Features to know about

Made for a Clean Front End: Hidden Brackets with Removable Drawbars

This setup keeps your front end looking clean when you’re not towing. The crossbar-style hidden brackets stay tucked out of sight, and the square drawbars remove easily using two hitch pins. Once the arms are off, the remaining brackets are virtually invisible—mounted within the grille area where they’re protected from scrapes and scuffs. It’s an easy way to keep a factory look while still being ready to tow when needed.

Solid and Reliable: All-Steel, Computer-Cut Construction

The base plate kit uses all-steel construction that’s computer cut for precision and strength. The black powder coat finish adds durability and corrosion resistance, giving you confidence that it will hold up through years of towing. The sturdy build spreads towing forces evenly through the frame so you get dependable performance mile after mile.

Quick Disconnect Setup: Compatible with Roadmaster Tow Bars

Connecting to your tow bar is simple and secure. This kit works with Roadmaster tow bars when used with a quick-disconnect crossbar (910021-00 – sold separately). The square drawbars mount and remove quickly, locking in place with hitch pins so you can hook up or unhook without fuss.

DIY-Friendly Install: Bolt-On Design with Included Hardware

You don’t need welding or fabrication to get this installed. The brackets bolt directly to the vehicle frame for a custom fit. Instructions and mounting hardware come in the box, making it a straightforward job for anyone comfortable turning wrenches. Once bolted up, you’ve got a solid connection that’s ready for serious towing duty.

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

I’m very handy with tools so drilling the four holes required was a simple task. Everything fit as advertised and the quality was on point. Since I already owned a roadmaster tow bar this kit was a no brainer. My vehicle is 2017 Silverado so it was slightly different teardown of the front end. Thankfully i found a u tube video



by:

The installation took me about 7 hours, the facia removal was tedious , between the installation videos and instructions, I performed the task. This bar has one con, the pull rings on the removal bars are flimsy , my first pull stretched one out. I’m sure trailer has a fix for this under warranty, I hope.



by:

Etrailer was very easy to do business with and made it simple to ship my order directly to the RV shop that was going to install it. This was my first order from them, but I will definitely consider future purchases from them if I'm in need of something for my RV.



by:

The representative (Sarah) was very helpful and knowledgeable, the prices are very reasonable and all my items arrived on time. When I called with a question, she was very polite, friendly and genuinely sounded like she enjoyed her job. When I discovered one of the items I ordered wasn’t needed, getting help to return was hassle free. I would recommend etrailer to anyone that needs anything RV or trailer related. I will definitely do business with them again. I am impressed.



by:

We towed our 2004 Subaru Impreza WRX STI 3000 miles last year, this is an ideal setup, discreet when not in use, solid, and easy to get on/off. Very please with the support I received from Roadmaster as one of the bolt was missing, was sent super quickly.



by:

Not an easy install on a Trax but it is very well made and gives a clean look. I did customize by cutting down the 6 pin bracket supports to get it flush with front of the car.



by:

Awesome delivery speed, and a well made base plate for my 2007 Element. Installation was a breeze (thanks to my son’s heated shop) and I had to do no cutting to make this fit. I had a Stowmaster tow bar that came with my RV and etrailer was able to steer me to the correct missing parts to make this a really affordable installation. Now to get out of this snow!



by:

Purchased for a 1997 Subaru Impreza. Delivery was amazingly fast! I didn't have it installed until a few months later, as my travel plans had stalled. It didn't quite bolt right on, but was close, and a friend had to modify it some to make it work. I still hear a grating noise when I turn too sharp on one side, but otherwise it's fine.
The front connection plates didn't line up with the holes, so had to have those modified, as well, in order to line up and attach to the tow bar. Once the new holes were drilled, I was able to hook up and go.
It's relatively easy to connect after finding a way to do it alone.
I've towed from CO to TX and all over TX with it with no problems.



by:

After ordering the wrong crossbar, etrailer sent the correct one for our Mini Cooper quickly. However I did have to modify most of the holes as the cross bar didn’t quite fit (but close). I had to drill the three main bolt holes to 11/16 so that the bar would go over the Mini’s 3 main bumper bolts on both sides. The two lower bolt holes (each side), needed to be drilled out 3 sizes larger to accommodate the 4 bolts that come with the kit. I had to drill out the Minis lower holes to better align with the crossbars lower holes. I would also like to note it being a pain in the knuckles to reach one of the three (each side) bolts to put the stock nuts on the bolt and then try and get them tight. (The main bolt pattern for the upper bumper is diamond shape, one up tow bolts lower. (The lower “inside” bolt on each side is the one that is hard to get to and tighten.) Sorry I didn’t get picks, I was in a rush to get the car back together. There’s an angle piece on the cross bar that blocks the hard to reach bolt, it would be helpful if that could be made more accessible to reach.



by:

I’ve been purchasing products from ETrailer since 2005 and all the products I’ve purchased have been a great value. The products mentioned above installed perfectly and with the direct assistance from ETrailer everything fit as suggested. I will always interact with ETrailer as needs present themselves.



by:

Replaced same part that was damaged in a crash. I had used my original one for close to ten years without issue. Fast shipping from etrailer.



by:

The Base plate kit is well made and came with all the necessary hardware.Installation is relatively straight forward. I did have to enlarge two of the holes that didn't quite line up. But overall I'd recommend it.



by:

Bolted right up. Installation should be done with bumper on, as you can't fit the ends through the louvers without some convincing. Works great so far. Was able to use a Stowmaster 5000 with it.



by:

Installation was a bit trying. Ended up looking very clean and almost invisible.
Using the tow bar worked super easy and our motorhome hardly noticed the Mini Cooper back there.



by:

Came quickly and is very high quality. Great directions/video from road master makes the installation step by step easy to follow.
Skill level is probably at the intermediate level depending on experience.



by:

The #118-3 is a perfect fit on my 1995 Geo Tracker. When you pull off the removable arms you would never know they are there. The Quality is very good easy to put on all you have to do is drill 4 holes the tube on the base plate fits into the tube on the frame of the tracker and with the 2 bolts it is a solid fit. I was worried about the plate nut getting it inside of the frame but it went in easy when you put it over the frame tube and use a thin piece of metal to slide it in place. I’m very happy with it. I probably could of got it on without taking my bumper off but with only 4 bolts holding my bumper on it made it easier



by:

I could not get bolts on vehicle off to attach this.

Was returned for an alternate model that attached differently.



by:

Works great !

It has worked out great and have been using it regularly



by:

Product was as described and was easy to install. Will buy from etrailer again.



by:

Works as advertised, installation instructions could have have better diagrams, Took a while to figure out correct position.



by:

Had my local favorite mechanic install these and since it was the first time for him, took a little extra time (and he had to buy the special drill bit), but they work fine and fit the crossbar just fine.



by:

Great product, I've purchased other products and baseplates thru the years from you and have had no problems with install or with the products.



by:

I purchased the Roadmaster Base Plate for our 06 Saturn Vue. The base plate fit exactly as described. Was not to hard to install. I did my self to save money. The hardest part of the job was the removal of the front air dam and cutting out the access holes for the bars, Still not to bad if you have mechanical skills. The staff at e-trailer was very helpful and answered any questions that I had. It was delivered very quickly as stated and arrived on time. If you are considering this type of project I would highly recommend e-trailer.

  • Recommended Equipment for Flat Towing 2007 Saturn Vue Behind a Motorhome
    According to my research, the 2007 Saturn Vue is capable of being flat towed without modification, but I'd urge you to confirm that for yourself. From what I've read, it's not recommended to tow the vehicle above 65 mph, and there are specific steps mentioned in the owner's manual that need to be followed exactly. To flat tow the vehicle, you'll need a tow bar, base plates, safety cables, a wiring solution so the Vue's taillights work in tandem with those of the RV and a supplemental braking...

    In order to flat-tow a 2007 Saturn Vue with all four wheels on the ground behind a motor home you are going to need a tow bar, base plate kit, safety cables, tail light wiring harness, supplemental braking system, and possibly a high-low adapter. There may also be a few other smaller components that are needed depending on options the vehicle is equipped with. For a tow bar, I recommend the Roadmaster Falcon 2 Tow Bar part # RM-520.

  • Parts Needed to Flat Tow a 2005 Saturn Vue Behind an RV
    If your 2005 Satrun Vue is front wheel drive with a 4T45E transmission, then you will be able to flat tow it using a tow bar. If it has a VT25-E or MDRA transmission, you will need a car trailer to tow the vehicle. To determine which transmission you have, you can have a local dealership run the VIN number. If you determine that you can flat tow the vehicle, you will first need base plates. For a 4-cylinder engine model, use XL Base Plates, # 3111-1. For a 6-cylinder that is NOT a Redline...

    To flat tow your 2005 Saturn Vue you'll need a tow bar, base plates, wiring, and likely a high-low adapter.

  • Will the Roadmaster Base Plate Kit # 3121-1 Fit the Falcon All Terrain Tow Bar on a 2004 Saturn Vue
    Both base plate kits for the 2004 Saturn Vue are the XL style.
