Video Transcript for Roadmaster EZ4 Base Plate Kit Installation - 2015 Dodge Durango

Today on our 2015 Dodge Durango, we're going to be taking a look at and installing the Roadmaster EZ4 Base Plate Kit with removable arms. Part number RM-521449-4. This is what the base plate looks like when it's installed on the vehicle. As you can see, there isn't a whole lot that sticks out really far. Right here we just got the wiring sticking out for our wiring that's able to mount to these little brackets that are part of it right there. You got a little hook on either side for your safety chains, and right here, is where the arms for the base plate with the brackets on the end go into place.

You can see, it's got a nice black powder coat finish which is going to help resist rust and corrosion. It's particularly nice because, with this flush and as much as does not show on this, it does maintain a pretty normal, clean look if you're not hooked up to your RV. Now, on this particular one, right here it's got the sensor for adaptive cruise control. This base plate does fit behind that properly so that it doesn't interfere with the function of that as well. In order to install the arms with your brackets, just want to slide them into place, spin them, and they're locked in place. In order to remove them, pull the pin, rotate them back, and pull them back out.

This system makes setup for towing your vehicle very easy. It's a really nice setup and it's really easy to use. Now, let's show you how to install it on the vehicle. First thing, in order to get started on our install, we're going to need to remove our front fascia here. In order to do that, we'll start with taking out these fasteners that are up top. Just work the center out of it.

Then work underneath it. If you've got a trim panel tool, that works perfect. Otherwise, you can use sidecutters as well. After we've got those removed, lets remove these outer ones as well, using the same process to get them out of there. We'll do that on both sides too.

Now we need to remove these four fasteners. We've got a ten millimeter bolt up here, eight millimeter down here. These are some little plastic rivets so, in order to do these, I'm going to take a small Phillips head screwdriver and just kind of push the center out. Quick little tip for you, to make this a little bit easier with these fasteners, you can turn these wheels inward, then I can use that trim panel tool. Just pull those out of there. Let me grab my ten millimeter and my eight millimeter. Take those out. Now underneath we'll need to unbolt this splash guard because some of the fasteners for it are also holding on part of the front fascia. These ones up here, ten millimeter. Then with the ten millimeter you also got two more up here. One on either side. Now we've got five pushpin fasteners under here we're going to take out. The first one's right here. Get that center pulled out, pop the fastener out. Then we've got four more up here, right inside the front lip of that fascia. Once we've got those out, we can remove these three little twist fasteners. You can just twist by hand. If they're a little stiff you can just grab a pair of pliers. Twist them like that, take those out. Finally, to finish taking the splash guard out, there are two thirteen millimeter bolts right back here. We'll take those out, then we can lower the splash guard out of the way and set it off to the side. while we're still under here, and we've got all this paneling off underneath, so we've got more access. We're going to go up and take our fog light connectors off. They're just little tabs on either side you can just pull out. Pull it off there. We're doing that because these fog lights are going to come off with the fascia, and we don't want to pull and damage this wiring at all. We'll do that on both sides. Now that we got all of our fasteners removed, we've unplugged our fog lights, what we're going to do is get ready to take our fascia off. In order to do that, first thing we need to do, so we've got this fender flare here. It just kind of pops into the fascia by those three clips right there. We want to take those out on both sides. We can just kind of reach in behind the inner fender and pull outwards, so that right up here, it'll pop out. Then, we'll be able to start working it off the front. I definitely recommend having a second set of hands for this. We can just carefully remove our front fascia. We can set that out of the way, someplace where it won't get damaged. Now we've got the fascia off. Here's the piece that connects the fascia up to this radiator core support. That could just hang on a little bit just because right there, it hooks over the core support. If that's hanging there, you can just take it off and set that right over with the fascia as well. Down here we've got the adaptive cruise control sensor and there's a little Christmas tree clip that holds this wiring in place. We just need to take that wiring and move it. Pop that clip out of there. You definitely don't want to unplug the wiring for this sensor or move the sensor at all because then you'll likely have to go to the dealer to have it reset. You're going to take this lower thirteen millimeter that's on this core support and we're going to take that out. We'll do the same thing with the other side. Next, we'll install red loctite on our bolt using part number LT37420. We're going to be doing that for all of our hardware. Now, grab a second set of hands. You'll just take this little inaudible 00:06:52 slide it up behind the adaptive cruise control sensor. Line up your hole and use the original bolts that you took out from there. You'll want to get those started, then you'll be able to run those down most of the way in order to help hold this nice and secure. Right back here, kind of in the corner of the bracket, there's a threaded hole up there. We'll be able to take one of our ten millimeter bolts with some loctite on it and get them started into the hole. Just going to get those in there a little ways. Now we'll take one of these two inch long half inch bolts and that spacer. I'm going to slide that spacer right up between our face plate and our bumper bracket there. I'm going to put a flat washer on the underside of it, slide it up through there. Flat washer followed by a lock washer, then the nut. We'll do that on both sides, then we can start tightening everything down. Now we've got this extra little support bracket and it's going to bolt to the frame right up front here. Get that started. Now that we've got that bolt started up into the frame rail we can come to the front here, put our shorter half inch bolt through, and then put our lock washer and nut onto the backside, run it down hand tight. Be sure to do that to the other side as well. Then we can start tightening down our fasteners. Now that we've got everything tightened down, we can go around and make sure that everything's torqued to what's in the instruction manual. In the back of the instruction manual there's a guide as to what each bolt should be torqued to. If you have a breakaway switch for your braking system, which is not included with the base plate kit, now would be a good time to install that. I went ahead and put the front fascia back on just far enough that it'll hold in place. I didn't clip everything back in. I did this in order to be able to mark out where I need to cut out in this grill in order for these things to be able to come through. Just looking at the hook ups here. Seeing about where I'm going to need to go. It's good for about there. It looks like this should come through. If it doesn't, I can just kind of clip around it once it's in. I'm going to clip that out of there. Pretty good for that one, now I'll go do the other side. Put it back up into place. Once you get the center put back, you want to make sure this gets pushed back up over the locking tabs. Push back in place. Same with these over here on the side. Just kind of pop them back in there so they're locked, and you be able to put your little fender flare back in place. In order for this to fit back up just inside the fascia here, we're going to have to cut these, because with the base plate up there, these aren't able to fit, because it hits right up here. We're going to need to do that on both sides. Now we should be able to reinstall this and we can start putting in some of our pushpin fasteners. We can also put our little twist tab fasteners back in and then from there, we'll put this up and reinstall it the way it came off. Now that our bumper's all back on, we still got to attach the inner fender wire back over here. Let's not forget to plug our fog light connectors back in. Then, back in the fender, we'll reinstall our screws. We're not able to reuse those little plastic rivets that we're right here, so I'm just going to grab a couple of small pushpin fasteners to re-secure those in place. That's going to complete our look at the Roadmaster EZ4 Base Plate Kit with removable arms, part number RM-521449-4 on our 2015 Dodge Durango.

by:

This was a straightforward install. The instructions were easy to understand and follow. All the necessary parts and hardware were included. It is pretty well hidden once installed. I highly recommend this base plate and etrailer.



by:

great fit. a slight cut needed to be made in the bumper bracket to facilitate the round tube to fit through the bracket. but, other than that, it was an easy install took about 2 hours if you include the coffee brakes. this part is highly recommended. Fast shipping. the beast human service. thank you.

Had Base Plate installed today, shop gave me 2.5 hr labor time. I returned just under 2hrs and they were backing my car out the shop. They parked it facing me. I told the Mechanic "That was quick" He said that's because it wouldn't fit. I was disappointed and asked what do I owe you for your labor> He laughed out loud and said it on there, but hard to see. I was so surprised and pleased you have to just about get down on your knees and bend down to see it. took me about 8 min to install everything and connect it to the Tow vehicle. I'm very pleased with it.



by:

Working great on my Fiat 500l with the automatic euro transmission. Towed over 10000 miles and was easily installed using etrailer video instructions. Yes you can tow a Fiat 500 with the automatic euro transmission. The firmware was flashed on a recall and revised in the manual. Most dealers don’t even bother checking for the latest version.



by:

So far has performed very well. Was easy to install and hookup is pretty quick and easy. You install instructions were very thorough. Practically invisible when not in use. Tried to attach two pics, but would only take one.



by:

Works perfect and very hidden. Cannot even tell it is on my Honda HRV. Installation was time consuming since this was my first on a Honda. Your video did make things go smooth. I would buy this item again.



by:

Ordered Product on Saturday afternoon, delivered on Wednesday, Installed on Friday. My 23 Wrangler Sahara 4Xe did take the spacer and washer on each side of the frame and was no problem getting them to fit. The lower passenger outside nut that holds on the bumper will not tighten down all the way, the flange of the factory nut gets caught in a slot in the base plate on that side. Will look into a standard nut to see if that will work - it is tight against the slot and holding.



by:

Super-cool. It's been a year. I installed it myself and it was way less of a task than I expected. The fitment of this was incredibly spot on (no "tweaking" or drilling). Performance wise . . . it does what you expect. You insert the removable "arms", clip in onto your tow bar, and when you get to your destination the vehicle is still attached to your tow bar. Quality product.



by:

I’m always extremely satisfied with Roadmaster products. I had just bought a new truck and planned on towing it so I needed everything to get it ready to tow. This review also applies to to the other items I purchased.



by:

I installed this kit on my 2015 Honda Fit. The instructions are very good, however, there are a couple of "snags" to watch out for. You might have to enlarge the holes on the blind hole part of the bumper installation in order to get all of the mounting bolts to align. The other recommendation I have is NOT to use the Loctite "red" thread compound on the blind hole bolts where you cannot get a wrench on the inside. The Loctite will dry too fast and cause issues tightening the bolts on those areas. They have lock washers anyways and you can use the Loctite on the bolts you can get a wrench on the backing nut mounts. I have been towing for months now and I am very happy with it, especially the crossbar style. You will have to purchase the crossbar separately. It's more weight and a little clunky compared to the direct attachment but it allows you to disconnect in some tough situations by pulling the crossbar off while one arm of the tow hitch is still attached. I use an Falcon All Terrain tow bar so I can release the tow arms in uneven conditions. And I have encountered all types of uneven ground, it really makes disconnect of the TOAD very easy.



by:

Good fit, works well. Very happy with the base plate after 1st year of use.
etrailer staff was very helpful with my questions, making certain I got the base plate that was right and advice with minor problems I had with installation.



by:

The Jeep project went very well everything fit great and worked well. I really love Roadmaster products and quality and your company is the best place to purchase them. I sold the Jeep and replaced it with a new 2019 Chevy Equinox 2.0 L AWD and just purchased and installed the following items from you and installed them, RM-156-25 & RM-156-75 Battery Charge Line Kit, RM-146-7 Flex Coil Kit, RM-523193-4 EZ4 Plate Kit, RM-88333 Custom Seat Adapter, RM-751489 Stop Light Switch Kit and a RM-98160 Second Vehicle Brake Kit w/brakeaway. All these parts were in stock and arrived quickly and normal with you people, I really enjoy the o-line vidios as I do all my own installs. Thank you so much for your great service.
I will attach pictures of my install, you will see how I was able to fab a bracket and attach it to the existing mount on the base plate to mount the brakeaway switch and the air connection for the brake system.
I also fabricated a tail light bar as I didn't want to use mag-lights or splice into the factory lights and bulbs installed into the lights would not work as the factory brake lights will come on when the brake system is applyed and the turn siginals would not be visable.
Thanks for all you do, I would and do recommend you people to everyone who needs your products. Rob

Great product for my 2014 Wrangler. Good materials, solid attachment to vehicle, and looks good. The e trailer installation video was great for assisting installation. Made the install much quicker and easier. The most difficult procedure for me was disconnecting the wiring harness on the back of the bumper. An old tack puller (or tool of similar design) would have been great for leveraging the pins out of their holes. Cutting the air dam was a slow process to ensure I didn't cut too much. A paper template to mark where to cut the air dam would make this process much simpler. Again, I can't emphasize enough how great the installation video was for making the steps easier.



by:

etrailer service was great. Received my Roadmaster base plate in 3 days. The directions from Roadmaster were fair, but etrailer's video was excellent. I had trouble mounting my base plate as the space between the two baseplate ends were too tight. I needed to use a floor jack and bottle jack to get it on. Once it was in position everything went together fine. I trimmed the Jeep' air dam differently keeping the ends that Roadmaster wants you to cut off. I think it looks better. I also had to modify the center cut in the air dam to accommodate the breakaway switch I have.



by:

The whole etrailer family has been great to deal with.



by:

2019 Ford Fusion Energi. A lot more trimming required on the facia than noted in the instructions, but I'll chalk that up to running changes I suppose. I used a combination of a Sawzall with a fine blade and a Dremel tool, both worked well. In the end, it took me about 8 hours (over two days) to install, and had it's challenges. I had to do some pulling and tweaking to get holes to line up, and the already mentioned extensive trimming of the facia. Overall well designed product, and of course etrailer was excellent in shipping.

Side note, adaptive cruise control is not affected when the drawbars are removed. With the bars in and the towbar mounted (it's a Stowmaster car mounted bar) the cruise control works just fine as an old fashioned CC, the adaptive part just doesn't work (it won't slow down for you when a slow car is in front, because it can't see around the tow bar). Basically perfect and what I was hoping would happen.



by:

Unfortunately first set was defective from Roadmaster. Etrailer sent another set and return label which installed correctly, eTrailer was great to work with.



by:

Solid product well make easy install



by:

Installed myself with help of one friend. Assistance with install using the videows was invaluable. The installation on a brand new vehicle brought praise and comments on how clean the install looked. Great job etrailer.



by:

So far so good. It arrived sooner than expected. Very pleased. Installing it tomorrow. I’ll try to update later.



by:

Baseplate did not fit vehicle. Apparently it was manufactured icorrectly. All other baseplates for this vehicle were also manufactured improperly so engineering had to come up with new install procedures. Took a week to make that happen. Also, received new Easy Connect modules that are identical to one I already had.



by:

Fast delivery, correct parts, excellent installation instructions, and everyting fit! I would buy from this seller again.



by:

Followed directions and completed job in a little over 4 hours. had trouble reinserting some pins in difficult locations.

Later in the month I installed the wiring tow package. Goofed up and crossed a wire and it took me two days to get back under the truck and rewire. all is working great according to directions...…….

I will use etrailer again, good service, great service representatives...……..jt



by:

Perfect fit no trimming to grill



by:

great kit to add a baseplate to my 2019 jeep wrangler. It takes several hours for one person to install, but if you follow the instructions and watch the video it's straight forward and easy to install.

  • Can Base Plate Kit and Front Trailer Hitch be Installed on a 2015 Dodge Durango Together
    Since a base plate kit like the Roadmaster EZ4 Base Plate Kit # RM-521449-4 and the Curt Front Mount Trailer Hitch Receiver # C31033 take up the same space on your 2015 Dodge Durango you would only be able to have one installed at a time. Since new hardware would need to be used each time either of them is installed the best one for you would depend on what you plan on using your Durango for. If the main purpose is to flat tow then you need the base plate kit. If you were planning on using...
