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.

Great people to deal with. Order rec'd sooner than expected and the Roadmaster equipment was excellent.

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.



by:

The instructions were very good, the video was excellent. If I could make a recommendation, it was a little lacking at the end. Since the Smart car is virtually held together with push pins a little more time spent putting the car back together wourl have been helpful. I'm all done and I have 2 push pins left over and don't know where they go.



by:

After 1 year of full-time use I am very happy with the base kit. It was relatively easy to install with the aid of a car lift. I would imagine that it would be a little harder without.

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

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.



by:

Installation is a bit involved but worth every second of it for the peace of mind while driving. Had a slight issue with my ordering incorrect parts but these guys went above and beyond to get it resolved in time to not miss my trip. Even rush manufactured them due to not being in stock!! Great company to do business with.



by:

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.



by:

Great product.
Excellent fit.
Everything
has performed wonderfully.



by:

Product is great, packaging was rough, the parts were banging into each other inside the box. Box looked like it either had been opened before or had sat in a warehouse for several years.



by:

Parts came very quickly. The base plates are really well make and of heavy material. If you watch the video it is a breeze to install. Make sure you have some new clips for your bumper as the old ones will break, not all but some. I ordered clips from Amazon. I used a vibrating saw with cutting blade and it did nice job cutting plastic bumper cover.



by:

This system worked perfectly from experience. They help from trailers e trailer agents was crucial for guiding me through the process.



by:

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.



by:

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.



by:

It is a lot easier to take of the bumper it is all plastic anyway then to take off the air intake

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 well...no choice I guess.



by:

Service was immediate. Delivered on time. Tracking was exact. My opinion, overall outstanding.



by:

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!



by:

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.



by:

Very happy with this product. Installation was pretty easy. I see no reason to pay someone to install this. True you have to take the bumper off and a large metal support beam but it was pretty easy. You just have to take it slow and not get frustrated. The bumper on the Honda Fit is held on with a gazillion little plastic clips and snap joints. Everything fits tight on a Honda so you have to be patient. My only complaint is they don't give you the exact torque settings. I had to consult a shop manual to get the correct torque values. They give a table at the end of the instructions that gives common torque values for various bolt sizes. I thought that was lame they could have given the correct value from the shop manual. Certainly not enough to lower my rating. This bar is awesome and when the drawbars are removed the base plate is almost completely hidden. My wife wanted nothing to show on the front of the car. She was very pleased with it.

In the picture attached the bar is almost completely hidden. All you see are two small black circles. It takes about 2 seconds to mount the drawbars, just twist and go. VERY sturdy. I tow my Honda behind the motorhome with confidence.



by:

Customer service is very helpful and patient as they walked through everything I needed to set up a car to be towed behind my motorhome.



by:

The Roadmaster base Plate kit does what it was designed to do. A difficult install as the Smart ForTwo did not lend itself to an easy base plate engineering design.
Installed it myself though with help from the instructions and etrailer on line instructions. I like the finished base plate. It is barely visible protruding only slightly from the black lower radiator grill (see photo)



by:

Very good product at a great price. Instructions and video are for a 2013 terrain and things were a bit different on my 2015. When all screws and clips are removed the front piece cannot be just pulled forward. There is a rear facing clip and you have to pull to the side to remove from this piece. (pics attached)There was no PS cooler attached in front on mine. Remove washer bottle totally which consists of 2 nuts and 1 bolt otherwise you will never get back up plate for top brackets in. If you remove horns it also makes installing the top brackets much easier.



by:

These work great on my suzuki sx4.



by:

The installation on this was surprisingly quick on my 2011 Fit (base/non-sport version). Everything fit well (no pun intended).

A few minor changes over the video as my car was slightly different:
- I didn't have to trim anything on the air dam -- the tubes lined up perfectly with the slots on my grill.
- There was a in the wheel on each side where the plastic bumper meets the steel body panel. I didn't realize they were there (they're hidden somewhat) so I ended up cracking the hole this screw was in, but everything came back together nice and tight anyway.

  • Can 2008 Dodge Grand Caravan Flat Tow 2011 Hyundai Sonata
    I looked up the towing capacity of your 2008 Dodge Grand Caravan and it appears to have a 3,600 lb capacity. The weight of your 2011 Hyundai Sonata ranges 3,161 to 3,452 lbs so you should be fine. To flat tow the Sonata you'll need a basse plate kit like part # 521631-1. 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 2, # RM-520. For safety...

  • Can 2011 Hyundai Sonata be Flat Towed behind RV
    If your 2011 Hyundai Sonata has a manual transmission you can flat tow it with all 4 wheels on the ground but if you have an automatic transmission you'd have to use a tow dolly like the part # RM-2050-1. If you have a manual transmission the base plate kit you'd want is the part # 521631-1 which is a confirmed 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...
