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.

  • Can 2018 Chevy Equinox All Wheel Driver Model Be Flat or Dolly Towed
    According to the owner's manual, only Diesel AWD models are capable of being flat towed, and AWD equipped vehicles are not capable of being dolly towed. Otherwise, the only way to tow the vehicle without damage is on a trailer. I've done some research, and haven't been able to locate any references that indicate that shutting off the AWD system would enable the vehicle to be dolly towed, I'm sorry to say. If the vehicle is a Diesel, to flat tow it you'd need a tow bar, base plates,...

  • Can 2012 Mini Cooper Be Towed With Roadmaster Tow Dolly
    I checked the owner's manual for towing your 2012 Mini Cooper with the Roadmaster Tow Dolly, Item # RM-2050-1, should be fine. The details were somewhat vague in the owner's manual so check yours for particular instructions because each Cooper model has slightly different features and instructions. This tow dolly includes electric brakes so you will need a brake controller. If you do not have a electric brake controller, I recommend the Redarc Tow-Pro Elite Brake Controller, Item...

  • Tire Weight Rating Questions
    A tire's weight rating is per tire. For example Roadmaster Tow Dolly with Electric Brakes 4,250 lbs # RM-2050-1, uses # RM-200330-80 tires which has a maximum load capacity of 1,570 lbs each. With 2 tires used, the load capacity of the tires doubles to 3,140 lbs. Since the # RM-2050-1 has an overall load capacity of 4,250, if you subtract the load capacity of the tires, 1110 lbs is the left over towing capacity of the tow dolly itself. Overall, the dolly's capacity is not equal to...

  • Can 2017 Chevy Colorado be Flat Towed Facing Backwards
    I took a look at the online owner's manual for your 2017 Chevy Colorado and it looks like you can safely tow your vehicle by putting the rear wheels on a tow dolly. I do recommend verifying this in your copy of the owner's manual under the "Recreational Towing" section as well. If you don't already have a tow dolly then we can help you out with that here at etrailer. If you only plan on towing every once in a while (like once or twice a year) then a cost-effective option is the Roadmaster...

  • Compatibility of CVT Transmission Vehicles with Towing Behind Motorhome
    The answer is no. The CVT transmissions do not allow for towing 4 wheels down. Depending on the vehicle, you may be able to use a tow dolly instead of a trailer. With both of the models you listed, they can use a tow dolly like # RM-2050-1. I've linked the page to all the tow dolly options we carry. You can always look at online owners manuals for information like this to confirm function prior to purchasing a vehicle or taking a salesman's word for it.

  • Can 2016 Ford Flex be Towed On Roadmaster Tow Dolly # RM-2050-1
    Yes, your wheel and tire size is perfectly fine to use with the Roadmaster Tow Dolly part # RM-2050-1 that you referenced. At one point Roadmaster listed this as only fitting up to 16 inch wheels but we've found that's not true currently. The vehicle in the review video I attached has much bigger wheels than that.

  • How to Use 255/75-15 Tires on the Roadmaster Tow Dolly with Electric Brakes Part # RM-2050-1
    Yes, the Replacement Wheel Net for Roadmaster Tow Dolly part # RM-2150 will be correct in order to secure your 255/75-15 tires onto the Roadmaster Tow Dolly with Electric Brakes part # RM-2050-1. This wheel net works with tires up to 30" diameter and your tires are 30.1" diameter which means you will need to let a bit of air out of the tires but nonetheless will still work for you. These wheel nets are currently the largest option they have for this tow dolly. Please keep in mind that the...

  • How to Choose Correct Ball Mount for Tow Dolly
    The tow dolly you are looking to rent or purchase should feature a recommended or maximum ball height for the hitch ball it will attach to. For example, the Roadmaster Tow Dolly # RM-2050-1 that we have available recommends a ball height of 17 to 19 inches. Since you do not yet have the tow dolly in hand, you can contact the seller and ask for its coupler height from the ground to see where the ideal hitch ball position will be on your Sunstar RV. You will then simply take a measurement...

  • Tow Dolly That Will Work With 18 Inch Wheels
    There is a tow dolly that will work with your 2017 Nissan Murano's 18 inch wheels but the Roadmaster Tow Dolly # RM-2050-1 will not work with that size wheel; as you noted it will only work with wheels that are between 12 and 16 inches. Instead, I recommend the Demco Kar Kaddy 3 Tow Dolly # DM9713046 as it does not have the wheel restrictions of the Roadmaster. As you can see by the cut out of the linked instructions, the Kar Kaddy has wheel straps that are designed to fit a wide variety...

    Your 2016 Kia Soul with Sportmatic automatic transmission can be towed on either of the two Roadmaster Tow Dollys we carry as long as you have the 16 inch wheels. The 17 or 18 inch wheels will not work. The factory 205/60-16 tires will work well on either the Roadmaster Tow Dolly with Electric Brakes - 4,250 lbs # RM-2050-1 or the self-steering # RM-2000-1 which will allow the dolly wheels to better track with your motorhome. Either option will offer safe towing for your vehicle. Either...

  • Does Ignition of Vehicle Need to be On When Towing on a Dolly
    All tow dolly procedures would be in the owners manual of your Kia Forte, but in general you do not want to have the ignition on as that unlocks the steering wheel which would cause fender issues around corners when the vehicle is on a dolly like the # RM-2050-1 that you referenced. Having the steering wheel locked is what you'll want.

  • 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...

    Yes, I did some checking and the 2005 Mini Coopers with automatic transmissions can be towed on tow dollies like the Roadmaster part # RM-2050-1 that you referenced. This is actually the only way it's recommended to tow them aside from on a trailer. To use the brakes of this kit you'll need to add a 7-way to it with the # e99011.

    The only way to flat tow a 2015 Chevy Malibu is to dolly tow it. Because of the e-assist feature it is not able to be dinghy or flat towed. I recommend the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1. Your owners manual will allow for dolly towing with the front wheels off the ground. You simply load the front wheels on the dolly, shift to park as usual and then secure the vehicle to the dolly with the wheel nets. This dolly is equipped with electric brakes and all the...

  • Towing a 2008 Kia Rio 5 with a Tow Dolly
    I took a look at an online copy of an owner's manual for a 2008 Kia Rio 5 and it does not mention recreational towing but does say the vehicle needs to be towed with its front wheels on a dolly and rear wheels on the ground. For that we have the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1 which would only require a 5-way, 6-way, or 7-way connector on your motorhome in order to activate the electric brakes of the tow dolly. This dolly makes towing your '08 Rio 5 much simpler...

You should check your owner's manual to verify all of this. If you're able to use a dolly the Roadmaster Tow Dolly # RM-2050-1 is great option. The...

  • How to Tow a 2004 Honda Accord Behind a Motorhome
    I took a look at the online version of the owner's manual and on page 264 it talks about towing your 2004 Honda Accord. They recommend either using a flat-bed or a tow dolly to transport your vehicle. Flat towing it (with all 4 wheels on the ground) should only be done in an emergency situation where neither of the above options are available. We do have tow dollies that you can use to transport your Accord. For your application I recommend the Roadmaster Tow Dolly with Electric Brakes...

  • Comparing Roadmaster Self-Steering Tow Dolly To Fixed Wheel Tow Dolly
    The Roadmaster Tow Dolly with Self-Steering Wheels and Electric Brakes - 4,380 lbs # RM-2000-1 has the advantage of the turning wheels as opposed to the # RM-2050-1. The turning wheels on the dolly allow the dolly and vehicle to better track with the motorhome around corners. This allows for better turning and traction whether on the highway or around corners or gas pumps. The slight movement allows better contract with the pavement because the wheels are not pulled at a slight angle...

To the front of the dolly body it is approximately 73 inches. If the distance is not enough you could always use a longer ball mount to increase the distance some. You may also need a high/low adapter to keep the dolly level. I have linked a help article showing how to measure and a link to...

    You will not need to add safety chains to attach your vehicle to the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1.

The dolly does come with safety chains, but those are for the dolly itself and attach to your motorhome.
