To remove, simply twist the arms back and pull them out. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs, as well.

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

Customer service is 100 percent. Olivia knew about everything I needed and reminded me of something I forgot I needed. She shipped my parts overnight and they were on my porch first thing this morning. I will ALWAYS recommend etrailer to anyone that ask.

Fit as intended. Have pulled the truck approx 3000 miles, no issues.

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:

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:

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:

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:

The whole etrailer family has been great to deal with.

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:

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:

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:

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



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:

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.

  • Supplemental Braking System for Jayco Seneca Towing 2019 GMC 1500 That Installs Out of the Way
    I don't know much about the Readybrute Elite towbar since it's not a product that we offer, but from what I was able to find it looks like they're compatible with a number of different manufacturer's base plates. If you do need base plates to connect it to, I recommend using the Blue Ox # BLU54VR since they will be compatible with your Blue Ox clevises. When it comes to supplemental braking that has the cleanest looking installation that you'll barely notice once it's on your vehicle,...

  • Tow Defender Screen Protector for 2019 GMC Sierra 1500 with EZ-5 Direct Connect Base Plate Kit
    Since you are wanting to use the EZ-5 Direct Connect Base Plate Kit # RM-523198-5 with the Roadmaster BlackHawk 2 All Terrain # RM-422 for your 2019 GMC Sierra 1500 you need to use the Roadmaster Tow Defender # RM-4750 instead of the Roadmaster Tow Defender # RM-4700. If you already own the 4700 version then you'll need the Base Plate Kit # RM-523198-4 instead. I have confirmed all of this with Roadmaster.

  • Can 2019 GMC Sierra 1500 Denali be Flat Towed and Parts Needed
    I took a look at the owner's manual for a 2019 GMC Sierra 1500 Denali and both it and the standard 1500 can be flat towed so long as it is a four-wheel drive with a two-speed transfer case, and according to page 236 of the manual, "To shift the transfer case, press the desired button" which seems pretty simple compared to some other vehicles! There are a number of parts you are going to need in order to flat tow this truck, which I'll list for you: - Base Plate Kit: Roadmaster Crossbar-Style...

  • Is Drilling Required When Installing The Roadmaster Base Plate RM-523198-4 On A 2024 GMC Sierra 1500
    No, you will not need to drill into the frame when installing the Roadmaster Base Plate # RM-523198-4 on a 2024 GMC Sierra 1500. Installation will require some trimming/cutting of the plastic bumper fascia, as well as potentially the spoiler, air dam or grille. Tow hooks, if present, will be permanently removed. I have linked the manufacturer instructions below if you want to take a closer look.

  • Will Roadmaster Base Plate Kit Interfere With Adaptive Ride Control System On 2020 GMC Sierra Denali
    I reached out to my contact at Roadmaster and he confirmed that the Roadmaster Direct-Connect Base Plate Kit # RM-523198-5 and Crossbar-Style Base Plate Kit # RM-523198-4 will NOT interfere with the adaptive ride control system on your 2020 Sierra 1500 Denali 4WD Crew Cab with the 3L diesel. With that being said, I recommend the Direct-Connect # RM-523198-5 as it offers the same rigidity as the Crossbar-style, but will be one less thing to deal with when installing your tow bar. I included...

  • 2020 GMC Denali 1500 Flat Tow Setup
    To flat tow your GMC Sierra 1500 you'll need base plates, a tow bar, safety cables, a wiring harness, supplemental braking system and possibly a high/low adapter if the installed height of the base plate is more than 3 inches higher or lower than the receiver height of the motorhome. For base plates, the Roadmaster # RM-523198-4 you'd looked at would be a fine choice. From what I've seen online, the weight of the Sierra 1500 Denali maxes out at around 5000 lbs, in which case the Roadmaster...

  • Where To Mount the Flat-Tow Electrical Connector on a 2019 GMC Sierra 1500
    The best place to mount the electrical connector is directly to the front bumper fascia, below the chrome moulding. I have attached a few photos of this for you as well on the Roadmaster Crossbar-Style Base Plate Kit part # RM-523198-4 but it shouldn't really matter which kit you have. If you don't already have a flat-tow wiring harness for your vehicle then I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267 because it will then allow you to incorporate...
