Quick, Easy Hookup

This Roadmaster tow bar has a large hookup radius to ensure simple, secure hookup. What this means is that, even if your towed car is not perfectly aligned with your RV, you will still be able to make the necessary connections. To achieve this, the StowMaster has stainless steel, telescopic inner arms that adjust independently. In addition, 1 of these arms is able to pivot in and out, changing the spread. So, if your car is angled a bit behind your RV, you'll still be able to hook up by bringing the arms closer together and staggering the length so that 1 arm is longer than the other, allowing it to reach the more distant base plate.


The fact that the arms are extra-long also allows for a better turning radius. By putting more distance between your motorhome and your towed car, your entire setup will become easier to maneuver so that your towed car will track behind your motorhome without running the risk of hitting your RV during turns.


Autowlok

The Autowlok mechanism features a spring-loaded pin that locks the telescoping arms into place for towing. Once the tow bar is connected to both your RV and to the base plates on your towed vehicle, simply drive the RV forward until the tow bar arms fully extend, at which point they will automatically lock into place.


Once you've reached your destination and you're ready to unhook your vehicle, press the release button to disengage the spring-loaded pin. The arms will be able to telescope again, making it easier to disconnect. However, if you're on uneven terrain, or if your towed vehicle is not perfectly aligned behind your RV, chances are you'll experience tow bar binding. This is the result of tension that can build up in the telescoping arm, and it can make it difficult to disconnect your vehicle. Using a release tool (RM-066 - sold separately) will give you the leverage necessary to disconnect.


The internal self-lubricating nylon bushings help to absorb road shock and reduce wear and tear on the tow bar by eliminating friction between the inner and outer arms as they telescope in and out. Inside each arm, a built-in safety strap provides extra peace of mind by ensuring that the inner and outer arms won't separate in the event of a latch failure.


Quick-Disconnects

Quick-Disconnect

Standard on most Roadmaster tow bars, quick-disconnects make it a snap to attach the tow bar to your vehicle. Other methods require you to maneuver each tow bar arm individually and perfectly line up tabs on the arms with tabs on your base plates. Roadmaster's unique design lets you connect and disconnect the tow bar quickly and easily, all by yourself.


The quick-disconnect brackets come in separate pieces. The pieces that are positioned on the ends of each tow bar arm interlock with matching brackets that attach to your Roadmaster base plates. Sandwiched between the tow bar arms is a sturdy crossbar that essentially turns the arms into a single structure. This crossbar allows you to lower the tow bar as a single piece onto the quick-disconnect brackets on your towed car so that you don't have to connect each arm separately. When lowering the tow bar onto the brackets, make sure that the tab on each bracket lines up with the hole in the matching bracket. Then just insert the linch pins through the holes in the tabs on top to secure the brackets together. To remove the tow bar, simply remove the pins and lift the tow bar off of the brackets. These convenient brackets also make it simple to mount any number of Roadmaster accessories, from basic safety cables to the Guardian rock shield.


Superior Testing Ensures Excellent Quality

FEA test

This StowMaster tow bar has been subjected to rigorous physical and computerized testing to ensure that it meets Roadmaster's exceptionally high standards. Throughout the design process, Finite Elemental Analysis (FEA) is done. Each of these tests display a 3-dimensional image of the tow bar while it is put under thousands of pounds of pressure. Areas of stress in the tow bar can then be located and studied so that those areas can be strengthened. This process is repeated until any weak spots, particularly those found in load-bearing components, are completely removed. The result is a durable, strong, and safe product.


Simple Storage

FOLDED STOWMASTER

The StowMaster can easily be folded up and stored on the front of your towed vehicle when not in use. After disconnecting the tow bar from your RV, push the arms of the tow bar together so that they are side by side and fold them up towards the vehicle. There is a collar under the coupler that fits over a vertical post on the crossbar. This secures the tow bar in the stored position on the front of your car.


Guide to Flat Towing

Flat towing your vehicle is much more convenient than using a trailer or a tow dolly. These other options take up much more storage space, leaving you less room both at home and at the campsite. In addition, securing your vehicle to a trailer or tow dolly can be a hassle and more time consuming than hooking up with a tow bar.


There are 5 basic components needed when flat towing a vehicle: a tow bar, a base plate kit, a safety cable set, tow bar wiring, and a supplemental braking system.


FlatTowing Components

The tow bar links your towed car to your motorhome. It attaches to the custom-fit base plates that install on the frame of your towed car. Safety cables ensure that your towed car does not separate from your motorhome in the event that your tow bar becomes detached. Tow bar wiring allows your towed vehicle's signal lights to sync up with your motorhome's tail lights, which is required by law in most states. Finally, the supplemental braking system - also required in most states - brakes your towed car when the brakes in your motorhome are activated, preventing wear on the motorhome and decreasing braking distance for your entire setup.

Video Transcript for Roadmaster StowMaster Tow Bar Review

Today we're gonna be taking a look at the Roadmaster StowMaster Tow Bar RM-501. Here's what our tow bar's gonna look like once we have it installed and all hooked up. This is gonna serve as the attachment point between our motorhome and our towed vehicle. It's gonna be a coupler style tow bar, which means it's gonna hook directly up to a two inch ball. Just keep in mind, you do need a ball mount and you made need to find an appropriate rise or drop to match up so we can have a nice level towing setup.The arms on our tow bar are gonna have a self-aligning design to them, and what that means is they're gonna extend out and retract so it makes it a lot easier hooking up, even if we're not directly behind the motorhome. Once the arms are fully extended, they're gonna lock into a rigid towing position, and if you look on top here, we're gonna have this button.

That's gonna release the arms and let them telescope in and out again. And that's gonna make it a lot easier unhooking, so we can move the arms and uncouple as needed. The inner arms are gonna be made of stainless steel so they're gonna resist rust and corrosion and be a lot easier to slide in and out. On each arm, we're gonna have these nylon bushings. It's gonna make sure that the arms slide in and out easily and keeps out the dirt, grime, and debris.Both the arms are gonna attach to this slide bar here that's gonna allow the arms to come together, and then also I have this angle iron piece for added strength.

Both arms are gonna attach to this slide bar, so they can easily move into the stored position and then also I have this angle iron bracket for added strength. The arms are gonna measure out to 53.5 inches long in the extended position and that's gonna be measured from the center of the disconnect to the center of the ball. In the collapsed position, our arms are gonna be 43 inches long. Our tow bar is gonna be compatible with most Roadmaster base plates. However, it's not gonna be compatible with the MS, MX, or EZ5 base plates.Whenever we're not towing, unhooking is gonna be easy.

You can come to the coupler, unlatch it, and then we'll bring the arm up and make sure we unlock both of them, bring our couplers straight up. We're gonna slide the arm over and then right behind the coupler on the arm, there's gonna be this small rectangle. We'll rotate it over and put the post right inside that channel. Then we can secure it with the clip right here on that post. And then we have the option of storing it on the front of our towed vehicle just like this or we can remove it completely, and to remove it completely, we're gonna have two pins on the top.

We'll simply just pull the pin out on each side, then we can lift the entire tow bar off and store it somewhere safe. And putting the tow bar back on is gonna be just as easy. It's gonna slide right into the quick disconnect and then we can put our pins back in place.Our StowMaster is gonna have a weight capacity of 6000 pounds, but you always wanna double check your vehicle's weight as well as the hitch on your motorhome and the ball mount that you're gonna be using. Our StowMaster is a tried and true design. It's been used a lot, but compared to other tow bars with the coupler style, our StowMaster is gonna have those extendable arms. They're gonna make it a lot easier to unhook and hook up. Also, we're gonna have the option to store it on the front of our vehicle, as well as the quick disconnect, which makes it easy to install and remove.Daryll wrote in a year later saying he loves this tow bar. By himself, he can hook up to his motorhome and be ready to hit the road in 10 minutes. That'll finish up your look at the Roadmaster StowMaster Tow Bar, part number RM-501.

Have no problem with the hitch after we finally received the correct item. As you bring up the etrailer website, you are prompted with a MY VEHICLE before you start your order. We did this and ordered a base plate and tow bar around $900 total. After we received our order, we made an appointment to have our base plate installed. The shop told us our base plate was not for our car. We have a Ford Focus and received a plate for a Jeep Wrangler. We called etrailer as we had a trip planned and really needed this equipment. We were told by Tamara G that we ordered the Jeep Wrangler. Furious as we knew we did not because you would have to have went thru entering the year, make, and model in order to do this and there is a big difference between a Jeep and Ford Focus. We had to pay overnight shipping of $170 plus purchase a new base plate. I received the advice from an etrailer representative that said the next time we order for us to give them a call and make sure we ordered the correct item. We had this base plate installed, $280 and then we come home to hook up to our tow bar. It would not hook up. I called back to ask what etrailer would recommend now.....they said there was 2 base plates for our Focus and we was sent the wrong one (for the 2nd time). No reason to overnight it as we were leaving for our trip however, etrailer said they couldn't do that anyway. We just had to rent a car. Come home to find finally the correct part. I understand mistakes for we are all only human, but it is very frustrating to hear that you ordered a part for a vehicle you know you didn't. There is too many steps to go thru to order a part. We had to pay $31 to even send back the Wrangler base plate. We just ordered a 5th wheel with no trouble but this experience has been one for the books and very costly. 404389

This product is well made and well engineered. It performs the functions of allowing a reasonable amount of flexibility in coupler/ball alignment, locking into place, smooth vehicle towing and securing into the "stowed" position. Because of my bumper mounted winch, I needed to make some adaptations to the mounting system which the RM-501 accommodated very well. I am very pleased with this purchase. I will send a couple of installed pictures by seperate email. 488750

I bought the RM baseplate for my jeep because they may an adaptor for the Duncan tow bar. I got the Duncan on craigslist and it looked great. But I didn't know that I needed a DUNCAN quick release kit. It wasn't on it. The RM quick release only attaches the RM Duncan adaptor to the baseplate. So learn from my mistake don't buy a used Duncan unless you are sure you have all the parts. I out $200 for very nice looking hardly used but worthless Duncan tow bar plus the return shipping for the RM 038 and RM 021. The only solution to this was to buy the RM-501 tow bar which is what I should have done in the first place. It is very well made and easy to stow or remove. How much are they getting for scrap metal these days. 590594

Bought this from Etrailer with all the supporting hardware needed to flat tow my Durango. The quality is excellent (stainless steel, very strong), the install was pretty easy. Only issues I had were because of the are of my vehicle. Towing with it and hooking up is simple. It takes only a minute to go from stowed to hooked up. Etrailer.com was easy to deal with, helpful, and shipping was very fast. This is my second order with them, both have been flawless. Their pricing also proved to be the lowest. 343180

This is a premium quality item. Very well made from heavy materials. I'm still installing the baseplate so I haven't use the tow bar yet but as soon as I took it out of the box, there is no question it's a quality product. I'll review again after my first tow. There was a slight problem with my delivery in that I didn't receive the "vehicle side" hardware. I contacted etrailer.com and they are sending it out immediately. Really good customer service! 335320

  • Can a Roadmaster StowMaster Tow Bar Be Used On a 2020 Jeep Gladiator with Demco or Blue Ox Plates
    I do have an option for you but there are no adapters available for the Roadmaster StowMaster Tow Bar part # RM-501 because this is a tow vehicle mounted tow bar and said adapters will only work with motorhome mounted tow bars. Therefore, your only option will be to sell your Roadmaster StowMaster Tow Bar and then obtain one that is specially made for either the Demco Tabless Base Plate Kit part # DM9519336 for Overland, Sport, Sport S models and part # DM9519339 for Rubicon models or the...

  • Can the StowMaster be Used with an EZ5 Base Plate Kit on a 2018 Ford Fiesta
    The reason that the StowMaster # RM-501 is not compatible with EZ5 base plate kits like part # RM-524438-5 for your 2018 Ford Fiesta is because the quick-disconnect is permanently attached to the tow bar. I spoke with my contact at Roadmaster who said that the only tow bars that are compatible with the EZ5 kits are the ones that mount inside the hitch receiver like the Falcon 2 # RM-520. If you already have the StowMaster and you need a base plate kit for your Fiesta then you can...

  • Does the Roadmaster StowMaster # RM-501 Tow Bar Fit Specific Vehicles
    What you have in your picture is a very old StowMaster Tow Bar # RM-501 which is still attached to some base plates. I reached out to my contact at Roadmaster who said the serial number from the StowMaster indicates that it is rated for 5,000 lbs but there really isn't a way to determine what the base plate kit fits. If you let me know what vehicle the base plate kit was used on I can possibly give you some part numbers that you can compare to what you have but if you remove the StowMaster...

  • Parts Needed to Flat Tow a 2008 Toyota Corolla
    First you need a base plate kit like the Roadmaster XL part # 1165-1 which is a confirmed fit. This will work well with the StowMaster part # RM-501 which is an economic option that still is a great tow bar. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow...

  • Flat Towing Parts Needed for Towing a 2003 Suzuki Grand Vitara with a Roadmaster Stowmaster
    The RoadMaster StowMaster # RM-501 that you referenced is designed to attach to Roadmaster EZ, XL and Standard base plate kits. If you have one of those base plate kits on your 2003 Suzuki Grand Vitara then you would be good to go. If not you would need one, I would recommend the Roadmaster XL Base Plate kit part # 1011-3. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use the bulb and socket kit, # RM-155, and...

  • Should Steering Wheel be Unlocked on 2000 Toyota RAV4 When Flat Towing With StowMaster Tow Bar
    I took a look at the owner's manual for a 2000 Toyota RAV4, and when you are using the Roadmaster StowMaster Tow Bar # RM-501 to tow the vehicle, your steering wheel should be unlocked. The manual states on page 181, "The steering lock mechanism is not strong enough to hold the front wheels straight." I highly recommend contacting your local Toyota dealer for the exact procedure required to flat tow this vehicle as the owner's manual does not outright state what the procedure should be.

  • Parts Needed to Flat Tow a 2016 Ford F-150 with Roadmaster Stowmaster Tow Bar
    The Roadmaster Stowmaster tow bar part # RM-501 has a 6k weight capacity so it would work to tow your 2016 Ford F-150 as the weights I looked up for it are between 4 and 5.2k. For a base plate kit you would need to go with a new one since a kit from a Chevy truck would not fit. You would have to use the XL kit part # RM-524431-5 as that is what's compatible with your truck and the tow bar. If you were in need of safety cables you would then also need the part # RM-643 which are coiled. For...

  • Roadmaster Tow Bar Recommendation for a 2007 Jeep Wrangler
    Either of the tow bars you mentioned would work well for flat towing your 2007 Jeep Wrangler that appears to have a Roadmaster base plate kit installed on it. I would recommend the Stowmaster part # RM-501 as it has telescoping arms that will make attaching to your Jeep much easier than the Tracker part # RM-020.

  • Will RoadMaster StowMaster Tow Bar - 6,000 lbs, #RM-501, Fit on 1999 Jeep Wrangler with Flat Bumper
    The RoadMaster StowMaster Car-Mounted Tow Bar - 6,000 lbs, # RM-501, is a very good application on your 1999 Jeep Wrangler with the flat U-channel bumper being towed by a GMC 2500 HD. It does not include any safety cables or base plate brackets. You will need to purchase the Roadmaster XL Base Plate Kit, # 1420-1, which attaches to the tow vehicle frame. These brackets then allow the tow bar to attach to the tow vehicle. I also have safety cables available for the tow bar. You can...
