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...

  • Should Vehicle Towed on Tow Dolly be in Park or Neutral
    When flat towing a vehicle you need to first check the owners manual to see what the recommended procedure is for towing it on a tow dolly like the # RM-2050-1. In most cases you need to put the vehicle in park as most vehicles are front wheel drive but if the vehicle was rear wheel drive it would need to be in neutral if the vehicle could be towed with a dolly. Also the steering wheel will need to be locked out as well.

  • 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.

  • Tow Dolly for a Full Size Truck with Front Track of 79 and 78 Inches
    The best tow dolly we offer is the Roadmaster Tow Dolly with Electric Brakes part # RM-2050-1. Dolly includes all lightging as well for DOT compliance. The only thing one would need to use this dolly is a trailer connector like part # PK11604 for a 6-way or part # PK12706 for a 7-way. This dolly will accept a vehicle with a front track up to 76" wide which would seem to be a bit too narrow for your application. The dolly also only accepts wheel sizes from 12" - 16" therefore would also...

You will load the front wheels, put the vehicle in park, put on the parking brake, connect the wheel nets and then release the parking brake prior to towing. You will need to connect the wiring of the Roadmaster Tow Dolly using the Pollak # PK12706 to match your motorhome wiring. I checked your owner's manual and this car can be flat towed if you prefer.

  • Parts Needed to Flat Tow 2015 Manual Transmission Mitsubishi Mirage Behind Motorhome
    A 2015 Mitsubishi Mirage with a manual transmission can indeed be flat towed with the transmission in neutral. For starters, you'll need a base plate, # BX2002 from Blue Ox. For a tow bar, use the Blue Ox Alpha2, part # BX7380. To wire the taillights, I'd recommend a bulb and socket kit like # RM-152-LED-7 which allows the wiring to remain independent of the vehicles taillight wiring system. It's like using a magnetic mounted tow light set that you'll only need to install once, without...

  • Can 2021 Lincoln Corsair be Towed Behind Motorhome
    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.

  • 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...

  • Does Steering Wheel of Vehicle Need to Lock to Tow On Tow Dolly
    When towing a vehicle on a dolly like the part # RM-2050-1 that you referenced you need the steering wheel to be locked so that around corners the dolly fenders don't hit the door or fender of the vehicle. If your steering wheel doesn't lock when the key is off you can use your seat belt to lock it. Wrap the seat belt a couple times around the steering wheel and then buckle it in place. Now pull the seat belt all the way out so that as you let it retract it locks. Now your wheel will be locked.

  • 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...

    Tire wear on the inside tread of both tires would not necessarily be caused by any alignment problems. It could also indicate that the dolly was likely overloaded which could mean that there are parts that are damaged and need to be replaced. Inspect the parts as you go through the instructions below. There are alignment instructions though depending on the tow dolly you have. For # RM-2050-1 follow these instructions: 1. First make certain the steering pin (Figure 1) is in place. 2....

  • 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?

    According to the owners manual for your 2009 Scion xD it can only be flat towed with all 4 wheels on the ground if you have a manual transmission. 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...

    According to the online version of the owner's manual for your 2016 Kia Soul, the version with automatic transmission cannot be flat towed with all wheels on the ground. This is noted in section 6-27 of the manual. The car's front wheels must be elevated and placed on a tow dolly like # RM-2050-1 from Roadmaster. This type of dolly requires a brake controller like the Prodigy P2 # 90885 to operate the electric brakes.

  • Tow Dolly Recommendation for Towing 2018 Toyota RAV4
    The Roadmaster Tow Dolly part # RM-2050-1 would be a great dolly to use to tow your 2018 Toyota RAV4. Your wheel size would not be an issue either. This comes with wheel nets that will fit well and brakes so you'd be set. The Roadmaster Tow Dolly # RM-2050-1 does not come equipped with a breakaway system but you can certainly add one. I recommend the Hopkins # HM20001, because of how easily it installs. They aren't a requirement but it would be a great idea.

With your front wheel drive vehicle in park, turn off your ignition and remove the key. Turn your steering wheel so that it clicks into a locked position. If it will not lock, you will need a steering lock like # WICL303RED. To finish securing your vehicle, prior to attaching it appropriately to the...

    You are correct that passenger and cargo weight inside a vehicle does reduce the trailer weight it can tow. A vehicle like your PT that is intended primarily to transport people may not have much trailer towing capacity if you have a full load of passengers and cargo. I checked the online owner's manual for the 2005 PT Cruiser and the manual states (on page 242) the maximum trailer weight is 1000-lbs when the total weight of passengers, luggage and cargo is no more than 865-lbs.

If your Spark is an automatic transmission it cannot be flat towed, instead you will need the Roadmaster Tow Dolly with Electric Brakes - 4,250 lbs # RM-2050-1.
