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.


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.



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


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.

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

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

We ordered three separate items from etrailer, all were received as promised. We ordered the StowMaster 5000 by Roadmaster because we had one before but sold it with the vehicle when we purchased our new Jeep for towing behind our motorhome.. They are easily used by seniors and like that they are foldable for cruising. 406943

    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.
