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:

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 Tow Dolly for 2000 Volkswagen EuroVan
    Based on my research your 200 VW EuroVan has a curb weight of 4,220 to 4,348 lbs. The GVWR is the maximum loaded weight, curb weight (weight without passengers or cargo) is what we use to determine the correct tow dolly. Since you're either at or over the maximum vehicle weight for the # RM-2050-1, I recommend the Demco Kar Kaddy X Tow Dolly # DM9713093. The Kar Kaddy X has a maximum vehicle weight of 4,800 lbs so that easily covers your van. It also has surge brakes instead of electric...

    There are some great options for towing your 2018 Ford Flex FWD with your Class C motorhome, but unfortunately the Roadmaster Tow Dolly # RM-2050-1 will not work for your vehicle. This tow dolly has a weight capacity of 4,250 lbs. Based on my research, your Ford Flex has a curb weight (without cargo or passengers) of about 4,440 lbs. Instead, I recommend the Demco Kar Kaddy X Tow Dolly # DM9713093. This tow dolly has a 4,800 lb weight capacity and can install easily on the rear hitch of...

  • What Wiring Harness Connects 2015 Buick Encore To RV?
    I did some research and from what I found your 2015 Buick Encore cannot be flat towed with all 4 wheels on the ground. If your vehicle is All-Wheel-Drive (AWD) then it must be towed using a trailer. If Front-Wheel-Drive (FWD) then it must be towed with a tow dolly. Whether your Buick is AWD or FWD, confirm the towing options per your owner's manual. If FWD then I recommend the Roadmaster Tow Dolly: Roadmaster Tow Dolly Item # RM-2050-1. Tow dolly has a pivoting deck for easy maneuvering...

  • Tow Dolly Recommendation for Towing 2017 Ford Escape Front Wheel Drive
    I did some checking and it looks like the front wheel drive 2017 Ford Escapes can be flat towed with a tow dolly. The Roadmaster dolly part # RM-2050-1 would work well for this. The steering wheel of the vehicle needs to be locked otherwise the vehicle will pivot on the dolly and the fenders will hit the body of the vehicle.

  • How To Unlock the Steering Wheel While in Tow on a 2003 Volkswagen Jetta Wagon
    The owner's manual for your 2003 Volkswagen Jetta Wagon should give you the correct procedure that is needed to unlock the steering wheel while in tow (if applicable). The flat towing procedures such as unlocking the steering wheel are usually under a section titled, "Recreational Towing". I was not able to reference the online version of your owner's manual unfortunately. With that being said, if you turn the key into the "ACC" position then that will unlock the steering wheel on most...

  • Solution for Carrying Bike Rack With 2022 Mini Cooper JCW Convertible
    I do have a solution, but there are no custom fit hitches available for any version of the 2022 Mini Cooper. Since you have the convertible that also rules out a trunk bike rack and a roof rack bike rack. What you can do is take the # E17 to a fabricator and have them fashion a custom hitch for you. This would allow you to use a hitch mounted bike rack like the Kuat NV 2.0 # NV22B.

  • What Gear Should a 2008 Honda Accord Be Placed In While On a Tow Dolly
    The 2008 Honda Accord when being dolly towed on a tow dolly like the Roadmaster Tow Dolly with Electric Brakes part # RM-2050-1 should be placed in park. That said, I do urge you to confirm this in your owner's manual as well since there will more than likely be other instructions you need to follow as well.

  • 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 that...

  • Flat Tow 2010 Honda Civic
    My understanding is that Honda states the Civic shouldn't be towed behind a motorhome. It is stated that 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, "emergency Towing". However, we have also discovered a lot of references in the online forums from folks who tow their Civics without incident. If you decide to tow the vehicle, you will need base plates first. You will also need a tow...

  • Flat Towing Recommendations for 2015 Honda Fit
    According to the owner's manual for the 2015 Fit, Honda doesn't recommend flat towing the vehicle. I did some research online and found that using a tow dolly like part # RM-2050-1 is the recommended method for transporting the vehicle behind a motorhome. A tow dolly will typically have taillights, but the extra visibility provided by a set of the # RM-2120 EZ Mount Tow Lights would be a great idea from a safety standpoint. The tow dolly uses electric brakes, so you'd need a brake controller...

  • Drivers Side Brake Light Replacement for Roadmaster Tow Dolly with Electric Brakes
    I checked with Roadmaster for you about a replacement lens, and there is not one available for that light, which means that you are going to need to replace the entire assembly. The correct part is the Replacement Driver's-Side Stop/Turn/Tail Light # RM-300220-40, which works with the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1 and RM-2000-1(Discontinued). Also, for future reference in case you ever need to replace the other light, the correct part is the Replacement Passenger's-Side...

  • Unlocking Steering Wheel to Tow Kia Sorento with Tow Dolly
    You should be able to just turn your key to the first position on your Kia Sorento, which will unlock the steering wheel without actually turning the ignition on or energizing anything in the vehicle. Before towing your Sorento with a tow dolly, I highly recommend checking your copy of the vehicle's owners manual for any specific restrictions or guidelines when it comes to towing it behind an RV. This section is usually titled "Recreational Towing" and it will often provide a step-by-step...

  • Can a 2015 Nissan Versa Note be Flat Towed Behind an RV with All 4 Wheels on the Ground
    From my research your 2015 Nissan Versa Note has a Continuously Varialble Transmission (CVT) which cannot be flat towed with all four wheels on the ground. It must be towed on a tow dolly or a trailer. We offer tow dollies from Roadmaster that you can use. Part # RM-2050-1 can be used with your Versa Note. In order to power the brakes on either dolly you need to a trailer connector. I recommend using our kit # HS381-9000 because it includes everything you need except a brake controller.

  • Compatibility of Tow Dolly for 2017 Honda Odyssey
    Yes. The 2017 Honda Odyssey must be towed on a tow dolly. Towing it with 4 wheels down behind your motorhome would damage the transmission. Towing with the front wheels off the ground is an acceptable way to tow your vehicle according to your owners manual. I did a little research on your vehicle and the curb weight is between 4,396 lbs and 4,613 lbs depending on your features. This will make it too heavy for the Roadmaster Tow Dolly with Self-Steering Wheels and Electric Brakes -...

  • What is the Length and Tongue Weight of Empty Roadmaster Tow Dolly # RM-2050-1
    I have some measurements of the Roadmaster tow dolly # RM-2050-1 for you. From the front tip of the coupler back to the pivot bolt (which is about at the centerline of the axle) is 86-1/2 inches. 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 the...

  • How To Flat Tow A 2013 Chevrolet Captiva Sport
    I reviewed the owner's manual for your 2013 Chevrolet Captiva Sport and would agree with you in that your vehicle is capable of being flat towed. However, the two wheel drive version will need to be flat towed with all four wheels down whereas the all wheel drive model will need to be towed with only the rear two wheels down using a tow dolly. For a two wheel drive model you will need a base plate kit, tow bar, safety cables, wiring harness, and supplemental braking system. For the base...

  • Does Roadmaster Tow Dolly RM-2050-1 Come Assembled
    The Roadmaster tow dolly # RM-2050-1 does not come assembled and we do not have a way to ship it in its fully assembled state. Assembly is not all that difficult; you're basically turning wrenches. I have included links to the instructions for you so you can see what is involved in the installation process. I have also linked a video review of the dolly for you. Any local mechanic in your area would have a very easy time assembling it though if you wanted to go that route.

    The Roadmaster Tow Dolly with Electric Brakes # RM-2050-1 has the weight capacity to handle the 2017 Toyota Highlander XLE. The wheel size gives you a 29.6 inch diameter wheel that will require different wheel straps.
