    • Improved aesthetics compared with standard brackets
  • Computer-cut, all-steel construction provides exceptional strength
  • Black powder coat finish is durable and corrosion resistant

Very rugged kit with excellent instructions. A DIYer with medium mechanical skills can install. Involved removing the front bumper which was not difficult. Value for the price is very good. As always, etrailer support was also very good.

Rock solid

Thank you All at etrailer.
Once again
you All have out done yourselves, which is big job. Due to the fact you always do a great job.
Well there was one time, when an item was shipped from the manf. But even then you sent a reimbursement for a portion of the labor cost it took to make the hitch fit a Classic 1981 El Camino.
Even in this difficult time of covid, your still doing your best.

Just fine

Our items were promptly shipped and received with no problem, other than the UPS gal struggled with the weight of the base plate. Thanks!


Adam was awesome to talk with on the phone , went through step by step on what I needed and what I didn't for what I was wanting to do.

2015 Chevrolet Colorado

Easy to install and has worked great since installing. Would recommend to anyone with a Colorado or any other vehicle.


I ordered a Falcon II tow bar, Base plate for a GMC Canyon, Demco Stay-n-play braking system and safety cables. worked exactly as it should, directions were easy to follow. All hardware was included. This system allowed us to tow our Canyon 10K miles around the country. super easy to use and I was able to connect and disconnect in less than 5 min. I liked the system enough that I bought the same setup for our new vehicle.


Awesome service. Installing it this wee kend.....

Review from a similar XL in Base Plates

Item arrived earlier than predicted after viewing a very complete tracking system. The information was very clear and precise. Good job! I am 75 years of age and installed the baseplate myself. Only a couple of minor issues. One pin would not insert. Welding blob in the way. Filed it smooth and problem solved. The video was excellent but was a bit different in that it showed a different method o rear bolt installation, however the instructions on paper showed the correct way. Reinstalling the front clip had presented some difficulty. I suggest really watching the inner fender position relative to the front clip before removal. All said all went well. The finished look is great, (see pictures). Great product!

Worked well, towed truck all summer.

Review from a similar XL in Base Plates

Base plate 1910 install on 1999 Landrover disco 2

the base plate arrived fast (as does everything I have ordered from etrailer). It was a bit bent on arrival but Becky sorted me out and offered to replace it but it was easy to bend back (with a 3lb hammer).

The included instructions were great for removing the bumper but nor much else. Possibly because my Landy is a 1999 disco 2 and the pictures were of a 2002.

I have included some pictures of stuff I wish I had known. Firstly I had to loose the recovery loop on the driver side as the base plate would not fit over it. The chassis frame has steel tubes inside the bolt holes so the amount of drilling is minimal (I ordered a drill bit that they suggested but in all honesty could have opened up the holes with a file easily).

You need to oval out the aluminum crush cans before you replce them or the new bolts will not go through. The center mount bolt just needs the plastic mount for the center screw on the scoop cut out and there is a bog square hole on the top of the member (thats why you need to big square piece of steel on the top of the center bolt)

Mine was obscured by the torsion bar so I ended up dropping it to drill out the hole and get the bolt in straight.

It was easy to bolt up to the frame once everything was prepped and do yourself a favour and buy loctite red for the bolts - you don't want to be going in there again.

The bumper template was a good start but I had to reshape mine a lot particularly as the hole on the baseplate ended up halfway through the bumper and I had to do a lot of enlargement at the bottom to attach the safety wires.

The photos should make more sense of some of my description


Review from a similar XL in Base Plates

Arrived a day early and well packaged. Included everything needed for a clean and easy install, down to electrical connectors and zip ties. The included instructions were very clear for a variety of wiring conditions. Umbilical cord looks to be of high quality.

One year down the road and still not a single issue. 5 minute attachdetach let’s me easily separate the Tracker and drive through the RV park with no toad following.

Fairly easy to install base plate. Left
all bolts / nuts loose, slid tow bar in to align while tightening up. Ready for motorhome.

Absolutely no issues to date. Great product

Review from a similar XL in Base Plates

These components are heavy duty. I have pulled my Jeep many thousands of miles over many road conditions. I am currently planning a coast to coast rv trip and will be towing my Jeep.

We pulled our Jeep for three months though 26 states from California.
Raymond - 02/23/2022
Product arrived quickly packaged well and order was complete. Components are strong and durable. Towed Jeep over 11,000 miles since purchase without any problems.

Review from a similar XL in Base Plates

Super nice people at etrailer. I wasn’t sure exactly what I needed and they helped me pick out the best hitch for me.


Review from a similar XL in Base Plates

Aligment with the Roadmaster Crosbar is slightly off, requiring a bit of muscle and manipulation to attach it. However, once assembled on the car it is rock solid and near bullet proof. Tow anywhere!

This video is on a 2010 but it will give you the information you are after in locating the bracket appropriately.

  • Moving Base Plate Kit from One Vehicle to Another
    A vehicle base plate kit is designed and engineered to fit a specific vehicle. I am sorry to say that the base plate kit from your 2000 Wrangler will not fit on your Colorado. As long as your Colorado is not an Extreme or Z71 model, you can use the # 3122-1 base plate kit. I have linked you to several of our flat towing FAQ articles that you might find helpful.

    The Roadmaster # 3122-1 XL Style Base Plate you mentioned is compatible with any of the Roadmaster Tow Bars, or to use a Blue Ox tow bar, a # RM-032 adapter would be needed. The Base Plate is compatible with a 2004-2009 GMC Canyon/Chevy Colorado, as long as it doesn't have the Xtreme package, as well as the 2010-2012 Canyon/Colorodo, with the exclusion of Xtreme and Z71 models. You'd also need a tow bar, safety cables, a wiring harness so the taillights of the truck operate with the turn...

    The Roadmaster Sterling All Terrain Tow Bar, part # RM-576, will include the safety cables, electrical wiring, and the quick disconnects.

For a base plate kit you'd then want the part # 3122-1 which is a confirmed fit. 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.

    According to Roadmaster, no fuses will need removal. Your truck is capable of being easily flat towed ONLY if it's a 4x4 model. Otherwise, modifications like a driveshaft disconnect will be required for a 2WD model. You can find more information about a disconnect via a Google search.

    The battery disconnect requirement does not intertwine with any charge line kits and it's main purpose is to protect your vehicle's components.
