Features to know about

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

This setup keeps your front end looking clean when you’re not towing. The crossbar-style brackets sit far back on the frame, leaving the bumper uncluttered and the remaining hardware virtually invisible once the drawbars are removed. The partially hidden design also helps protect the brackets from scrapes and scuffs while maintaining that stock appearance that owners like to keep.

Hook Up Fast Every Time: Twist-Lock, Pull-Ring Release System

The drawbars on this kit use a simple twist-to-lock mechanism that clicks firmly into place. Built-in pull rings make it easy to unlock and remove the arms in seconds—no tools or pins to fumble with. It’s a straightforward setup that makes hooking up or disconnecting at the campsite quick and repeatable, even if you’re working solo.

Built Strong for the Long Haul: All-Steel, Computer-Cut Construction

Each bracket is computer-cut from all-steel plate for precise fitment and solid strength. The design bolts directly to the vehicle frame with no welding required, spreading towing forces evenly for dependable performance over long drives. A black powder coat finish adds durability and corrosion resistance so the setup stays solid through years of use.

Ready for a Complete Towing Setup: Compatible with Roadmaster Tow Bars

These base plates are designed to work with Roadmaster tow bars using the quick-disconnect crossbar (#910021-00, sold separately). Integrated mounting points let you attach an electrical connector plug or bracket when you’re wiring your lighting system. The kit includes clear instructions and mounting hardware so you can get everything installed cleanly and correctly at home.

I’ve been purchasing products from ETrailer since 2005 and all the products I’ve purchased have been a great value. The products mentioned above installed perfectly and with the direct assistance from ETrailer everything fit as suggested. I will always interact with ETrailer as needs present themselves.



by:

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!



by:

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.



by:

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.



by:

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.



by:

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.



by:

Came quickly and is very high quality. Great directions/video from road master makes the installation step by step easy to follow.
Skill level is probably at the intermediate level depending on experience.



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

Product arrived on time but was a lot harder to put on than shown on the video. I almost have it done but very hard for an old man. (80)



by:

works great



by:

everything I have purchased from you had worked as expected. thank you



by:

Received product in very quickly. My son & I installed it on 2015 Equinox only took about 2 & a half hour with no problems. Great directions & videos.



by:

Caught it on sale It was the price I was looking at elsewhere . Preferred E Trailer because of the great reputation and how to videos available .



by:

Loved the base plate and it works wonde rful.



by:

Quick shipping. Good packaging. Ready to install. This will allow us to tow our Equinox with no trouble



by:

The directions could be better as the pictures did not do a good job of showing how all the pieces go on the car so had to try to use the parts list to figure out how things go together. Also need better direction on what needs to be trimmed on bumper skin as had to drive 3-4 times to trim so bumper skin would fit.. Also the torque specs supplied did not provide for specific bolts used.



by:

This plate works great I was very satisfied. It was easy to install. When towing the car, you can't tell the car is behind you.
The plate was shipped fast, we will be ordering again from etrailer.com
Thank you for your prompt service.



by:

I have not completed installation of base plate yet. I found my experience with Brittany B (customer service) to be most enjoyable and informative. She confirmed all the parts ordered would be compatible and assured me if I had questions of any degree to contact her and she would get the answer. It's so nice to be able to speak with someone with knowledge and a since of humor. Thanks.



by:

Base plate is well constructed and fit my Chevy Equinox perfectly. Installation was straightforward and the instructions were very clear. Have been towing my Chevy for a year now with zero problems.



by:

etrailer is an excellent place to do business. I have placed several orders over the past few years and they deliver the goods. They are very prompt on filling the order and getting it out the door. The products I have bought have never been misrepresented in their adds and always have been complete no missing parts. Their prices are always very competitive. I can highly recommend etrailer as a good dependable place to purchase the stuff you need

Great



by:

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.



by:

Fit and finish is great, the illustration for what you trim on the bumper isn't great but otherwise pretty easy install (I ended up measuring between the mounts on the draw bar and just trimmed accordingly)

  • Will the Roadmaster EZ4 Base Plate Kit Work with a Towmatic II Tow Bar on a 2014 Equinox
    The Roadmaster Base Plate Kit, # RM-523160-4, requires the tow bar adapter, # RM-038, to work with the Towmatic II tow bar. The base plates on your Honda should have required this adapter as well, so if you already have the adapter, you could simply reuse it with your new base plates on the Chevy Equinox. The only other part you may be interested in is the Roadmaster Quick Disconnect Kit, # RM-201. This will make it easier to disconnect the tow bar from the adapter when you are not towing....

  • Base Plate and Flat Towing Equipment Recommendations for 2012 Chevy Equinox
    Since you have a Roadmaster tow bar, use the base plate kit # RM-523160-4 which is compatible with all their tow bars. The Falcon 2 tow bar, # RM-520 would be an excellent choice, this towbar also self centers and locks. Safety cables are sold separately as # RM-643. You'd need a few other items in order to flat tow the vehicle. For a wiring solution, I like the # RM-15247 diode kit. This allows a permanent installation and includes the wiring umbilical to connect the Equinox and the...

For wiring, you could use the Roadmaster Universal Hy-Power Diode Wiring Kit, part # RM-154.
