Features to know about
Made for a Clean Front End: Hidden Bracket Design with Removable Arms
When you’re not towing, this setup keeps things looking clean. Once the drawbars are removed, the remaining brackets are virtually invisible and sit tucked within the grille, protected from scrapes and scuffs. The partially hidden design preserves the vehicle’s factory appearance while keeping the mounting points ready whenever you need to tow again.
Quick to Hook Up: Twist-Lock Arms with No Pins or Clips
Getting on the road is easier with the twist-lock drawbars. Just insert the arms into the brackets, twist to lock, and you’re ready to connect your tow bar—no pins or clips required. When it’s time to unhook, twist and pull them out just as easily. It’s a simple motion that makes setup and disconnecting faster and less hassle, even when you’re doing it alone.
Solid Build You Can Trust: Computer-Cut, All-Steel Construction
This base plate kit is built for strength and precision. The all-steel construction is computer-cut for an exact fit and coated in a black powder finish that resists corrosion. The design bolts directly to the frame, spreading towing forces evenly so it feels solid mile after mile without welding or fabrication required.
Seamless Fit for Your Setup: Compatible with Roadmaster Tow Bars
No need to overhaul your towing gear—the kit works directly with Roadmaster tow bars when used with the quick-disconnect crossbar part #910021-00 (sold separately). It’s designed so everything lines up right out of the box, and each kit comes with clear instructions and all mounting hardware included for a straightforward install.

installation instructions were clear and very helpful, took me about 4 hours to install, would have been faster if i had attempted anything like this before.. removing front fascia and trimming the openings. Easy to use.

I rated this excellent based on all my previous orders with e-trailer, because they have been great over the years. Even when something goes wrong they always make it right in the end. My review of this product will wait until after the holidays because this is going to be a gift and I don't to re-box it. The item is very heavy and hopefully in good condition. There is a 4" to 6" gouge in the side of the box from shipping, but understandable given the weight.

Thank you for the fast delivery. I haven’t installed the base plate yet so I can’t rate the performance of it. From the looks of it, it should be an easy installation and is greatly engineered. I will be at ease when towing my Jeep.
The only negative thing is packaging. I know that this is a heavy item, but this box and inside padding was in pieces.

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.

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.

Thanks for the review and for sharing your installation experience Christian. Your tip about leaving the bumper on during install is really helpful, especially since fitting the ends through the louvers can take a little extra maneuvering. It’s also great to hear the setup works well with your Stowmaster 5000. The install looks great, and we appreciate you sharing the picture! Where did you go for the first trip?

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

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!

Overall the installation was great, however the process of drilling 3 - 1/2" holes in that little bumper that has a Rockwell Hardness of about 60, seems to be a bit over the top.The instructions are spot on, delivery was great, the quality of product was accurate. I am a happy boy!

Fit and finish is great, the illustration for what you trim on the bumper isn't great but otherwise pretty easy install (I ended up measuring between the mounts on the draw bar and just trimmed accordingly)

- Can 2015 Jeep Patriot Manual Transmission FWD be Flat TowedYes, you can flat tow a 2015 Jeep Patriot FWD with a manual/standard transmission. The Roadmaster base plate kit part # 521441-1 that you referenced is the correct fit. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon All Terain, # RM-522. This has non-binding arms which makes the setup very easy to connect/disconnect. For lighting/safety...
view full answer... - Is 2015 Jeep Patriot Capable of Being Flat TowedAccording to the 2015 Jeep Patriot Owner's Manual, automatic transmission equipped models of the Patriot aren't flat towable. If your Patriot is a FWD model, it can be towed with the front wheels off the ground using a tow dolly like # RM-2050-1. 4WD models would need to be towed on a trailer.

The only way to tow your Patriot if it has an automatic transmission is to use a dolly like item # DM9713093. For a compatible base plate kit, I recommend the Roadmaster Crossbar-Style Base Plate Kit item # 521441-1. This has removable arms and will work great with the etrailer SD Non-Binding Tow Bar item # e44ZR. This tow bar has a 6,000...
view full answer... - Parts Needed to Flat Tow a 2014 Jeep Patriot Behind a Motor HomeAccording to the owners manual for the 2014 Jeep Patriot in the recreational towing section, you can only flat tow the vehicle if it has a manual transmission. If it is an automatic it cannot be towed with all 4 wheels on the ground. It can be towed on a tow dolly, such as # RM-2050-1, with the front axle on the dolly. This only works for front wheel drive models and would work with manual or automatics. And of course, the third option is to tow the vehicle on a trailer with all 4 wheels...

The best wiring harness to flat tow your 2016 Jeep Patriot is going to be the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267. This kit splices a set of diodes into your taillight wiring so that your motorhome can activate them while you are towing your Jeep. This kit also includes the cord that will connect to your motorhome home's 7-way. I have linked an installation video so you can see how to get this wiring harness set up. The rest of the parts...
view full answer... - Which Base Plate Kit for 2017 Jeep Patriot Requires Least Amount of TrimmingThere isn't a whole lot of trimming for either the Roadmaster base plate kit part # 521441-1 or the Blue Ox part # BX1130 but the Roadmaster has the edge in my opinion as both require fascia trimming but the Blue Ox requires a reciprocating saw to trim a portion of the bumper beam.

- Recommended Parts to Flat Tow 2014 Jeep Patriot Behind MotorhomeIn order to flat tow your 2014 Jeep Patriot, you'll need a tow bar which you already have, base plates, a wiring setup, a supplemental braking system and possibly a high/low adapter. The Roadmaster # 521441-1 would be a fine choice for a base plate, as long as your Patriot isn't equipped with the tow hooks up front. If you do have the tow hooks, you'll need to go with the Blue Ox # BX1130 along with a # RM-031 adapter. If you don't already have the necessary safety cables, use # RM-643....

This is a crossbar style base plate kit which has removable arms that attach to the bar on the etrailer tow bar. You definitely need to use the bar.

It is true that these base plates are different based on height and width dimensions but they are both good options for your Jeep. The width or distance between the attachment points for a tow bar are different, but there is not a specific width that is too narrow or too wide for systems designed to work together. They will allow similar clearances...

The fog lights do not interfere with the installation of the Roadmaster base plates. I have attached a photo showing the base plates installed on a Jeep Patriot with fog lights.

- Economic Tow Bar Recommendation for 2016 Jeep Patriot with Roadmaster Base Plate KitThe most economic and safe way to tow a vehicle with a Roadmaster base plate kit like the part # 521441-1 that you referenced is going to be with a Roadmaster tow bar. Otherwise you have to get an adapter to go along with it which adds expense to the setup. For the price the Tracker part # RM-020 is the one to go with. But you would be happier with the Stowmaster part # RM-501 which has telescoping arms that allow you to relieve tension in the arms when you are connecting and disconnecting...

This kit is easy to maintain and there are a lot of good places to mount everything on your vehicle.
