Features to know about

Made for a Clean Front End: Hidden Crossbar-Style Design

If you want a clean, factory look when you’re not towing, this setup delivers. The crossbar-style brackets sit far back on the frame so the front end stays uncluttered. Once the removable drawbars are out, the remaining brackets are virtually invisible, tucked inside the grille where they stay protected from scrapes and scuffs.

Quick Hookup and Disconnect: Twist-Lock Removable Arms

The drawbars attach and remove quickly thanks to the twist-lock system. Each arm clicks into place when inserted, locking securely for towing. When you’re done, pull the built-in rings to unlock, twist them back out, and your front end is clear again. It’s simple enough that one person can handle it without a struggle.

Solid Build for Long Miles: All-Steel, Computer-Cut Construction

This base plate kit is built from computer-cut, all-steel components for exceptional strength. The black powder coat finish adds durability and corrosion resistance so it keeps its integrity through thousands of miles of road time. The plate mounts directly to the frame with no welding required, giving you a sturdy connection that holds up trip after trip.

Ready to Fit and Go: Custom Mounting and Compatible Connection

The kit includes custom-fit base plates designed for precise alignment with your vehicle’s frame points, so installation is straightforward with the included instructions and hardware. It’s compatible with Roadmaster tow bars when used with the quick-disconnect crossbar (910021-00, sold separately). For installation, fish wire bolt leaders (80101-1, sold separately) are required to complete the setup.

Note

To remove, simply twist the arms back and pull them out. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs.

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.

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.

Baseplate did not fit vehicle. Apparently it was manufactured icorrectly. All other baseplates for this vehicle were also manufactured improperly so engineering had to come up with new install procedures. Took a week to make that happen. Also, received new Easy Connect modules that are identical to one I already had.

I checked with Roadmaster directly and it is not that the base plates were manufactured incorrectly, it is that Ford made running changes to the vehicle. In the instructions it is mentioned that you will want to use all the bolts and parts in the kit. If the bolts or other fasteners are no longer the corret size due to to changes in the vehicle then you will want to make sure that the base plate is securely fastened to the vehicle. I have not had other reports on other Ford Fiastas where this was an issue.

Your products have been perfect, good fits and quality products. The towing base plate for my ford Fiesta fit with little modification and the ability to use standard tools. The instructions were right on. The tail light wiring kit also was easy and works great.
Shipping was fast and delivery arrived as indicated.
I will continue to do business with you.

After a really bad experience with another brand of baseplate, I trust the Roadmaster. The Roadmaster base plate attaches to the car's frame with TWO bolts on each end. My last base plate, a different well known brand, only had one bolt on each end. Due to the added stress and play on those single bolts, they broke loose and my car took off on its own. Safety cables are useless when the entire base plate comes off! Fortunately, I was not on the interstate and no one was hurt.
I was kind of "gun shy" about towing after that, but after the problem was explained to me, I feel confident towing with my Roadmaster base plate. I've even stopped crawling under the car to check the bolts!
by:
The etrailer installation video & paper instructions are both useful. It seems ford has minor design changes over the years. For a 2018 ford fiesta SE (no ecoBoost), remove the fascia (like in video) before removing the headlights. Headlights lift at front for the front clip and then push the light rearward for the rear clip. Fit on the passenger side was right on. Fit on driver side needed a little work. The driver side interior frame rail had an unused spot welded nut in the way. Drilled nut off with 1/2" bit from the outside. The passenger side interior frame rail has an unused spot welded stud head in the way at the side-brace edge.
I would buy again.

Everything was delivered despite the box being torn. Installation was completed in about 3 hours, however a spring wire to pull the bolts through the frame would have been useful. I would not recommend owner installation unless mechanical aptitude and a good selection of tools are available.

Everything arrived except 4 hy power diodes. I called and the lady was shipping them out tomorrow.

If you are not mechanically inclined do not attempt this yourself. If you think your mechanically inclined but don't do a lot of work on cars don't attempt this yourself. It is not hard for the mechanically inclined but it requires drilling on the frame and a lot of small parts off and back on. There is a video available, I highly suggest you watch it to determine if this is something you can do.

Installation was a bit trying. Ended up looking very clean and almost invisible.
Using the tow bar worked super easy and our motorhome hardly noticed the Mini Cooper back there.

Bolted right up. Installation should be done with bumper on, as you can't fit the ends through the louvers without some convincing. Works great so far. Was able to use a Stowmaster 5000 with it.

Thanks for the review and for sharing your installation experience Christian. Your tip about leaving the bumper on during install is really helpful, especially since fitting the ends through the louvers can take a little extra maneuvering. It’s also great to hear the setup works well with your Stowmaster 5000. The install looks great, and we appreciate you sharing the picture! Where did you go for the first trip?

Everything related to my Mini towing system is working great after a year of use.i do wish I had bought a cover for the tow bar though. Keeping it clean would be easier with the cover. Great products and service from etrailet

by:
The #118-3 is a perfect fit on my 1995 Geo Tracker. When you pull off the removable arms you would never know they are there. The Quality is very good easy to put on all you have to do is drill 4 holes the tube on the base plate fits into the tube on the frame of the tracker and with the 2 bolts it is a solid fit. I was worried about the plate nut getting it inside of the frame but it went in easy when you put it over the frame tube and use a thin piece of metal to slide it in place. I’m very happy with it. I probably could of got it on without taking my bumper off but with only 4 bolts holding my bumper on it made it easier

Awesome delivery speed, and a well made base plate for my 2007 Element. Installation was a breeze (thanks to my son’s heated shop) and I had to do no cutting to make this fit. I had a Stowmaster tow bar that came with my RV and etrailer was able to steer me to the correct missing parts to make this a really affordable installation. Now to get out of this snow!

We towed our 2004 Subaru Impreza WRX STI 3000 miles last year, this is an ideal setup, discreet when not in use, solid, and easy to get on/off. Very please with the support I received from Roadmaster as one of the bolt was missing, was sent super quickly.

Replaced same part that was damaged in a crash. I had used my original one for close to ten years without issue. Fast shipping from etrailer.

New system working fine. As with previous system it requires towed vehicle to be nearly perfectly aligned straight behind motorhome to disconnect without considerable tension.

The Base plate kit is well made and came with all the necessary hardware.Installation is relatively straight forward. I did have to enlarge two of the holes that didn't quite line up. But overall I'd recommend it.

Overall the installation was great, however the process of drilling 3 - 1/2" holes in that little bumper that has a Rockwell Hardness of about 60, seems to be a bit over the top.The instructions are spot on, delivery was great, the quality of product was accurate. I am a happy boy!

  • Parts Needed to Flat Tow a 2016 Ford Fiesta SE Behind an RV
    I will be happy to recommend the parts you will need to flat tow your 2016 Ford Fiesta behind your RV. The first item needed will be base plates. The base plates are what will mount to the Fiesta. They provide a safe attachment point for the tow bar. For these I recommend # RM-524438-4. The tow bar is what connects the RV to the Fiesta. There are a lot of options but not to worry because I will recommend one that will work best with your Fiesta. Non-binding tow bars are the way to go for...

  • Can a 2018 Ford Fiesta be Flat Towed with Low Mileage and What Parts are Needed to do so
    I took a look at the owner's manual for your 2018 Ford Fiesta and it does look like it can be flat towed but you need to have at least 1,000 miles on it (page 158) before doing so. Be sure to check your copy of the owner's manual to make sure it says the same thing and for any specific instructions for flat towing. The parts you need to flat tow your Ford Fiesta include a base plate kit, tow bar, safety cables, vehicle tow bar wiring, and a supplemental braking system. If you have an...

    I checked an online version of the owner's manual about flat towing for your 2017 Ford Fiesta and although I didn't find anything in there about a mileage requirement before flat towing, it is good practice to get at least 500 miles on a new vehicle before doing anything to or with it. This gives the vehicle a chance to break-in. The manual does say to put about 300 miles on new tires so I recommend going on a little road trip before flat towing your Fiesta.

You will need to consult the owners manual for other recreational towing procedures as well. For a base plate kit you would want the part # RM-524438-4 as a confirmed fit.

  • Is Ready Brute Tow Bar Compatible with Blue Ox or Roadmaster Base Plate Kit for a 2018 Ford Fiesta
    According to Ready Brute they have adapters for all Blue Ox, Demco, and Roadmaster base plate kits.

If you don't already have the correct adapter then part 857768004265 is for Blue Ox tow bars while parts 857768004289 and 857768004296 are for EZ4 and EZ5 Roadmaster base plates respectively.

    The reason that the StowMaster # RM-501 is not compatible with EZ5 base plate kits like part # RM-524438-5 for your 2018 Ford Fiesta is because the quick-disconnect is permanently attached to the tow bar. I spoke with my contact at Roadmaster who said that the only tow bars that are compatible with the EZ5 kits are the ones that mount inside the hitch receiver like the Falcon 2 # RM-520.
