On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs, as well.

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

2004 Jeep Wrangler

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.
However,,,
With our new vehicle, I am again going to purchase from this same company.
This fit our 2004 Jeep Wrangler X

2001 Jeep Wrangler

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.

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.

  • Parts Needed and Procedures for Flat Towing 2000 Jeep Wrangler
    Clevis rings are meant for recovering the vehicle when it is stuck, not for flat towing the vehicle. The safest way to flat tow the vehicle is by using a base plate kit that attaches to the frame of the vehicle. For the OEM double-tube bumper, I recommend the Roadmaster EZ4 # RM-521424-4 base plate kit. For the U-channel bumper or single-tube bumper, use # 1420-1. The Tow Ready tow bar you referenced would limit you 45 mph, so something like the Roadmaster Tracker, part # RM-020 would...

    You will need a base plate kit part # RM-521424-4 which is confirmed as a fit for your 2006 Jeep Wrangler. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. 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...

Roadmaster determined that the mounting location of the Roadmaster XL Base Plate Kit - Removable Arms # 1420-1 wasn't sufficient so they replaced it with the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-521424-4.

  • Can I Dolly Tow a 2000 Jeep TJ Wrangler
    From what I was able to find in the owner's manual of the 2000 Jeep TJ Wrangler, you're not supposed to tow the vehicle on a tow dolly that leaves only 2 wheels on the ground (I do believe it's because of the transfer case). You can either flat tow the vehicle or tow it on a trailer/dolly that keeps all 4 wheels off the ground. In order to flat tow your TJ you'll need base plates, a tow bar, tow bar wiring, safety cables, supplemental braking and in most cases, a high/low adapter. I've...
