perfect shape.

I towed it 200 miles of winding mountain roads. Worked perfectly @JamesD

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

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.

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.

2014 Jeep Grand Cherokee
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.

Did you have to do any drilling on your vehicle to mount this system?

Yes, there will be some drilling involved in the installation. Check the instructions link on the product page for more information about the drilling that will be required. I believe it will just be four 1/2 inch holes.

The Roadmaster baseplate and Falcon tow bar are working great with our 2014 Grand Cherokee and Endeavor motorhome. We are in the middle of a 1500 mile trip and have had no problems with the equipment. I have decided that I need to purchase a braking system for the Jeep. Thinking about the Invisi Brake, primarily because it is made by Roadmaster and I had a great experience with your companys customer service when the 2014 Grand Cherokee baseplate kit was being developed. Thanks for the good work.

Thanks for the follow up, very happy to hear that you are pleased with your Roadmaster Base plates. If you are considering the Invisibrake # RM-8700 as a braking system this is a great choice. The installation is a long and involved process and if you are looking for a more simplified installation you might like another Roadmaster product such as the Even Brake # RM-9400. This will serve the same purpose as the Invisibrake, but the portable unit will have to be removed after flat towing your Jeep where the Invisibrake is permanently installed in your tow Jeep.

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

Have been using this tow adapter now for a while and everything works out fine, Easy to connect. I did purchase the Wiring harness from the tail lights to the front of the car instead of making it as I usually do and the connection to the RV from that connection and glad I did, the wiring harness also went easy and very fast.

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.

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.

I have towed my Terrain about 3500 miles with no issues. It tows and tracks extremely well. I put red paint marks on the bolts that are easily seen, so that I can see at a glance if any bolts have loosened up. I use a Roadmaster All Terrain tow hitch and SMI Duo braking system.

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.

2010 Honda Fit
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.

Even I had to wait almost 2 months, I'm so grateful that I got the Roadmaster base plates and tow bar..:) It is so easy to be mounted and to operate with it... Thank you for the good product.... P.S You don't need to cut anything from the bumper plastic facial...so you can just skip that part from the instructions!

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)

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.

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.

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.

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.
