2019 Chevrolet Equinox

The Jeep project went very well everything fit great and worked well. I really love Roadmaster products and quality and your company is the best place to purchase them. I sold the Jeep and replaced it with a new 2019 Chevy Equinox 2.0 L AWD and just purchased and installed the following items from you and installed them, RM-156-25 & RM-156-75 Battery Charge Line Kit, RM-146-7 Flex Coil Kit, RM-523193-4 EZ4 Plate Kit, RM-88333 Custom Seat Adapter, RM-751489 Stop Light Switch Kit and a RM-98160 Second Vehicle Brake Kit w/brakeaway. All these parts were in stock and arrived quickly and normal with you people, I really enjoy the o-line vidios as I do all my own installs. Thank you so much for your great service.
I will attach pictures of my install, you will see how I was able to fab a bracket and attach it to the existing mount on the base plate to mount the brakeaway switch and the air connection for the brake system.
I also fabricated a tail light bar as I didn't want to use mag-lights or splice into the factory lights and bulbs installed into the lights would not work as the factory brake lights will come on when the brake system is applyed and the turn siginals would not be visable.
Thanks for all you do, I would and do recommend you people to everyone who needs your products. Rob



Everything is working great, I installed a base plate kit, battery charging kit, stop light switch kit, second vehicle air brake kit w brakeaway and seat adapter on our 2019 Chevy Equinox and towed it about 14000 miles behind our motor home this past year and everything worked perfect not a problem with any product. These are great products, everything fit perfectly and performed perfectly. Thank you for great service and great products. Rob


The whole etrailer family has been great to deal with.


I am not quick to review a product, it's been over a year since I purchased and install this hitch.
After using this for a year, I found this to be excellent.
Absolutely no problems.
My wife and I installed it with no problems at all,,, easy to do.
The videos was detailed, letting feel comfortable in doing the job.

Sadly, selling the vehicle,, now we don't have it any longer.
With our new vehicle, I am again going to purchase from this same company.
This fit our 2004 Jeep Wrangler X


You guys and gals are still the best!


Install the crossbar in approximately four hours start to finish 2001 Jeep Wrangler

2001 JeepWrangler

well I finally put my tow bar base plate on. I'm 82 years old so I had my doubts as to weather I could do this so I checked out a location that could have one this job for me but they wanted a hundred and fifteen dollars an hour labor so I said to hell with that . I looked at the directions that you sent with the Base Plate and said to myself, I can do this. Well I did it. Your instructions were dead on and I had no problem at all, In fact I hade a little fun doing it. Thanks a lot It's going to be great.



Its going great


Arrived when stated


installed easily with no issues

2005 JeepWrangler

The base plate was as described, very good quality product. Install was easy, instructions were easy to follow. I had to call during install to clear up a question, they did not have the answer but called roadmaster while I waited on the phone and got me an answer. Very pleased with product, service and follow through.


I received expert advice on the selection of the base plate needed for my Jeep Wrangler. The product came in a timely fashion and was in great shape when I opened the box. The instructions that came with it gave step by step instructions and great pictures. I cannot think of anything that I was disappointed with.

1997 Jeep TJ

This base plate bolted up quickly to my 1997 Jeep TJ. Instructions were simple and truly made it easy. No problems after a year of installation, close to 4000 miles of towing.

2002 JeepWrangler

Perfect fit for my 2002 Jeep Wrangler. Makes hooking up to tow easy. There was some drilling that had to be done to the Jeep frame, but I already knew that before purchase. Etrailer was great and I will purchase here again.

  • Replacement Arms To Convert Crossbar Baseplate To Direct Connect On a 2000 Jeep Wrangler
    You will need a new set of baseplate arms for your 2000 Jeep Wrangler. The Roadmaster Replacement Arms # RM-ARMS includes a form found under the installation details(I have also linked this below) that will need to be filled out for the correct replacement arms. You will need to order arms for the Roadmaster Direct-Connect Base Plate Kit # RM-521424-5 which has the direct connect style arms versus your current crossbar style arms. These new arms will allow you to easily connect to your...

  • Recommended Parts For Flat-Towing 1998 Jeep Wrangler TJ
    The base plates you can install on your Jeep depend on the bumper style you have. If you have a U-channel bumper the base plates that will work are part # 1417-1. If you have an off-road bumper with the 1-inch D-Ring bumper mounts then the base plates for your Jeep are part # RM-035-1, and if you have the off-road bumper with 3/4-inch D-ring bumper mounts the base plates you can use are part # RM-035. If you have a double tube bumper I recommend the part # RM-521424-5 EZ5 base plates. For...

  • Blue Ox Base Plate Kit that Fits 2005 Jeep Wrangler
    Blue Ox makes a base plate kit that fits your 2005 Jeep Wrangler with a standard bumper with the part # BX1120 which will work great with your Blue Ox tow bar. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed...

  • How To Use a Tow Bar On a 2005 Jeep Wrangler with Metal Bumper and No Base Plates
    The Replacement Quick Disconnect Crossbar Assembly part # 910021-00 is designed for use with Roadmaster Crossbar-Style Base Plate Kits like part # RM-521424-4 which is a fit for your 2005 Jeep Wrangler so I cannot recommend that you attach this directly to what I presume is a metal bumper. If you have a motorhome mounted tow bar like the Roadmaster Falcon 2 Tow Bar part # RM-525 then the best option for you would be to weld a set of d-rings onto your front bumper which would then allow...

  • Parts Needed to Flat Tow 2006 Jeep Wrangler
    As long as the bumper on your 2006 Jeep Wrangler is rated for towing your vehicle you could use the # C19748 which comes with hardware to mount to it. With this kit you want to use the Curt tow bar # C19745. A frame mounted base plate kit would be a better option that we know will work though. For that the Roadmaster EZ4 kit part # RM-521424-4 would be a great option. And then for a tow bar the part # RM-520 plus the safety cables part # RM-643. For lighting you can use the diode kit,...

    First you will need to start with a base plate kit. For that the part # RM-521424-4 is a confirmed fit for your 1997 Jeep Wrangler and the bumper style in the picture you attached. 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 tow bar is the Falcon 2, # RM-520. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For...

  • Will the Roadmaster XL Base Plate Kit work with the Blue Ox Alpha Tow Bar
    Yes, the Roadmaster EZ4 base plate kit # RM-521424-4 is compatible with the Blue Ox tow bar # BX7380 (safety cables included) as long as you use Roadmaster base plate to Blue Ox tow bar adapter # RM-032 and Roadmaster tow bar quick disconnect kit # RM-201. The quick disconnect kit will make it much easier to attach and remove your tow bar. Also, it makes it so you can easily remove the base plate arms when not in use. I included a couple installation videos for you as well.

  • Does Roadmaster Crossbar-Style Base Plate Kit For 2001 Jeep Wrangler Work With Any Tow Bar
    So the answer is yes, your 2001 Jeep Wrangler will definitely be able to use the Roadmaster Crossbar-Style Base Plate Kit # RM-521424-4. The issue is simply the exact tow bar you have, which you didn't mention; the tow bar is compatible with all Roadmaster tow bars, and the majority of them have the ability to attach to crossbar-style base plates. The only thing you may need, if you have one that only uses the direct connect, like the Roadmaster Nighthawk # RM-676, is a crossbar assembly,...

  • Baseplate or Adapter Compatibility with Warn Bumper on 2013 Jeep Wrangler Rubicon
    If you don't have the Warn Elite then you would need to confirm with the manufacturer that the bumper is rated for flat towing versus just trusting forums. If it is rated by the manufacturer for flat towing then you can use the Adapter for Jeep D-Ring Bumper Mounts to Roadmaster Motor Home Mount Tow Bars - 1" Thick # RM-035-1 or # RM-035 for the 3/4 inch thick. If your Warn bumper is the Warn Elite, then you can use the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # 1439-3.

    I am happy to help you find the parts to flat tow your 2004 Jeep Wrangler. The Roadmaster Direct-Connect Base Plate Kit part # RM-521424-5 is a better option for a base plate compared to the Roadmaster # RM-521424-4 that you referenced because the Roadmaster Direct-Connect Base Plate Kit doesn't require you to leave the crossbar of your tow bar on the base plate to use the quick disconnect like the slightly older version.

    You can use a tow bar like the Tow Ready # 63180 to tow your 2004 Wrangler, but keep in mind, the tow bar is NOT rated for speeds above 45 mph, so I'd recommend a different setup. In order to run at highway speeds, I recommend using a tow bar like the Roadmaster Falcon 2 Tow Bar, part # RM-520 and base plate kit # RM-521424-4 which is compatible with OEM double tube bumpers. You will also need a set of safety cables like # RM-643. The Wrangler will also need to be wired for towing. There...

  • What Gear Should The Transmission Of A 2005 Jeep Wrangler Be Placed While Flat Towing
    There isn't a specific gear listed by Jeep to place your 2005 Jeep Wrangler Sport manual transmission in while flat towing it. Most Jeep owners prefer either 2nd or 3rd gear so it's really just up to your personal preference. The point of this is to keep the transmission components lubed while flat towing your vehicle.

  • Can a Jeep Wrangler be Flat Towed by the Front Bumper
    I have a solution for you, however, I would not recommend mounting a tow bar directly to a bumper on a Jeep, whether it is OEM or an aftermarket bumper. Jeep does not recommend towing the Wrangler with the OEM bumper because it was not designed to pull the weight of the vehicle. Also, mounting a tow bar to a bumper would require drilling. I spoke with my contact at Pavement Ends and she said drilling into this bumper would void the warranty and they do not recommend using it to tow the...
