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.

  • 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.

  • How To Flat Tow a 2012 Kia Rio
    I do have an option for you but the 2012 Kia Rio cannot be towed with all four wheels down. However, it can be towed behind your motorhome using a tow dolly, the Roadmaster Tow Dolly with Electric Brakes part # RM-2050-1 is what I recommend. This tow dolly will actually be more cost effective than a full flat-tow setup and it will not cause as much wear on the vehicle as only half of it will be making contact with the road which keeps your front suspension in full working order.

  • Recommended Way to Tow 2012 Jeep Liberty Sport Behind RV
    I prefer recommending a tow dolly for towing vehicles like your 2012 Jeep Liberty Sport behind and RV as the install is much less invasive, the dolly can easily be transferred to future vehicles unlike some of the flat towing components, and by the time you price everything out plus install time the dolly ends up costing less like with the Roadmaster Tow Dolly part # RM-2050-1. This dolly is easy to load, has a steering axle, and comes with brakes so it's a really great option. To activate...

  • Using Tow Dolly With 2016 Ford Edge
    I took a look at the owner's manual for your 2016 Ford Edge to get an idea of what you would need to do when dolly towing with the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1. The only thing mentioned in regards to dolly towing was that "if your vehicle has a steering wheel lock make sure the ignition is in the accessory or on position when being towed." There is no other mention in the manual in regards to being in neutral or the parking brake on or off (though I would assume...

  • Is There Enough Clearance to Tow Fiat 500 on Roadmaster Tow Dolly
    Yes, your Fiat 500 has enough clearance to be used with the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1. I also took a look at the wheel size if your Fiat, and from what I can see it will have either 15" or 16" wheels, which are also compatible with the dolly, so you aren't going to have any issues there either. I have added links below to a couple video reviews as well of the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1.

    I did some checking and your 2016 Ford Edge front wheel drive is towable on a tow dolly like the Roadmaster tow dolly part # RM-2050-1 that you mentioned. The only other thing you'll need is a 7-way upgrade kit part # e99011 which will allow you to add a 7-way to the dolly so that you can control it's included brakes.

  • Can 2014 Toyota Prius V be Towed with Tow Dolly
    I did some checking and your 2014 Toyota Prius V can be towed on a tow dolly like the Roadmaster kit part # RM-2050-1 that you referenced. Your 2012 Chevy Colorado could have a towing capacity of 1,500-5,500 lbs depending on how it's equipped so you'll need to confirm that based on how your truck is optioned.

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.

  • 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...

  • Is Trailer Breakaway Kit Required for Tow dolly
    You do ask a good question. A breakaway system is not required when using the Roadmaster Tow Dolly. And yes, there would definitely be a risk of the towed car jackknifing if the dolly brakes engaged after the trailer decoupling. The rear of the towed car could come around sideways and make a bad situation worse. My technical contact at Roadmaster confirmed that the above information is correct.

  • 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,...

You will likely have to replace the tire with the same size.

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.

  • Can a 2009 Honda Civic be Flat-Towed
    According to the owner's manual for your 2009 Honda Civic, the vehicle can be towed with all wheels on the ground but you cannot tow the vehicle more than 50 miles and you must keep the speed below 35 mph. Therefore, I would assume this is not feasible for flat-towing behind a motorhome so the best option for you would be to use a tow dolly like the Roadmaster Tow Dolly part # RM-2050-1. This dolly has electric brakes, lighting, and safety chains. You will need a trailer connector like...

  • Can a 2012 Kia Sportage with an Automatic Transmission be Flat Towed
    From what I could find it looks like if it is a FWD you can tow it using a tow dolly and if you have a 4WD then it needs to be towed with all of the wheels off of the ground. Unfortunately it doesn't look like you can flat tow your 2012 Kia Sportage though. You can verify this with your copy of the owner's manual or your nearest Kia dealer. If you have a FWD and would like a tow dolly then I recommend the Roadmaster Tow Dolly # RM-2050-1. This has a weight capacity of 4,250 lbs and comes...

    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.

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.

  • 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...

I recommend checking your own copy of the owner's manual to confirm this. We have 2 different tow dollies from Roadmaster that you can use to tow a 2WD model. The first one, part # RM-2050-1, is your standard tow dolly while part # RM-2000-1 has self-steering wheels that make...

  • 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...
