Features to know about
Made for a Clean Front End: Virtually Invisible Base Plate Design
When you’re not towing, the front of your vehicle keeps its clean look. The hidden bracket design leaves the mounting points tucked away within the grille where they’re protected from scrapes and scuffs. With the drawbars removed, there’s no bulky hardware left in sight—a big plus if you value a factory-style appearance when parked or driving around town.
Quick Hookup and Release: Twist-Lock Removable Arms
Connecting your tow bar is a simple twist-and-go process. Each removable drawbar inserts into the bracket and locks in place with a quick twist—no pins or clips to fumble with. When you’re done towing, just twist again and pull them free. The smooth mechanism makes it easy to hook up and disconnect even when working alone, saving time at camp or on the road.
Built Strong for Long Miles: All-Steel, Computer-Cut Construction
This kit bolts directly to your vehicle’s frame for a solid connection that spreads towing forces evenly. The all-steel brackets are computer-cut for precision and finished with a black powder coat that holds up against corrosion and road wear. The robust build gives confidence for long-distance towing setups that see thousands of miles on the highway.
Straightforward Setup: Bolt-On Installation with Included Hardware
Installing this base plate doesn’t require welding or complicated fabrication work. Each kit includes instructions and mounting hardware so you can bolt it up securely using common tools. The custom-fit design lines up with your vehicle’s frame points, keeping the process simple for anyone taking on the job themselves in a home garage.
Compatible with Roadmaster Tow Bars
If you already use a Roadmaster tow bar, this setup fits right in. It’s compatible when used with the quick-disconnect crossbar (910021-00, sold separately), linking your existing towing gear into one straightforward system. That means less guesswork when pairing parts and more confidence every time you roll out.

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.

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.

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?
Patrick B.

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.

- Parts Needed to Flat Tow a 2004 Volkswagen Beetle Behind an RVIt sounds like you do not have an S or non-Turbo S model Beetle. The Turbo S Beetles come with a 1.8 liter turbo motor and a speed activated rear spoiler. You would probably know this already if you had an S model. The Roadmaster Base Plate Kit # 521225-1 that you referenced would be the correct base plate kit if you had a Type S of a standard model Beetle. I checked with Roadmaster to confirm this. The Roadmaster Tracker Tow Bar # RM-020 and Quick-Disconnects # RM-201 that you also referenced...

For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground.

For tow bars, I recommend the RoadMaster Falcon 2 Tow Bar # RM-520 which has the convenient Autowlok locking mechanism and quick disconnects for effortless, one-person mounting and removal. And it is made to work with the recommended base plate. Another option is the RoadMaster Falcon All Terrain Tow Bar # RM-522 which features the hassle-free Freedom Latch which lets you...

Apart from the tow bar itself, flat towing also requires a set of base plates, a wiring/lighting kit and a supplementary braking system for the towed car. Also required are safety cables, and often a high/low hitch adapter to keep the tow bar level. Each of these items is reviewed in detail in the linked article on flat towing.

view full answer... - Will Draw-Tite Tow Bar Work On 2002 VW BeetleI do have an option for you but the Draw-Tite Tow Bar part # 63180 isn't designed to be used with base plate, the bracket that comes with is supposed to be welded to a steel bumper or you can bolt it to the core support with bumper removed in some cases. For a cost effective compatible setup, I recommend the Roadmaster EZ Base Plate Kit part # 521225-1 with Roadmaster Tracker Tow Bar part # RM-020.

You would need several items though. To start you would need a base plate kit. For your 2004 Volkswagen New Beetle you would want the # 521225-1. 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.

For the Beetle, you would want to use part # 521225-1. For safety reasons, we cannot recommend using base plates other than those Roadmaster recommends for the vehicle. You are towing a 2700 pound vehicle behind a motorhome attached essentially by a few bolts. It is imperative that the junction between the tow bar and the towed vehicle be as...
