To remove, simply twist the arms back and pull them out. 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.

This was my 4th install for a dingy (with 4 wheel flat towing) in the last 20 years. This install is for a 2018 Jeep Grand Cherokee, Overland. The New ROADmaster 90* twist & lock removable base plates are REALY Awesome! So much much easier & faster than installing & removing locking pins! One picture shows a Brush guard from ROADmaster no longer available.



by:

The Base Plates are performing as expected, unfortunately chipping paint has plagued these Base Plates. This chipping paint has occurred along both of the leading edge of where the tow bar mounts. This has not been caused from abuse/misuse, it started happening soon after began using. Should not have happened so soon.

2000 Jeep Grand Cherokee

I ordered this base plate to be installed on our 2020 Jeep Grand Cherokee Limited to allow it to be used with a Roadmaster Tow Bar that we purchased originally in early 2000 to tow our 2000 Jeep Grand Cherokee. Yes, 20 years later we are back into RVing and wanted to tow our 2020 Jeep behind our new Jayco Seneca Super-C motorhome. The only difference between 2000 and 2020 is the fact that we needed a brake activation system for our 2020 setup, something that wasn’t required in 2000. etrailer also sold us the Roadmaster Invisi Brake operating system which we had our local welding fabricator (also RV hitch installation expert) instal. Everything works perfectly and safely. Thank you etrailer!

Excellent! We have towed the Grand Cherokee with it for over 17,000 miles since installation, with no operational issues. From NW MT to west coast of WA, to Rockport, TX, to Duluth, MN and back in three separate trips.

This is an nice unit and the instruction included were spot on. It is very scary to rip the front end of your toad off to install a tow kit. But, nothing went wrong and the parts are great. Should be easy to remove and install when needed.

One improvement would be a better way to cut out the two grill parts for the tow extensions. I finally toss the originals and left open holes. It looks find. And bought new closures for the time that I decide to change the rig. If Road Master had produced a templant, I might have had something that I would have used. as it was, I screwed up the closure too much to use.

One year ago I purchased the equipment to tow my Jeep Grand Cherokee 4 flat behind my motorhome from etrailer. I received the items within 4 days, and was able to do the install myself thanks to the fantastic instructional videos provided by etrailer.
I have towed it from Iowa to Colorado, and several shorter trips. It is easy to
hook up/unhook and tows fantastic. I went with the Roadmaster Sterling tow bar as well as the roadmaster crossbar with removable arms. I would HIGHLY recommend this setup! I also put the roadmaster diode wiring set in the Jeep to use the tail lights. Works flawless! I have used etrailer for several items and have always been completely satisfied. Preston was super helpful in helping me choose the best equipment for my application! Can't go wrong with etrailer!



by:

Product installed easily hardest part was finding drill sharp enough to drill holes. Took about 4 hrs at a 75 year olds pace.
Looks nice and fit my existing tow bar with no problems. You may want to remind buyers they need a plastic pop rivet tool, not easy to find in local auto stores. I took advantage of my friend who owns a body shop, it took 2 minutes.

2012 Jeep Grand Cherokee

The base plate fit fitment is great. However, due to 2012 Jeep Grand Cherokee Summit manufacturing tolerances, there was a little shimming required on driver side radiator support bolt up on my installation (1/8" flat washer was used). Other then that, installation was a breeze.



by:

Installation was straight forward. Online video was a great addition to the included instructions. Brackets have worked well and are easy to set up for towing



by:

Thanks for the quick delivery. The base plates mounted exactly as per the instructions given. Real easy.
The next time I need new base plates for a different vehicle I'll make sure to contact you.

Thanks again.

  • Recommended Tow Bar and Other Parts to Flat Tow a 2014 Jeep Grand Cherokee Limited
    The tow bar I recommend is the Roadmaster Falcon 2 # RM-520. It's one of our most popular tow bars and you can't go wrong with it. It self aligns as you drive forward in your RV. It's also compatible with all Roadmaster base plate kits. The base plate kit I suggest is the Roadmaster EZ4 # RM-521440-4. It's designed specifically for your 2014 Jeep Grand Cherokee Limited. The arms are removable so they're not as noticeable as other kits can be. To power the Jeep's lights I suggest...

  • Recommended Base Plate Kit to Flat Tow a 2014 Jeep Grand Cherokee Overland
    Since you already have a Falcon tow bar I recommend going with Roadmaster base plates. You're correct that the old ones from your 2000 Jeep aren't going to fit. Both the EZ4 # RM-521440-4 and EZ5 # RM-521440-5 kits will work on your 2014 Jeep Grand Cherokee Overland. The biggest difference between the two is that the EZ5 doesn't need the Falcon's crossbar when you hook up. If you also need wiring for the Jeep's lights and a braking system I recommend the diode kit for the lights, part...

Since you're using a Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar - Motorhome Mount - 2" Hitch - 10K Item # RM-422 you can use either base plate with no adapters needed.

  • Differences Between EZ4 and EZ5 Base Plate Kits for 2011 Jeep Grand Cherokee Overland
    For your 2011 (or 2012) Jeep Grand Cherokee there are two base plate options. You have the EZ4 kit part # RM-521440-4 and the EZ5 part # RM-521440-5. There isn't a standard EZ kit that's a fit. The primary difference between the two designs is the way they attach to the tow bar. The EZ5 does not use the quick-connect crossbar which provides a cleaner look, but prevents you from using some accessories that mount to the crossbar such as a Rock Guard like the Roadmaster # RM-4000.

  • Recommended Base Plates for 2014 Jeep Grand Cherokee With Roadmaster StowMaster Tow Bar
    In order to connect your Roadmaster StowMaster Tow Bar # RM-581 to your 2014 Jeep Grand Cherokee I recommend using the Roadmaster Crossbar-Style Base Plate Kit - Removable Arms # RM-521440-4 because you won't need to use an adapter to connect to the tow bar. There may be a few other components you need to round out your flat towing setup, if this is new, so I've listed the parts I recommend using below.

Both Roadmaster EZ4 # RM-521440-4 and EZ5 # RM-521440-5 base plate kits that fit the Grand Cherokee will work with the Sterling tow bar. The same with the Cherokee except use EZ4 # RM-521447-4 or EZ5 # RM-521447-5. For either Jeep the Sterling tow bar safety cables will not work with the EZ5 kits. If you need...

The Falcon All Terrain part # RM-520 is a great option and is one of our most popular options. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground.

  • Will Miles Accumulate on Odometer of 2021 Jeep Gladiator When Flat Towed
    Miles are not added onto the odometer of the 2021 Jeep Gladiator when it's flat towed. The odometer is electronic, not mechanically driven off the transmission or differential so miles will not accumulate when the vehicle isn't running. In order to safely flat tow your Gladiator, you'll need base plates, a tow bar, safety cables, a taillight wiring harness, a supplemental braking system and possibly a high/low adapter if the installed height of the base plates has a +/- 3 inch difference...

    Yes a 2011 Dodge Durango can be flat-towed. My research shows the 3.6L V6 and 5.7L V8 Hemi Durango models are capable of being towed only if they have a 2-speed transfer case. You will need to check your owners manual to find out what type of transfer case you have. That said, you will need Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521440-5 (if you have adaptive cruise control).

Tow hooks, if present will need to be removed and left off the vehicle. This is an EZ4 style base plate which is compatible with the # RM-501 Stowmaster tow bar. In addition to the tow bar and...
