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. These wheel nets are currently the largest option they have for this tow dolly. Please keep in mind that the...

  • 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...

  • 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...

  • 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...

  • 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.

  • 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.

  • 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.

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 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,...

  • 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 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...

  • 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.

  • 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...

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.

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.

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...

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.

I recommend using the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long # 277-000141 to complete the wiring on these tow dolly options as they come with wiring but not the completed 7-way.
