Note: Roadmaster direct-connect base plates will only work with Roadmaster tow bars that slide into a trailer hitch, such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2. These base plates will not work with tow bars that require a hitch ball.

The drawbars, or front arms, on this base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. To remove each arm, simply tug the built-in pull pin to disengage the lock, twist the arm back and pull it out of the bracket. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs as well.

2020 Ram ProMaster 3500

Installing on 2020 Jeep Trailhawk :

Pic #0557 : Roadmaster Base Plate Kit , Demco Supplemental Braking System , Diode Wiring Kit , Demco Battery Charge Wire Kit

Pic # 0548 ,0551 , 0559 Had to adjust the bracket plate to line up with the upper bolt holes

Pic #6028 finished install , mounted the operating unit to the top fuse box cover using automotive Velcro . Air cylinder , controller and LED light installed . Aside from the base plate bracket not lining up with the upper bolt holes I would give it 4 stars . My son in law is a master at solving mechanical issues .


The install was straight forward just as in the video for my 2018 Jeep Cherokee. Do watch the videos even if you are mechanically minded, they help a lot. The written instructions need a little refining. At times the illustrations have arrows that point to the wrong item. Overall a very solid product. I am presently 1/3 of the way on a 3000 mile trip and all is working as expected.



Although we sold the Jeep Cherokee, the tow gear and Invisabrake system that we installed worked wonderfully without a flaw up until we sold it. We are purchasing again for our newest TOAD.


We have towed our Jeep almost 2,000 miles since installing the recommended parts from etrailer and it has worked perfectly on every connect and disconnect along the way. Tows beautifully, even at 70 mph.

Excellent customer service and helpful videos from these folks. Would recommend to anyone needing help with parts and guidance in towing their toad to give them a call.

Our system is still working perfectly a year later. Our Jeep is a 2018 Cherokee Trailhawk and while we’ve seen some RV forums talk about “death wobble”, we have never experienced this using these Roadmaster products towbar & baseplate. We tow the Jeep with our 39’ Class A gasser and hardly know its back there. Even on sharp corners the Jeep follows perfectly and no binding. Connecting or disconnecting takes maybe 5 – 7 minutes. Then check all of our lights, make sure the Jeep is in neutral wbrakes off and we’re on our way. The braking system that we installed purchased from etrailer is the “Stay-n-Play Duo”. I would recommend that to anyone looking for easy operation. The installation time was a bit lengthy and involved but once completed makes all of your towing trips much easier. Just the flip of a switch and the braking system is ready for towing. No portable unit to lug around and adjust each time you tow your vehicle. The etrailer folks made the perfect recommendations for our needs and everything has worked GREAT!

2016 Jeep Cherokee

Just got done installing them by myself. They are super easy to install. The only thing hard about it was taking off and putting back on the stuff on my car. ?? haven't towed with it yet!


Great product and fitment. I have yet to tow my 14 Cherokee Trailhawk yet but the installation was extremely straight forward and between the detailed written directions and the video, installation was a cinch. Installed base plate, light diode, battery charger, and breakaway in 6 hours. Baseplate required very minimal facia trimming. Bought a dremel for cheap on Craigslist with a metal cutoff bit and trimming tool. Perfect tool for the job. etrailer customer service and shipping is top notch

2017 Jeep Cherokee

This kit was a perfect fit and the instructions were superb. Removal and replacement of the entire fascia on a vehicle is intimidating, but the step by step process was amazing. I am very satisfied with the results. One tip - The instructions reference wiring, which is helpful. I mounted the fascia without attaching it so I could properly locate and cut out for the umbilical connector and breakaway switch.

2017 Jeep Cherokee

Absolutely great product. Installed as instructed without a problem primarily because of the video provided by etrailer on the website. Could not have done it as quickly and smoothly without that video. Roadmaster baseplate is very sturdy and does NOT require cutting the steel bumper mount flanged as the blue ox version does for my Jeep. Yet I can still use a blue ox tow bar with an inexpensive adapter on the ends. Very sturdy, quality setup.


Received product in timely matter/ product is of excellent quality. Did the install my self with the help of your great video. I have purchased many products from Etrailer Been very saddisfied. Now can tow behind motor home.


The product fit just as I said it would. After watching the video it took me 4 1/2 to 5 hours to completely install the base plate kit. Looks great and would recommend this product to anyone looking for one of the best tow system on the market today. Roadmaster, Inc. towing and suspension solutions

2017 Jeep Cherokee

These base plate adapters work fantastic. We tow our 2017 Jeep Cherokee trailhawk behind our class C RV without issue at all.
Thanks a lot

2017 Jeep Cherokee

eTrailer is.,in my humble opinion, the best place to source and buy all things tow related. Their knowledge base is impressive and they take the time to get the CORRECT information and products in your hands quickly. They also include product installation instructions and videos which are invaluable whether you self install or have a mechanic install the product. I have used them in almost every aspect to get my 2017 Jeep Cherokee Trailhawk prepared for dingy/toad towing. Thanks Guys!!

2015 Jeep Cherokee

Base plate installed on 2015 Cherokee trailhawk. Instructions were just fine. Pics were great. However lets get a warning in there on step 6, when drilling through the rivet on the drivers side, be careful because the winshield washer fluid reservoir is just on the other side. I drilled right into it and dropped a full tank on my dad's garage floor, not cool!
Very well built, heavy duty. First tow this weekend!

2015 Jeep Cherokee

The product was exactly as described and shipment was expedient. etrailer will always be my first choice for my trailing needs.
