The drawbars, or front arms, on the EZ series base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. 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.

Overall good product. Installation was not difficult. Replacement "skid plate" is a bit thin for my liking but if your not doing any rock crawling it will be fine.;)


Easy to install for the do it yourselfer. Good quality and fit. etrailer customer service was great too.



Still working great!


Great fit and fore thought in placement of light and breakaway mounts. A great product from a fine company. By the way I personally installed by myself!


Quality base plate. I since sold my motorhome and am no longer towing.


Tow bar system works as planned.


quick and timely delivery, great web site with tutorial videos. Installed relatively easy. I was able to do it in my driveway with basic hand tools.

It has been working perfectly on the 2012 jeep liberty. In fact, the baseplate I used on my previous vehicle jeep grand cherokee was more difficult to connect and disconnect than this new style push in and rotate to lock into place. For whatever reasons this new style baseplate is faster connect and faster disconnect than the previous style.


Product was perfect, installed easily....still using today one year later....thanks to all the staff

I wanted to see if you had more to say on your review? I would be happy to help.


Performed as advertised good product.


Prepared my vehicle for the base plate. The base plate has a manufacturing defect in that the crossbar is approximately.375 inches short. The hole pattern matched on one side but the other side would not line up with the vehicle holes. The mounting plate overlapped the mounting holes by 1/3rd. Clearly, the assembly was short. I find my disassembled vehicle sitting for a week waiting for the replacement to arrive. Hopefully, Roadmaster QC did a better job on the new base plate assembly that I am waiting for.


This reasonably priced base plate kit was professionally installed on a coupe that was pulled around the New England states for two months. The kit and the car made it possible to see many sites along the route that would have been bypassed without the toad. The kit is solid and provides secure tow-ability.


Installed myself with a help of a friend it’s easier with two people took about 31/2 hours instruction were a little off. my car was an SS which was a little differentt so you had to figure a couple things out
Make sure you order the fish cables to help you pull bolts through


I received the base plate for my Miata at 4:30 Monday by 7:00 it was installed and ready to go.A great product fit very nicely.Ordering and follow up went great can’t wait to try it out Just need to decide on the tow bar we will use.The Falcon or Sterling .Thank you for a great product and service.


2007 MX5
The build quality was good....welds
were well done....paint was good
Instructions were pretty thorough.
Lots of trimming away of the splash shield for this install!!
Oh choice I guess.


Very heavy duty. Much more than needed for my application but better more than less.
Heavy duty also means heavy in weight. Not easy to lift and move.


I was having problems with the bracket that was on the car when I bought it and when it no longer felt safe to me, I looked on your website for a replacement. Lo and behold, this product appeared to be better designed and an easier installation. Putting 8t on today proved that. I am very happy with the product and your service. Thank you very much!


my baseplate was delivered on time and in great shape.


Purchased the towing adapter for my GMC Terrain a few week ago, received it on time & boxed not damaged. Watched the videos’ about three time on how to do it myself and started one evening and finished it the next morning about three hours with Beer Breaks, LoL. All the parts fix perfectly, had no problems with any of the parts, Product is real sturdy and if you don’t know where to look at the bumper you will not see the hide away receiver brackets. Very nice product, do it yourself and save
Up loading two photos if it will let me one is with hide away brackets installed and the other one you can see is my complete tow bar attached to the hide away brackets


Great installation instructions and video. Was an interesting and fun project installing in our Mini-Cooper


Roadmaster base plate for 2010 GMC Terrain. Very detailed instructions, great videos. Product was as described, no holes to drill, just replace factory parts with Roadmaster parts. Everything went together very well. I used the instructions supplied along with the video on my laptop. Hardest part was popping the bumper shroud back on due to colder temperature. I have a fair bit of experience with rebuilding classic cars so have lots tools and reasonable mechanical ability.


Installed on 2014 GMC Acadia. Very sturdy and heavy duty base plate. I installed it myself. You will need a little automotive knowledge and more tools then the average do it yourself-er. It took about 6 hours, by myself. It looks more intimidating then it turned out to be. You can't see it when not in use which makes it nice for the wife, since it's her car.
Pictures show the tow bar adapter. Sorry, no pictures of adapter removed.


Great customer service, fair price for a quality product. Would use etrailer again and recommend them if you are considering one of their products.


Have had no problems with this base plate fit my smart car perfectly q. Would recommend to all

Whoever designed this base plate has probably never seen a Saturn car let alone taken one apart to install the base plate. The instructions has one picture, that doesn't show how any of it is supposed to fit on the vehicle and it implies that you only need to remove the bumper to install. After hours of fumbling with the base plate, I ended up having to remove the bumper cover, bumper, headlights, headlight brackets, and fenders. On top of that, I had to drill four 3/4" holes.

  • Roadmaster Base Plates for a Sterling Tow Bar and a 2011 Jeep Liberty
    The first thing you are going to want to do is consult the owners manual of your 2011 Jeep Liberty to determine if it can be flat towed or if anything additional is needed to tow the vehicle. From the research I did, all wheel drive models with automatic transmissions and models with 2 wheel drive and a 6 or 5 speed can only be towed on a trailer. Two wheel drive models with automatic transmission will require a transmission lube pump. And 4 wheel drive models with automatic transmission...

  • Roadmaster Battery Charge Line Kit for Towed Vehicles and for Motorhomes
    Yes the Roadmaster Battery Charge Line Kit for Towed Vehicles, # RM-156-25 is minimal cost and while not "needed" for many applications it is a good item to add as it maintains the battery charge in your towed vehicle while the car is being towed. However, this does require that the RV's plug have a charge line pin that is "hot" to provide that power from the plug connection to the towed. Most/many motorhomes come from the factory with this pin already wired. If your motorhome is then...

  • Recommended Parts To Flat-Tow a 2012 Jeep Liberty
    In regards to flat-towing components, there are a few different brands such as Roadmaster, Blue Ox, or Demco to choose from. If you prefer one over another then that is fine but I think each excel in certain areas so I recommend mixing and matching. The Roadmaster tow bars for example have a torque multiplier system that makes disengaging the arms much easier than other options such as Blue Ox. The Demco braking systems tend to be easier to install and perform better than other options...
