Roadmaster Base Plates - RM-521448-5

  • Roadmaster
  • Removable Drawbars
  • 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 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.

Fast shipping. Good communications with Amy. The install was easy and only took about 2 hours at most. Fortunately no drilling required on my 2017 Jeep Wrangler. etrailer's videos are great. The Roadmaster baseplate itself definitely seems to be of high quality material just like their tow bar, and best of all, Built in the USA! 936949

Honda

The baseplate was exactly what I needed since I already have a similar set up on my Honda CRV. This allows me to tow either vehicle behind my motorhome. I also used diode wiring kit RM-15267 and RM-156-25, the battery charge kit. The videos were extremely helpful. I watched the diode video kit numerous times and took notes, before doing that project. It would have been nice to have a shop and lift, but I had to do with a cold garage and driveway with some blankets to lay on. The battery charge kit wire was really not long enough, so I bought some 14 gauge wire and made a longer wire. My jeep battery is in the rear of the engine compartment on passenger side. Kit may be ok for front battery. I've tested everything except the charging wire and actually towed my Jeep for a few miles to make sure everything works as it should. I was a little disappointed when I saw what the markup on the base plate kit was, but I couldn't have done the installation without the videos, so I ended up saving the money to have it all done. I was pleased that the baseplate fit under my aftermarket EAG winch bumper, which was very reasonable. You can see that the installation is a clean one. Sorry the pics aren't in perfect order. 923864

Very satisfied with the base plate. The installation was very simple to do. The only problem I found was that during shipping one of the mounting studs for the wiring mount was bent and I had to straighten it out. 728761

2015 Jeep Wrangler

The Base plate kit fit my 2015 Wrangler very well. Drilling was a bit difficult (getting the holes lined up through the two frame plates was the most difficult), but once the bolts were in place, it fit and has worked perfectly for the last year. 727101

by:

Great product. looks like OEM, most people can not even detect its presence on the vehicle. There was an issue with having to drill a hole in the vehicle frame to get all the pieces lined up. This is not a job for someone with limited tools and auto tech experience. However, with a couple of friends who I imposed a "Friend Tax" to get it all done in good order . Overall a great product. 726936

This tow bar looks and feels substantial, it was pretty clear how to install it, I did have to drill the holes in the frame through one side and got one hole a little low. It took every trick in my construction book to get all the pieces in place and tightened, and not have to round out any holes. I like this bar and the removable pins. Buying from etrailer.com is easy and they have a strong tech support system. 705828

RM-521448-5 Review: I have a 2017 Jeep Wrangler and needed a way to hook it up to my 1991 Hawkins Diesel Pusher Motorhome. The etrailer staff was very helpful in helping me purchase the correct system. I like not having anything extend beyond the front bumper when not being towed. I use the RM-676 Nighthawk Tow Bar and the SM99243 SMI Air Force One Brake system for Air Brakes. 5 Stars! 635928

Ask the Experts about this Roadmaster Base Plates

  • What do I Need to Flat Tow a Jeep Wrangler JK with Factory Bumper
    To flat tow your Jeep Wrangler JK behind your motorhome, you will need a base plate kit, tow bar, safety cables, tail light wiring harness, and a supplemental braking system. Depending on the year of your Wrangler, you may also need a Brake-Lite Relay, # RM-88400, (2012, 2013, 2015-2018) or a Stoplight Switch, # RM-751452 (2007-2011, 2014). For your base plates and tow bar, I recommend using the Roadmaster Direct Connect Base Plate Kit, # RM-521448-5 for 2010-2018 or # 1429-3 for 2007-2009,...

  • How To Use a Tow Bar With a Poison Spyder/Smittybilt Front Bumper on a 2018 Jeep JK Wrangler
    I do have an option for you but the Roadmaster Direct-Connect Base Plate Kit part # RM-521448-5 is designed to be used with the factory front bumper on a 2018 Jeep JK Wrangler only. Unfortunately, Roadmaster does not test this base plate kit with aftermarket bumpers so there would be no way to confirm fit on the brands you mentioned (Poison Spyder/Smittybilt). I took a look at both the Smittybilt 76744 SRC Carbine Front Bumper and the Poison Spyder 17-59-010DBP1 Brawler Lite Front Bumper....

  • Flat Towing Equipment for 2017 Jeep Wrangler Unlimited Rubicon Recon
    To flat tow your 2017 Jeep Wrangler Unlimited Rubicon Recon, you'll need base plates, safety cables if you don't already have them, a taillight wiring solution, a supplemental braking system and possibly a high/low adapter. For base plates, you'll want to use the # 1444-3 which is compatible with the Rubicon Recon edition Wrangler with a stock bumper (the # RM-521448-5 you'd looked at isn't compatible with Recon models). For safety cables, use # RM-643. For wiring, use # RM-15267. For...

  • Flat Tow Jeep
    To flat tow your 2013 Jeep Wrangler behind your RV you will need a Base Plate Kit, Tow Bar, Safety Cables, Vehicle Tow Bar Wiring, a Supplemental Braking System, and possibly a High-Low Adapter. There are a couple of great brands that we carry for all of this equipment and a lot of it depends on what kind of setup you want when it comes to the brand. The 2 dominating brands for the Base Plate and Tow Bar are Blue Ox and Roadmaster. Although they are very similar in quality I prefer the...

  • Parts Needed to Flat Tow 2012 Jeep Wrangler Unlimited
    The SMI Air Force One part # SM99243 is a great choice for a supplemental braking system for your 2012 Jeep Wrangler Unlimited as it ties into the air brakes of your motorhome and applies the vehicle brakes in a proportionate amount. To see how this installs in a similar Wrangler I attached an install video for more info as well. This would not interfere with a winch install. Now if you wanted a braking system that's a simpler install we also have the Blue Ox Patriot part # BRK2019 which...

  • Flat Towing Base Plate Recommendation for 2000 Jeep Cherokee
    I'm assuming you're speaking of a Roadmaster Stowmaster 5000 tow bar, is that correct? If that's the case, you'll want to use the Roadmaster XL base plate, part # 1418-1 which fits Cherokee models that aren't equipped with a brush guard. In addition to the tow bar and the base plate, you'll also need safety cables like # RM-643, a taillight wiring harness like # RM-15267 and a portable supplemental braking system like the Roadmaster Even Brake # RM-9400. I've linked to an install...

  • How to Connect Roadmaster Base Plate Kit to Blue Ox Tow Bar
    To get replacement arms for a Roadmaster base plate kit you need the part # RM-ARMS and then to use it with a Blue Ox Ascent Tow Bar # BX4370 you'd need to use the adapter # BX88185 and you'd be set. Now the replacement arms for the Roadmaster base plates take some time as they are a custom order type deal. So if you are looking for a quick solution I would recommend going with a Blue Ox base plate kit like you mentioned # BX1126.

For a wiring kit to operate your Jeep's lights, I recommend the Roadmaster Diode 7-Wire to 4-Wire Flexo-Coil Wiring Kit # RM-15247 or to add a 6-way plug, the...

  • Air Dam Trimming Required to Install Base Plate Kit on a 2015 Jeep Wrangler
    You could try just trimming a section of the air dam out for the bracket to go through, but most likely you would find that it's lack of support would cause it to be rather flimsy and it would make tightening the bolts on the outside of the base plate kit difficult since the air dam could cover the access to them. I attached a link to the video for you to check out. You might try a different internet browser to get it to play on your computer/device.

It is built for your 2010 Jeep Wrangler and is compatibile with the Falcon 2 Tow Bar. The drawbars are also removable when you are not towing, which significantly reduces how much of the base plate kit is visible.

So if your 2018 Jeep Wrangler is the new JL model and you are using base plates EZ5 OR if it is a JK model and you are using # RM-521448-5 or # 1444-3 then you will be good to go without the crossbar.
