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.
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.

Video Transcript for Roadmaster Tow Dolly with Electric Brakes Review
Today we're going to be taking a look at the Roadmaster tow dolly with electric brakes. Part number RM-2050-1. Using a tow dolly eliminates the need for installing a base plate, installing difficult wiring, or purchasing an expensive supplemental braking system. It's also great if you want to tow multiple vehicles. This tow dolly features electric brakes, and has a vehicle weight capacity of 4,250 pounds. The adjustable wheel nets fit a wide variety of tires.
The ratcheting mechanism makes securing them easy. The deck tilts for easy loading and unloading. Simply pull out the pivot pin, and the rams tilt to the ground. Our ramps are also adjustable in or out to the width of our vehicle. While in motion, the deck pivots for easy maneuvering around corners. Because it has electric brakes, it's going to make for safer stopping, and it's going to reduce the wear and tear on your RV's brakes.
It's fully wired for brake lights and turn signals. It even includes a license plate bracket. Here's our left turn signal, right turn, running lights, and brake lights. It also has two side marker lights. It's made out of a powder coated steel construction, so it's going to resist rust and corrosion.
Our ramps and wheel cradles feature treads for better traction when loading and unloading. The usable width of our ramps at its narrowest position is 34 inches, the widest is at 77 inches. The overall length of the tow dolly is 121 inches. It's width from tire to tire is 102 inches, and our ramps are 16 and a half inches wide. The whole thing weighs 545 pounds.
Due to the size of this item, it ships via freight. Two ST205-75R14 radial tires are included. The axles features easy lube hubs with a grease circ. You can pass a lock through the coupler latch here to keep it secure, and when not in use the coupler handle makes it easy to maneuver. Now that we've gone over the features, I'll go ahead and show you how to get it set up. First thing we need to do is make sure that our RV is parked on a level surface, and that it's inline with our tow dolly. Then we need to be sure that our RV is in park with the emergency brake on. To hook up our tow dolly, we're going to be working with a two inch ball. You will have to provide your own. It needs to be between 18 and 20 inches from the ground up to the top. We've got 19 here, let's go ahead and hook it up. We want to make sure that our coupler is in the unlock position. Just going to raise it up, and set it in place. Once we've ensured it's all the way on, just go ahead and lock it up. Now let's hook up our safety chains. We're going to criss-cross the left and the right. So what that means is our right side is going to go and hook up to our left, and our left is going to go towards our right. Now let's connect our electric. The tow dolly does come with bare wires, so you have to provide your own connection. This is so you can match the connection to whatever your RV has. With our tow dolly secured to our RV, in preparation for loading our vehicle, we need to pull out the pivot pin, which allows the ramps to drop down. So it's going to be located right here. Pull out the clip, and then the pin. You may have to put a little bit of weight on the platform to pull out that pin, and they should just drop right down. Now we're ready to pull up on to our tow dolly. If our towed vehicle has a rock guard, an air dam, or any other undercarriage components, we may have to remove them so we can pull up onto our ramps. Now let's go ahead and pull on. It's a good idea to get an extra set of eyes when doing so. Also, you may have to build up a little bit of momentum to get up the ramps. It could just make it a little bit easier. When you get into the cradles, you can stop. If it's a front wheel drive vehicle that you're towing, you can just put it in park and then you're all set. If it's a rear wheel drive vehicle, you'll need to check with your owner's manual to ensure that it can be towed so it doesn't damage your transmission. Now let's replace our pivot pin. With our vehicle in place, now we need to lock our steering column. If your vehicle is equipped with a steering column lock, that's great. You just need to make sure it's locked, and then we're all set to go. If it's not equipped with one, you'll need to purchase a locking accessory. Now let's secure our vehicle to the tow dolly with our tie down straps. There is a right and a left side. You need to be sure you're working with the correct side. Now I'm holding it up with the center strap. We need to be sure that our hook is facing towards the rear of the vehicle. The center strap is going over the top of our tire. So let's go ahead and set it in place. Let's secure our hook first. We've got three different options. We need to use the one closest to the center of the tire. Now we need to adjust our buckle. The side straps need to be at the nine o'clock and three o'clock position. As you can see I'm a little bit tight here. I'm going to loosen it up, and straighten it up. That's about where we need to be. Lastly, we can run our ratchet strap. We need to make sure it's in the center of the tire. We'll take the strap, we're going to go through our ratchet, I'm going to adjust it to where it's center with the tire, I'm going to pull it nice and tight, and then I'm going to begin ratcheting it down. Once it's all ratcheted down, we can go ahead and tuck up any excess that we may have, and repeat the same process on the other side. With everything secured we're ready to get on the road. Now like when towing anything, it's not a bad idea to check your straps periodically when you make your stops. Here you see it being pulled behind an RV. The front tires are strapped down securing the vehicle to the tow dolly, while the vehicles rear tires are free to spin. The tow dolly provides a smooth ride, even around corners. Note how the platform pivots as the RV turns corners. That's going to complete our look at the Roadmaster tow dolly with electric brakes, part number RM-2050-1.

- Trailer Hitch, Wiring & Brake Controller for 2012 BMW X5
- Both of the 2-inch Class III hitches we have for your 2012 BMW X5, Draw-Tite # 75600 and Curt # 13077, are fairly involved installations as hitches go. The linked video illustrates the installation of the Draw-Tite hitch on a 2012 X5. This hitch is rated for a maximum towing capacity of 6000-lbs but you will want to check your BMW owner's manual to confirm the towing capacity for your particular X5d as equipped from the factory.

- 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...

- 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 # ET7WK.

- The Replacement Driver's Side Fender # RM-922004 does not include the mounting bracket as the mounting bracket for the metal fenders is the axle assembly itself (see attached clip from the installation instructions). Even though this axle assembly is available, when I spoke with my contact at Roadmaster he said that if you are wanting to replace the axle assembly then it would be better to replace the entire tow dolly which we have available as part # RM-2050-1.

- If you have the automatic transmission, then your 2017 Fiat 500 FWD must be towed using a tow dolly like # RM-2050-1. This is due to the transmission design style to prevent damage. If you have the manual 5 speed, you can tow it as it with a speed restriction of 65 mph.
If you have the manual 5 speed transmission, I recommend the following:

- The Roadmaster Tow Dolly electric brakes, like those on the Tow Dolly # RM-2050-1, are standard manual adjust electric drum brakes. You can use a brake adjustment spoon like # W80630 to adjust the brakes out so that there is just a slight but constant drag of the pads on the drum when the wheel is turned.
I have attached a video demonstration that you can check out as well that shows this process. Just fast forward to around the 4:35 mark to see where the installer starts to adjust the...

- I do have some recommendations for flat towing your 2013 Mini Cooper, but please note that on page 257 of your owner's manual it states that you can flat tow your Mini if is has a manual transmission. If you have an automatic transmission then you need to use a tow dolly.
A complete flat towing setup includes a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and a high-low adapter. I recommend going with the Blue Ox Base Plate Kit # BX1307...

- Yes, disconnecting the battery with a Quick-Disconnect, like the Deka part # DW05312, will be the easy way to go when it comes to disconnecting the battery on your 2017 Ford Edge so it can be flat towed.
Disconnecting the battery prevents it from draining while you are flat towing. Since the owner's manual states that the battery must be disconnected I strongly recommend following those instructions and not trying to get by it somehow. That is one of the down sides to flat towing with...

For your electrical connection I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 and then the SMI Stay-IN-Play DUO Supplemental Braking System - Proportional # SM99251 for the supplemental braking system required in almost all states.

- Neither of the tow dollies we carry are going to fit both of your vehicles completely. The closest is the Roadmaster # RM-2050-1. It has size ST205/75 R14 radial tires and electric brakes. However, it will only accommodate vehicles up to 77 inches wide at the wheels and wheels that are 12 to 16 inches in diameter. We do carry larger wheel nets like the Erickson # EM58518 which will fit between 14 to 29 inch wheels.

- 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...
view full answer... - 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...

These include safety cables, a wiring/lighting kit of some kind and base plates and a braking system for the vehicle being towed.
If you will be transporting the vehicle only once, to get it to a single destination, you may prefer to use a tow dolly like # RM-2050-1. Although such an item is not inexpensive...

- Using the Roadmaster Tow Dolly, part # RM-2050-1 for your 2014 Focus will work great. The dolly has electric brakes and has tail lights so the stress will not be on your car when towing.
I recommend the Prodigy P3 Brake Controller, part # 90195. This is a proportional brake controller which means it will apply the brakes on the dolly with the same intensity as the brakes on the towing vehicle. This is one of our most popular because it is easy to install and operate.

- 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. Parts # RM-2000-1 and # RM-2050-1 both can be used with your Versa Note. The main differences between the them are the weight capacity and that # RM-2000-1 has self-steering wheels.

- 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. This is the dolly that does not have wheels that steer on the dolly. The part # RM-2000-1 has the wheels that move and steer.
The steering wheel of the vehicle needs to be locked with either dolly otherwise the vehicle will pivot on the dolly and the fenders will hit the body of the vehicle.

- The Demco Classic Base Plate Kit # DM9518312 for your 2014 Kia Soul measures 21" center to center between the brackets. This means that your current fixed tow bar isn't compatible but we do have a solution for you.
I recommend using the Commander Tow Bar # DM9511010 with the Classic base plate kit. This features adjustable arms and comes with safety cables. The whole kit is rated for 6,000 lbs so you won't have any trouble with your Kia Soul.

Flat towing setups are typically more expensive than this dolly and can't easily be transferred to future vehicles like this dolly can so it's not a terrible option. Plus there's no in-depth install like the tow bar setups can have.

The Roadmaster tow dollies # RM-2000-1 and # RM-2050-1 will accept 12 to 16 inch vehicle tires so as long as the 2016 or 2017 Honda Fit has rims no larger than 16 inch it can be used on either tow dolly.
