Features to know about

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

When you want a base plate setup that doesn’t ruin the look of your vehicle, this one fits the bill. The Roadmaster Crossbar-Style Base Plate Kit sits far back on the frame, leaving the brackets virtually invisible once the removable drawbars are out. The partially hidden design keeps the front grille clean and protects the attachment points from scrapes and scuffs when you’re not towing.

Quick Hookup Every Time: Twist-Lock Removable Arms

Getting ready to tow is quick and straightforward with the twist-lock system. Each arm slides into the bracket, clicks securely in place, and is released by pulling the built-in ring to twist and remove. The pull-ring release means no fighting with pins or clips after a long drive, and you can attach or remove both arms in seconds without tools.

Strong Where It Counts: All-Steel, Computer-Cut Construction

This kit uses computer-cut, all-steel parts for precise alignment and strength under load. The black powder coat finish resists corrosion for consistent performance through thousands of miles of towing. Because it bolts directly to the frame with no welding required, it spreads stress evenly across solid mounting points for a secure connection every trip.

Ready to Match Your Setup: Works with Roadmaster Tow Bars Using Quick-Disconnect Crossbar

If you already run a Roadmaster tow bar, this base plate integrates easily using the quick-disconnect crossbar (910021-00, sold separately). The kit includes instructions and all necessary mounting hardware for a smooth bolt-on install. Once it’s set up, the connection stays solid mile after mile so you can tow with confidence and keep your existing gear in play.

The brackets fit was good, quality was good. The installation instructions need to be updated for the 2020 Colorado. There were some unnecessary steps.



by:

Still working great, been using for about a year now.

I have ordered many products from etrailer and their customer service is 12 on a scale of 1 to 10. I ordered my products on the weekend and they were delivered on a Wed. I also later found cheaper prices on a few of the items and submitted the info for the 110% lower price guarantee and received the refund within a few hours. These folks are just plain great!

by:

We have been RVing since 1986. When we started towing a car we have used only Roadmaster Tow Bars and baseplates.



by:

I've installed the baseplate yet but a layout of the items in front of my truck appeared they will fit well. However, one of the ring handles for the spring loaded pins was bent from shipping.



by:

Bought the base plate for my new 2016 GMC Canyon. Installed it myself, went real well.

This was my 4th install of a RM base plate. Armed with several variants of written and video instructions we carefully started disassembling a new truck... Like the others base plates, everything fit. I have a 2018 GMC Canyon Denali 4x4 and the instructions were for a Chevy Colorado/Canyon/ZR2 and were off a bit. The GMC Denali install seems to be closer to the Chevy ZR2. In a few cases the trim fasteners and locations differed but all in all, reasonably similiar.

Some differences: I did not have to remove the air dam. The fascia was notched at the bottom.

Criticism: The width of vertical receiver plate introduced a gap between the 45 degree bumper core end brace and the truck frame. I might weld or bolt a shim to compensate.



by:

The bolt on tow brackets bolted up purfectly, followed the instructions that came with them & watched an online video, was a little time consuming but that varies by vehicle

Yup must have done it right,after a year of towing my chevy colorado around on Alaska roads,highways, dirt roads and potholes without any problems, it must be a good product



by:

I haven't installed these parts yet but past experience with etrailer has been exceptional. Great customer service and help when needed. I have viewed the videos associated with installation of these parts and am confident they will install with ease.

It would have been extremely difficult to install the base plate and associated parts without the aid of the installation video. It was a lifesaver. The procedure was detailed perfectly and the parts went into place effortlessly and fit like a glove!



by:

The units went on my Chevy truck great and they work well the only problem is I can't take off my tow bar unless I unbolt it from the base plates so I have to leave the unit on all the time. It would take 4 bolts to remove . Then I could unlock the base plates and turn them in order to remove them.

The base plates they are working fine I dont remove them they stay on all the time it has been 2 years now the tow bar that I use is bolted on so I would have to remove them to get the s out I should do this some time so they dont rust in place but real nice right now .



by:

The base plates were easy to install (great step by step installation instructions)- it is an easy configuration for towing the vehicle. The attaching plates are well hidden from view when not in towing configuration- It is so simple to install the attaching hardware to the base plates sand fool proof -you will know you have the attaching plates properly installed every you use them-

due to the current pandemic- we have not use the product as we intended-we have use it for several miles for towing our truck- so far it shows to hold its torque and stability-little bet of rust between base plates and engagement parts- i an happy with the hardware as it was recommended by your staff- Installation instructions were impeccable- reminded me of assembly instructions for critical hardware- i am happy with its performance so far



by:

Great shipping also fits really nice



by:

Simple to install. Easy to remove. Great product.



by:

Thank you. Thank you for helping me find the right parts.All parts went on well from start to finish. Shipping was all on time. Everything I get from etrailer. Is top notch.

  • Correct Base Plate to Tow 2015 GMC Canyon with Roadmaster StowMaster Tow Bar
    The base plate kit you need for your 2015 GMC Canyon so it's compatible with the Roadmaster StowMaster Tow Bar # RM-501 is the Roadmaster Crossbar-Style Base Plate Kit # RM-523182-4. This kit is directly compatible with the StowMaster but if you're missing the Quick Disconnect adapters or need to replace them you can find them as part # RM-222. For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system,...

    I did some check and it looks like only four-wheel drive versions of the 2018 GMC Canyon with a two-speed transfer case that has a Neutral and a 4-low setting can be towed four wheels down. For a base plate kit you'll then need the Roadmaster kit part # RM-523182-4 which is a confirmed fit and would work well. 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. The most popular compatible...

  • Why is Disconnecting Battery Necessary When Flat Towing a 2019 GMC Canyon Denali?
    It is necessary to disconnect the negative battery cable according to the manufacturer to protect your vehicle electronics. Some vehicles have some built in battery capacitors that keep the radio presets and some even do the seat memory settings. I'm not sure on your 2019 GMC Canyon Denali what will still be saved and what will be lost and need reset.

  • Can the Tow Hooks On a 2016 GMC Canyon 4x4 Be Used for Flat Towing
    The actual tow hooks on your 2016 GMC Canyon cannot be used for flat-towing as there would be no way to secure a tow bar to them. The same part of the frame that the tow hooks attach to will then be used for the base plates which attach to the tow bar but again there is not anything to directly attach a tow bar to the tow hooks. If you are looking for a more cost effective setup I recommend the Roadmaster Crossbar-Style Base Plate Kit part # RM-523182-4 with the Roadmaster Falcon 2 Tow...

    I'll start off by addressing the grille guard on your 2018 GMC Canyon; in most cases, grille guards are going to be mounted using the exact same points that are used for mounting base plates used for flat towing. For this reason you would need to first remove the grille guard in order to flat tow your truck. In order to re-use your crossbar style Roadmaster tow bar with your 2018 GMC Canyon you'll want to use the Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-523182-4,...

  • Difference Between Adaptive and Non-Adaptive Cruise Control
    Adaptive cruise control is something fairly new to the auto industry and is when your vehicle has a setting that basically matches the pace of the vehicle in front of you (speeds up and slows down as the vehicle in front of you does).

    The owner's manual of your 2016 GMC Canyon specifies that the two-wheel drive version of this vehicle cannot be flat-towed, and the only way to tow it at all would be to use a tow dolly and have it mounted by the rear wheels. However, the tow dolly's we carry state not to tow vehicles by their rear wheels. There is a possible solution for you though, requiring either the installation of a lube pump kit if your Canyon has an automatic transmission, or a drive shaft disconnect if it is...

  • Recommended Base Plates To Use with the Roadmaster Sterling All Terrain on 2016 Chevy Colorado Z71
    The adaptive cruise control (ACC) feature will adjust your speed while in the cruise control mode when an object traveling at a lower speed is detected in front of you. This was not a very popular option but if you call your dealer they will be able to tell you whether or not you have this. If you do then it will need to be removed in order to flat-tow the vehicle because the sensor locations interfere with where the base plate kits mount.
