Roadmaster Accessories and Parts - RM-066

Tow bars with telescoping arms have locked and unlocked positions. When the bars extend, collars lock them in place. This release tool gives you the leverage necessary for releasing those collars so that you can easily disconnect your vehicle.


  • Helps you to release your vehicle from your motor-home-mounted tow bar
  • Is necessary only for non-all-terrain models
  • Made in the USA

The terrain at campsites is often less than ideal for disconnecting your towed vehicle. When the tow bar is at an angle or the car is not straight behind the RV, the tow bar can get in a bind, making the collars on its telescopic arms difficult to move. This release tool gives you enough leverage to manipulate those collars so you can get out of the bind and back on track.

Video Transcript for RoadMaster Release Tool for Motor Home Mounted Tow Bars Review

Today we're going to be taking a look at the Roadmaster release tools for motor home mounted tow bars. Part number is RM-066. As you can see, we've got a heavy duty design here on the release handle. Notch here is designed to fit right around our tow bar, then we've got our long handle, provides plenty of leverage for us to get our buttons released. Simply just slide that around your tow bar, push down on it and that's going to release the handle. This is going to come in handy for non ATR or non-all terrain style tow bars, to help get these released. There's always going to be more pressure on one than the other, unless your just dead lined up behind the RV with your car, and that doesn't happen to often.

It's going to give us a great solution, it's a nice, compact design so we can tuck this away in the back of the RV, it's not going to take up a lot of space. Just make life a little bit easier when we go to unhook our tow bar. That's going complete our look at the Roadmaster release tool for motor home mounted tow bars. Part number RM-066.

We bought a used RV. It had a an old Roadmaster 5250 tow bar. It needed the complete rebuild kit which was not in stock. The reps(I talked with several as I didn't know what to ask the first one) were all helpful and courteous. They found two separate kits which make up the complete kit so I got what I needed. They actually had Roadmaster drop ship one of the kits to me directly. I also needed the Quick Disconnect bar kit for the 5250. They helped with that also. They also had the 5250 release tool. They even had the cover for the old Falcon so when I recondition and paint the old bar it will look and stay as new. Great folks to deal with. They are close enough in price to the big "A" so the extra couple of bucks is worth it for the expert advice. Thanks! 386782

I recently put a RoadMaster Tow Hitch on my 2012 Toyota Corolla. When I went to take it off I was extremely frustrated in that I could not get the pins to release and had the feeling that I had just spent a whole lot of money for a whole lot of aggravation. After a web search I found this tool and etrailer. I used it this past weekend and it is a lifesaver when your tow vehicle is not on a perfectly flat spot. If you have a hitch like the one I purchased do yourself a favor and get this simple tool. You will not be sorry and it is well worth the price. etrailer is a GREAT business to work with. In additio, I received this in three days and payed the standard shipping fee. 188510

I just accidentally happened across this item while searching for tow bar accessories. It is hidden on most websites! After becoming aware of this (after 20 plus years of Roadmaster tow bars) I purchased it. What a concept. I don't know why I never thought of this myself! It is very helpful in releasing the pressure off the tow bar so that it can be unhooked. Especially when you are in a hurry. P.S. I reserched prices and "etrailer" (as usual) had the best deal. 425383

The release tool works perfectly, just as described. eTralier is the best company I have ever experienced. All my orders have shipped and been delivered much faster than I expected. They even beat Amazon. I had to return a base plate and wiring kit because I sold the car. There was no hassle and the refund showed up on my credit card within a few days. Great work etrailer! 329411

Fits perfectly on the older style RoadMaster BlackHawk tow bar that just has a button the extends up when the arms are locked out. It is easier to release button on tow bar arm when there is a little pressure on the arm. 74942


The Roadmaster release tool works great and I consider it a must have tool. I wish I had one when I first bought my BlackHawk tow bar.

Thanks to George J. @ for providing the most fantastic customer service. This Release Tool is invaluable for motorhome owners w/tow bars made by RoadMaster. Too bad RoadMaster no longer includes the tool w/towbar installation package. Thanks again George J. for following up & following thru on this back-ordered item. 233661

I have used one of these for many years. It is very helpful to use when it is necessary to release the tension on the tow bay assembly when it is necessary to stop the towed car on a decline or a rise in level. The use of this tool avoids the necessity of of using a hammer or other item to force the release button down. 39846

Fortunately you don't need to use this if you're careful about being on level ground, but sometimes you cannot, and this is a lifesaver. I've used the hammer before but this is much more effective and gives good leverage. Should be included with the tow bar. ETrailer is the best! 307601

Do you have a question about this Accessories and Part?

  • Can I Flat Tow a 2015 Honda Fit EX with Manual Transmission Behind A Motorhome
  • Yes, you can flat tow your 2015 Honda Fit EX with manual transmission behind a motorhome. There is slight differences between the Roadmaster EZ4 # RM-521569-4 and EZ5 # RM-521569-5. The main difference is the EZ4 is more universal and will have more fit options. Both will feature Twistlock series brackets that are virtually invisible. Since you will be flat towing your 2015 Honda Fit EX manual transmission, you will need the following items: a tow bar, safety cables, wiring and...

  • How to Get the Autowlok Buttons to Release on the RoadMaster Falcon 2 Tow Bar # RM-520
  • On the RoadMaster Falcon 2 Tow Bar, part # RM-520, usually one of the Autowlok buttons will require more pressure to release. This is the arm that has most of the tension between your motor home and your 2002 Jeep Liberty. If the Autowlok button(s) are hard to release, turn the towed vehicles (Jeep) steering wheel as far as it can go to the left or right, then as far as it can go in the other direction. Then, straighten out the steering wheel until the front wheels are in line with the...

  • Parts Needed for Flat Towing a 2005 Mini Cooper 5 Speed Behind a Sprinter Class C Diesel Motorhome

You have most of the parts correct, but there are some specific items you will need for your Mini. First, you need to wire the dinghy so that the combined brake and turn signals on the motor home will activate both the brake and turn signals on your Mini.

Next, you will need a tow bar. If you are towing with a motor home that has a 2 inch receiver, the RoadMaster Falcon 2 Tow Bar, item # RM-520, would be a great choice. You will not need the Roadmaster Tow Bar Quick Disconnect Kit, item # RM-201, that you selected with this tow bar, because the Falcon 2 comes...

  • Recommended Tow Bar and Base Plates to Tow a 2008 Chrysler PT Cruiser
  • Using the tow bar and base plate system should end up being less expensive than purchasing a tow dolly, but I can say that the tow dolly set up would require less pieces to get the PT Cruiser on the road behind your RV. If you are considering the tow dolly option, we do offer one tow dolly by Roadmaster, part # RM-2000-1. To equip your 2008 Chrysler PT Cruiser to be towed with a tow bar, you will first need to install base plate kit # 278-1. You can use receiver inserts, part # RM-200-5,...

  • Do Roadmaster EZ5 Base Plates Require the Use of the Crossbar
  • The EZ5 base plate kit part # 52923-5 that you referenced that you have installed on your 2016 Subaru Forester does not require you to use any crossbars so it would attach direction to the arms of your Falcon 2 part # RM-520. The release tool is part # RM-066. You'll want to have one of these around unless you always park on perfectly level ground.

  • Is the Falcon 2 Tow Bar RM-520 Rated to Tow a 2002 Chevy Tahoe 5.3L Vortec 4WD
  • I did some research on your vehicle, and it looks like the curb weight of your 2002 Chevrolet Tahoe model should be around 5050lbs. This would be under the 6000lb capacity for the Falcon 2 tow bar # RM-520, but you will also need to make sure that the tow vehicle and trailer hitch are both rated to handle this much weight. I would also recommend that you double check the actual weight of the vehicle, including whatever gear you choose to carry in it, to make sure that it will definitely...

  • Yes, the Falcon 2 tow bar # RM-520 is compatible with all Roadmaster base plates including # RM-523184-4 for your 2017 Chevy Equinox. I strongly recommend adding release tool # RM-066 because the Falcon 2 is not a non-binding tow bar and unless you are on perfectly level ground and straight it will be very difficult to release the tow bar arms. The other option is to go with a non-binding tow bar such as the Falcon All Terrain # RM-522. Once you go to a non-binding tow bar you won't...
