When towing your vehicle with a tow bar, all 4 wheels are in contact with the ground. Certain vehicles - namely, those with front-wheel-drive automatic transmissions - require either a transmission lube pump system or a driveshaft disconnect when being flat towed. Using a tow dolly eliminates the need for those by lifting your vehicle's front wheels off the road. In addition, using a dolly eliminates the need for base plates that clutter the front of your towed car, difficult-to-install wiring, and a potentially expensive supplemental braking system. Also, if you want to tow multiple vehicles, this dolly is a great alternative to traditional flat towing because you don't have to purchase and install brackets and wiring for all of your cars.


Superior Design

Electric Brakes

The built-in electric brakes make it safe and easy to stop your vehicle while you're towing. This meets towing requirements, and also helps prevent the extra wear and tear on your RV's brakes that would otherwise occur because of the added towing weight. An electric brake controller (sold separately) must be purchased and mounted inside your RV to complete the installation. In addition, you will need a 6-way or 7-way trailer connector on the dolly so that it can receive the braking signal from your RV.


Universal Compatibility

The sliding ramps offer a 47" range of adjustment to ensure a precise fit for almost any vehicle you decide to tow. Also, the included wheel nets adjust to fit tires that are up to 30" outer diameter x 11" wide.

This Roadmaster tow dolly was manufactured extremely well. The welds and metal grade are traditional made in America high-quality. Putting it together at home will take two people and the right tools-plan for the day accordingly. I used heat shrink wrap, high quality electrical tape and zip ties to control the wiring better. Follow the assembly directions carefully.This is one heavy product delivery. I towed our Ford Focus and it tows beautifully. Backing up can be challenging. When loading your vehicle you may have to get your front tires very close to the tip of the rack to make the fulcrum effect work. Once again this is a great product and worth the extra $.



by:

Added a spare tire carrier and wheel jack (also available from eTrailer). With attention to all fasteners and tire pressure, tow dolly performed well. First trip out of the box was 4000 miles rt to Yellowstone NP, no problems.



by:

Dolly seems fine. Still putting it together. But there was never any any type of tracking information provided. Just a note it was received on the 1st. It said it was shipped on the 5th and then nothing until we got a call for delivery on the 14th. I generally get some sort of tracking information which I much prefer.



by:

Other than a few missing parts(washers) went together pretty easily. Seems sturdy. When for a break down run; no issues; tracked fine.



by:

It is a great trailer, very high quality. It is the first time I every used a car dolly, I was amazed how easy and quick you can load and unload your car. Trailer very stable when pulling.

  • Recommended Brake Controller for Roadmaster Tow Dolly with Electric Brakes
    Hi Jerry; you don't need a specific brake controller for the Roadmaster Tow Dolly # RM-2050-1. Any electric brake controller will work. My personal recommendation would be the Redarc Tow-Pro Liberty Brake Controller # RED24FR. This brake controller is simple and reliable. The main unit installs behind the dash with only the control knob visible so it doesn't take up space in the cab. You will also need the # RED69FR for installation. There may be a custom wiring harness for your vehicle,...

  • Solution for Towing 2017 Toyota Prius Behind Motorhome
    You are correct, the 2017 Toyota Prius that you have can only be towed on a dolly behind a motorhome. Good news is it won't put miles on the vehicle since the drive wheels will be on the dolly. I like dolly setups over tow bar setups for a number of reasons. The install time is considerably less, you can easily transfer the towing setup to a different vehicle unlike base plate kits that are vehicle specific, and you don't put miles on the vehicle. The price isn't that different either when...

  • Towing 2016 Mini Cooper JCW Hatchback Behind Motorhome
    We've had this question before and the answer is that we don't have a base plate that will fit your JCW model 2016 Mini Cooper due to the intercooler location but we do have a way to tow the vehicle with a tow dolly like the Demco Kar Kaddy SS Tow Dolly with Disc Brakes part # DM9713045. The Kar Kaddy SS is the perfect all in one tow dolly. It has disc brakes for maximum stopping power/reliability, a folding tongue for easy storage, and a wheeled jack to maneuver the dolly around while...

  • Best Way for Towing a 2019 Mini Cooper Convertible behind RV
    The best way to tow a 2019 Mini Cooper convertible is with a tow dolly like the Roadmaster part # RM-2050-1 as this is overall the easiest to set up method and also the only method that fits all versions of your 2019 Mini Cooper. Flat towing with all four wheels on the ground ends up costing about the same, has a much longer install time, and is a harder setup to transfer to future vehicles which is why I prefer the tow dolly method for your vehicle (and others). For lower ground clearance...

  • Can 2017 Chrysler Pacifica Be Towed on Tow Dolly
    When towing a vehicle on a tow dolly like the part # RM-2050-1 you have to make sure the steering wheel locks so that the dolly doesn't end up slamming into the side of the vehicle. If your Pacifica has a steering wheel lock like most do you'd be fine leaving the vehicle in park and wheels forward. I looked up your vehicle and it can be towed on a tow dolly.

  • Replacement Straps and Ratchets for a Roadmaster Tow Dolly RM3477 item # RM-2050-1
    Hey John. For the Roadmaster Tow Dolly RM3477, our item # RM-2050-1, the replacement Tie-Down Ratchet is # RM-2110. The replacement wheel strap is item # RM-2150. These are sold individually so you'll need two of each. I am sorry we do not have a replacement slide bar and it doesn't look like Roadmaster offers one either. Where did you get your tow dolly? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

  • Recommended Flat Towing Components For A 2016 Kia Soul
    Hi Juan, You'll want to double check your owner's manual to confirm that your specific model can be flat towed first. If it can not and the manual states that you can dolly tow instead then you can use the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1. Typically the manual transmission model will be able to be flat towed and the automatic transmission models will need to be dolly towed. If it can be flat towed then I have the following flat towing component recommendations: Baseplate:...

    If your 2021 Lincoln Corsair is a front wheel drive then you can use your tow dolly, like the Roadmaster # RM-2050-1, according to the Lincoln owner's manual. For a rear wheel drive or all/wheel/four-wheel drive you'll need to tow it with all 4 wheels off the ground like with a trailer. It's always best to check your copy of the owner's manual to make sure this is still accurate.

  • How To Adjust The Width Of The Ramps On The Roadmaster Tow Dolly
    When it comes to adjusting the ramps on The Roadmaster Tow Dolly # RM-2050-1, you will have to un torque the bolts and then you can slide the ramps to the left or the right to correspond to the width of towed vehicle's tires. Make sure to align the ramps so that both tires will be centered on the ramps, and so that the ramps will be an equal distance from the center of the axle. If the ramps are not adjusted as described above, the dolly may veer to the left or the right during towing,...

  • Recommendations for Towing a 2017 Fiat 500 Behind a Motorhome
    If you have the automatic transmission, then your 2017 Fiat 500 FWD must be towed using a tow dolly like # RM-2050-1. This is due to the transmission design style to prevent damage. If you have the manual 5 speed, you can tow it as it with a speed restriction of 65 mph. If you have the manual 5 speed transmission, I recommend the following: *Roadmaster EZ2 Base Plate Kit - Removable Arms # 522013-1A *Roadmaster Falcon 2 Tow Bar - Motorhome Mount - 2" Hitch - 6,000 lbs # RM-520 *Safety...

  • Can a 2010 Honda Accord be Flat Towed Behind a RV
    According to Honda, the 2010 Honda Accord cannot be flat towed with all 4 wheels on the ground. Your best option to tow your vehicle will be to use a tow dolly like the Roadmaster Tow Dolly w/ Electric Brakes, # RM-2050-1. The tow dolly will allow your Honda to ride with the front wheels off the ground which will guarantee that you will not damage the vehicle's transmission. I also recommend the Roadmaster Universal Hy-Power Diode Wiring Kit, # RM-154, for a lighting solution. The kit...

  • 2019 MINI Cooper S with Automatic Transmission Compatibility with Tow Dolly and Bike Rack
    Based on your owners manual it does appear you can dolly tow your 2019 Mini Cooper Automatic with the front wheels off the ground but I recommend checking with your dealer for distance or speed restrictions because the owners manual only references emergency towing and gives both a speed and distance restriction of 30 miles and 30 mph with no reasoning behind those restrictions. If you find you are able to tow dolly a 2019 Mini Cooper S, then the Roadmaster Tow Dolly with Electric Brakes...

  • Can Curt Echo Brake Controller Be Used with Tow Dolly Electric Brakes
    Some car dollies have electric brakes which the Curt Echo Mobile part # C51180 would work great with. Some dollies have surge brakes which don't require a brake controller as their braking system is essentially self contained. If the dolly are considering has electric brakes though this would work great with it. For a tow dolly that has electric brakes we have the part # RM-2050-1.

  • Can Any Kia Vehicle Be Flat-Towed
    For Kia vehicles, flat-towing would depend on the models and how they are equipped. For example, a 2012 Kia Soul can only be flat-towed if it has a manual transmission. If the 2012 Soul has an automatic transmission, a tow dolly like part # RM-2050-1, or a trailer is recommended. To be sure about the possibility of flat-towing any vehicle it is always a good idea to check the owner's manual or with the dealership. Many auto manufacturers have specific requirements for flat-towing their...

  • Which 2026 Chevy Equinox Can Be Towed Behind An RV?
    Hi Michael! I did a bunch of research and found some stuff. You can only tow a 2026 Chevy Equinox front wheel drive with a gasoline engine behind a motorhome, but NOT with all 4 wheels on the ground. You would have to use a dolly, like the Roadmaster Tow Dolly with Electric Brakes - 4,250 lbs # RM-2050-1. All wheel drive, Hybrid, and EV models can only be towed on a trailer with all 4 wheels off the ground. Do you already have a 2026 Equinox, or are you deciding still?

You can dolly tow with either an automatic or manual transmission. So a Tow Dolly # RM-2050-1 is likely going to be what you want. If you have a manual transmission and want to tow all 4 wheels on the ground please let me know and I can list the parts you will need. That install is likely going to require you to go to a local shop to have everything...

    I did some checking and it looks like the front wheel drive versions of the 2017 Ford Escape can be towed on a tow dolly. The 4WD versions cannot though. The Roadmaster Tow Dolly part # RM-2050-1 would be a great option for a tow dolly. It's our best priced option and would work well. To use the dolly's brakes though you'll need to install a 7-way in place of the connector that's on it with the part # PK12706.
