Roadmaster Tow Bar Base Plate - RM-521423-5

  • Roadmaster
  • Removable Draw Bars
  • Twist Lock Attachment

Designed for use with motor-home-mounted tow bars, the direct-connect brackets are virtually invisible, easy to mount and remove, and they eliminate the need for a quick-disconnect crossbar on your tow bar. Installs on your vehicle's frame.


Features:

  • Direct-connect brackets provide attachment points for your motor-home-mounted tow bar
  • Streamlined design creates supremely clean look
    • No obtrusive quick-disconnect crossbar
    • Hidden brackets sit even farther back than standard brackets
  • Drawbars attach and remove quickly and easily
    • Arms click to lock in place in brackets
    • Built-in pull rings let you unlock arms so you can twist and remove them
  • Computer-cut, all-steel construction provides exceptional strength
  • Black powder coat finish is durable and corrosion resistant
  • Simple installation - no welding required
    • Custom base plates ensure a perfect fit for your vehicle
  • Compatible with Roadmaster motor-home-mounted tow bars only
  • Instructions and mounting hardware included
  • Made in the USA
  • Limited Lifetime Warranty


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.

  • Parts Needed to Flat Tow 2005-2007 Jeep Liberty Behind RV
    In order to flat tow your Jeep Liberty behind an RV/motorhome, you need a base plate kit, a tow bar, safety cables, a lighting solution, a supplemental braking system, and likely a high-low adapter. Starting with the base plate kit, I recommend the Roadmaster EZ5 Base Plate Kit # RM-521423-5. These base plates are custom fit for your Jeep and feature a hidden bracket design for a clean look when you aren't towing. Its black powder coat finish is durable and will work do a nice job of...

  • Parts Needed For Flat Towing 2005 Jeep Liberty
    Hello Mark, thanks for reaching out. You can use the Roadmaster Direct-Connect Base Plate Kit # RM-521423-5 to connect your Falcon tow bar to your 2005 Jeep Liberty. Generally the tow bar and safety cables are the only components that can be re used. Depending on what lighting and braking system you were using, some components may be able to be reused, but I will need to know exactly what parts you have installed in order to say for sure. Here is a full list of the parts I recommend for...

  • Recommended Base Plate for a 2002 Jeep Liberty
    No, they're about the same. The most difficult part of installing these baseplates is having to remove all of the trim and essentially the entire front end of your Liberty. I have linked both installation instructions below. We've only got an install video for the Roadmaster and it has been linked as well. I recommend using the Roadmaster Direct-Connect Base Plate Kit item # RM-521423-5 for your 2002 Jeep Liberty. You already have the Roadmaster Falcon All-Terrain Tow Bar item # RM-522...

  • Parts Needed to Flat Tow a 2007 Jeep Liberty Behind an RV
    There are several differences between the EZ5 base plates # RM-521423-5 and the regular EZ base plates # 521433-1. The biggest difference is what each of them fits. EZ5 base plates # RM-521423-5 fit the 2002 to 2007 Jeep Liberty. EZ base plates # 521433-1 fit the 2008 to 2012 Jeep Liberty. Since you have a 2007 Liberty you would need to use either the EZ5 base plates # RM-521423-5 or the EZ4 base plates # RM-521423-4. The difference between these is the design of the removable arms.

  • Parts Needed to Flat Tow 2002-2004 Jeep Liberty
    We have everything you'll need to flat tow a 2002 through 2004 Jeep Liberty. But the first thing you need to determine is if you will buy one with a brush guard or without. If there isn't a brush guard you'd want the base plate kit part # RM-521423-5 with the Roadmaster Nighthawk part # RM-676. Or if you go with a brush guard you'd want the base plate kit part # 521426-1 with the Sterling tow bar part # RM-576. To protect either tow bar when not in use the cover part # RM-055-3 is recommended...

  • Parts Needed to Flat Tow a 2006 Jeep Liberty
    Unfortunately, the baseplates from your friend's CJ5 are likely not going to work. I can't say for certain since I don't know what they are but there are no base plates that we carry that will fit a CJ5 and your 2006 Jeep Liberty. We also do not have a list of installers around the country so there isn't a specific location I can refer you to. All the necessary parts to set your Jeep up to flat tow can be installed by a common mechanic so you may want to look around at shops that might...

  • How to Flat Tow 2005 Jeep Liberty 4WD
    I took a look at the online version of the owner's manual for your 2005 Jeep Liberty and for the 4WD model it lists the following procedure for shifting the transfer case to N (Neutral) so that it can be flat towed with all 4 wheels on the ground: 1. Depress brake pedal, 2. Shift transmission into N (Neutral). 3. Shift transfer case lever into N (Neutral). 4. Start engine. 5. Shift automatic transmission into D (Drive) or manual transmission into any forward gear. 6. Release brake...

  • Are there Base Plates for a Jeep Liberty that Do Not Require the Crossbar on the Falcon 2 Tow Bar
    If there are EZ5 base plates for your Jeep Liberty then all you would need to do is replace the base plates. Then you would not need to use the crossbar/quick disconnects with your Falcon 2 tow bar # RM-520. If your Liberty is a 2002 to 2007 you would need # RM-521423-5. If you have any other year outside of the 2002 to 2007 range then the whole set up would have to change. To determine the options I would need to know the year of your Jeep Liberty.

  • Roadmaster Base Plate Kit for 2004 Jeep Liberty to be Towed with Falcon Tow Bar
    For your 2004 Jeep Liberty the Roadmaster base plate kit I'd recommend the Direct Connect part # RM-521423-5 which is the easiest to connect to your Falcon tow bar and install. For lighting/safety cables, locks, and covers for the tow bar we have the Roadmaster Falcon All Terrain kit part # RM-9243-1 which comes with all of that as one part number. The diode kit that comes with this allows you to splice into the taillight wiring so that your RV controls the vehicle taillights and does...

  • Recommended Base Plates For 2003 Jeep Liberty Compatible With Roadmaster Eagle 5000 Tow Bar
    I spoke to my contact at Roadmaster and he informed me that your Roadmaster Eagle 5000 tow bar is compatible with base plates like the part # RM-521423-5 without any adapter needed. These baseplates are confirmed to fit your 2003 Jeep Liberty. For your application, I also recommend the following to complete your flat tow set-up: For safety cables, I recommend the RoadMaster 68" Single Hook, Coiled Safety Cables - 6,000 lbs # RM-643.

    Yes.

You may also need safety cables like the # RM-643 since the Falcon All Terrain does not come with them included. As a general rule of thumb, most manufacturer's base plates are compatible with most models of their own tow bars without an adapter required. There may also be some other...

    The base plates that are designed to fit your 2005 Liberty and work with your Stowmaster tow bar are part # RM-521423-4. These are the EZ4 base plates, and have removable arms so it gives your Jeep a nice clean look when they are removed.

    Yes, you would need a base plate to flat tow your 2005 Jeep Liberty. Your Jeep Liberty would also need to be a 4WD model and it cannot have the brush guard.

    First you will need the Roadmaster # RM-521423-5 Direct Connect Base Plate Kit so you can hitch to your Jeep. The hooks and brackets for tow hooks will have to be removed. Add to that a tow bar. I would recommend the Roadmaster # RM-522 All Terrain – Non Binding tow bar. A non-binding tow bar will let you easily disconnect your tow bar even if your coach and towed vehicle is not on level ground or at a difficult angle. The tow bar is the one point in flat towing that gets the most stress...
