Features to know about

Made for a Clean Front End: Hidden Design with Removable Arms

When you’re not towing, you don’t want hardware hanging off the front. This crossbar-style base plate kit keeps things clean with brackets that sit far back for a nearly invisible look. Once the removable drawbars are out, the only parts left are tucked inside the grille, protected from scrapes and scuffs. It keeps the front end looking stock and free of sharp edges that catch knees when walking by.

Hook Up Fast and Secure: Twist-Lock Removable Arms

Each arm slides into place, clicks to lock, and stays solid until you pull and twist to release it. Built-in pull rings make disconnecting easy without tools or pins to lose. That twist-lock setup turns hook-up into a simple two-step job, even if you’re doing it on your own at the campsite or driveway.

Built to Last Mile After Mile: All-Steel Construction

Computer-cut, all-steel brackets bolt directly to the frame, spreading towing loads evenly through heavy-duty welds. The black powder coat finish fights corrosion and road grime so the setup stays strong through long hauls and changing weather. It’s designed for durability that holds up after years of use and thousands of miles of towing.

Easy to Mount and Accessorize: Bolt-On Install with Smart Mounting Points

Everything bolts up—no welding required—and the kit comes with hardware and instructions for a straightforward install. Integrated mounting points let you add an electrical connector plug or bracket (sold separately) so your wiring stays tidy and protected. Once in place, it works seamlessly with Roadmaster tow bars that use a quick-disconnect crossbar (910021-00, sold separately).

PERFECT, EASY TO INSTALL WITH BASIC TOOLS, VIDEO ON HOW TOO WAS GREAT, AND I LOVED THE FREE SHIPPING. THANK YOU



by:

I ordered a base plate for my 09 Honda, installed trouble free, priced right, arrived on time............



by:

What a great company to do business with.I was going to have my Son do the install but with the help from the Pro’s at etrailers I did it my self with no problem. I take my Hat off to, Michael H, Nicole, and Amy who gave me advice and answered all my questions. Thanks again



by:

It looked like it was going to easy to install but the base plate holes didn't match up with the auto holes. I had to do a lot of enlarging of holes. Once it was installed I had a lot of trouble putting the car back together.



by:

Great product that fit the front of the 2008 Honda CRV perfectly. etrailer is the best to work with! Very client oriented! Highly recommend them as a vendor!



by:

Shipping and delivery was very fast. I had to enlarge a few of the holes on the brackets because they did not line up to the holes on the front of my 2007 CRV. That was the only thing that did not go smoothly. It was not a big deal, just took a little extra time to enlarge the holes with a Dremel tool. Other than that, great product.



by:

Took my time installing this and the instructions were very helpful.
I viewed the YouTube video, made notes, gained confidence and felt prepared.
Everything went well and the hardest part of the process was replacing the plastic fasteners in the fender well and the screws at the bottom of the fender.
The product appears to be good quality and fit better than expected.
Excellent communication and support.

Thank You



by:

The products I received was very good but the service I received from Etrailer was very good. I really appreciate your service. Frank Lemmons



by:

Quick and easy.
While others did not
have it in stock, etrailer did, plus free shipping, fast delivery and packaged securely.
Matt was very helpful and knowledgeable. He knew exactly what I needed.



by:

I have loved ordering from etrailer.com. products came with good videos and instructions. I felt secure in what I was ordering



by:

The instructions were good and the passenger side of the base plate fit perfectly, but the driver's side did not. Had to 'drill out' the holes on the top and the inside, because the pre drilled holes we off about 1/8 inch. This misfit resulted in a lot longer to complete the project.



by:

Base plate was complete with all needed parts, instructions were complete and easy to follow. The tow bar works great, and can hardly be seen , when not used. Would buy another if ever needed.



by:

Instructions were very good for the installation on my 2010 Honda CRV. Fit and finish were good. Product arrived as promised. Minimal tools were needed, but installation with the vehicle on the garage concrete floor was probably a little more tedious than that on a lift. I would say that you do need some mechanical talents to do this on your own.



by:

This backing plate for my CRV was exactly as described and the instructions were well laid out and clear. The job went smoothly without a hitch. Great product.



by:

thank you for the quick delivery of part#1559,1 base plate & part #13555 hitch receiver. I will try to send picture of my installation. thank you !



by:

I am truly impressed with the folks at etrailer. I felt like the personnel were completely committed to helping me make an informed and smart choice. The tutorials regarding the product were very helpful and informative. I have nothing but praises for etrailer and I will soon order the tow bar that will fit on my recently ordered tow bar base plate. I will HIGHLY recommend etrailer to family and friends.



by:

Excellent products, shipped as promised and arrived on time. I have installed all the products. Although it took me longer then a professional installer, I had little to no issues. The online installation videos for all the parts (which were attached to the online order status sheet) made it extremely easy to install. The videos were of a professional actually installing the equipment step by step. etrailer.com has a customer for life.



by:

Excellent product, fit perfectly. The instructions were "on the money." It was obvious that the towbar baseplate was custom made for this car. Everything slid right into place without having to "man handle" any of it.



by:

I couldn't be happier with my Roadmaster. The ease of hooking up and disconnecting, the sturdiness of the device. We are 3/4 timers in the RV and notice NO wear and tear. Fantastic! Worth every penny!



by:

Manufacturer sent the tow bar quick disconnects w/o the backing plates and bolting materials. After contacting etrailer customer service, they jumped on it and quickly got the missing pieces shipped. This was not etrailer's oversight but they got it resolved promptly. Thanks etrailer!!



by:

This hitch installed on our 2007 CRV easily and has worked great over the past year. Installation was completed by myself with no other hands. I did block up one side of the hitch with wood to the approximate height to aid in mounting the other side. Vehicle back end was raised via car ramps. All mounting holes lined up fine. The associated brake & tail light wiring kit made wiring easy as well.



by:

I purchased this hitch to go on my 2009 Honda crv, I found a video on youtube that showed how to mount it. I took my time but still had it mounted in 2 hours. I also like that I can remove the receiver very easily when I am at home or on the road. This is much better than having a dolly that you have to move around by hand. I would recommend this to anyone that wants to pull their toad all wheels down.

Still works great, I wish I had purchased it sooner.



by:

Installed this base plate on my 2007 CR-V today. Instructions were clear and very helpful. Had to drill out two holes through frame to install longer bolts. Only caution here is when trying to torque these two bolts , the hollow frame channel will begin to deform before torque spec is reached. Hope the Loctite holds!



by:

Having a video to show you how to install it was great. Went on with no problems and have been using it with no problem so far.



by:

Purchased a Stowmaster baseplate for my 2009 Honda CRV. The quality construction and welding on this base plate is superior! The engineering was excellent and the assembly fit perfectly! The installation instructions were very detailed and the color photos made the project easy and straight-forward!
Installation took about 2 hours but was not difficult.
Shipping was on time and quick!
Highly Recommend etrailer!!!!

See what our Experts say about this Roadmaster Tow Bar Base Plate

  • Parts Needed to Flat Tow a 2009 or 2010 Honda CR-V
    To flat tow your 2010 Honda CR-V you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and most likely a high-low adapter. I recommend going with the Roadmaster EZ4 Base Plate Kit # RM-521559-4. This will work great with the Roadmaster Falcon 2 Tow Bar # RM-520 and the RoadMaster 68" Single Hook, Coiled Safety Cables # RM-643 which are both rated for 6,000 lbs. For your vehicle tow bar wiring I highly recommend the Roadmaster Diode...

  • Connecting Roadmaster 1559-1 Base Plates with Missing Weldments to Blue Ox Tow Bar
    I reached out to my contact at Roadmaster and he said that the Replacement Driver Side Arm C001477 will not fit your existing Roadmaster 1559-1 base plates. He said that the weldments for your particular base plate kit are no longer available so your only real option at this point is to replace the entire kit. If you were to go with another Roadmaster Base Plate Kit like part # RM-521559-4, which is confirmed to fit your 2007 Honda CR-V, you would still need to add the Adapter # RM-032...

  • Replacement Tow Bar to Flat Tow a 2007 Honda CR-V with Roadmaster Base Plates
    Wow, that's pretty crazy. I'd consider myself pretty lucky if I had a near-miss from a falling Redwood and only had damage to the tow bar. There's definitely a question there. You're looking for an easier to use tow bar to replace the Stowmaster, part # RM-501, that was damaged. You also need to make sure it fits the base plate kit already on your 2007 Honda CR-V. The base plates you have are likely the EZ4 kit, part # RM-521559-4, that works with the Stowmaster. For a hitch mount...

  • Parts Needed to Flat Tow a 1999 or 2011 Honda CR-V Behind a Motor Home
    I am a little confused because you entered 2011 Honda CR-V for vehicle information and typed it in the title field but the question is on a 1999 Honda CR-V. If you have a 1999 then base plates # RM-521559-4 will not fit. You need # 1528-3. For either set of base plates they are compatible with the Stowmaster tow bar you have. I have included a link showing installation of the 1528-3 base plates for you to view. You will also need safety cables if you do not already have some. I like cables...

  • Can a 2008 Honda CR-V be flat Towed Behind and RV Using a Tow Ready/Reese Tow Bar 63180
    I would actually advise against using Tow Ready tow bar # 63180 for a couple of reasons. First, this tow bar is rated for a maximum of 45 miles per hour which is fine for short hops around town but useless for highway use. And second there are base plates required, # 40602, but they are going to require major modifications to the bumper and need to be reinforced so professional installation is recommended. The other option is to use custom base plates # RM-521559-4 with an adapter # RM-025...

  • Correct Base Plates for 2007 Honda CR-V With StowMaster Tow Bar
    I believe you are speaking of the Roadmaster StowMaster Tow Bar # RM-501, as the Stowaway # RM-4000-40 is a storage system which slides over a tow bar. In order to use your StowMaster you would need the Roadmaster EZ4 Base Plate Kit # RM-521559-4, which is confirmed to work with that tow bar and will allow you to use the quick disconnect system. That system features brackets on the StowMaster and EZ4 plates which line up and are held in place with the pins that you referenced.

  • Comparing the Roadmaster Direct-Connect and Crossbar-Style Base Plates for a 2010 Honda CR-V
    The Roadmaster Direct-Connect Base Plate Kit part # RM-521559-5 and Roadmaster Crossbar-Style Base Plate Kit part # RM-521559-4 are both fits for a 2010 Honda CR-V. The main difference between the two is that the Direct-Connect style connects directly to a tow bar like the Roadmaster Nighthawk part # RM-676. The Crossbar-Style connect to a crossbar and then to a tow bar like the Roadmaster BlackHawk 2 part # RM-422. I prefer the Direct-Connect as there is less to connect each time and...

    From my research of the owner's manual for your 2007 Honda CR-V it is stated that the vehicle must be towed with all 4 wheels on the ground to avoid damage to the 4WD transmission. I do have other options for towing your CR-V. I recommend flat-towing your Honda behind your motorhome. For flat-towing there are 5 items that are needed.
