I was trusting the video that is on E trailer site to walk me through how to install the roadmaster tow bar. It was exactly right on and I took the front end off of my toad, and prepped everything according to the directions on the first day. when my package arrived from E trailer the next day everything was in really great shape after shipping and I installed it the next day in about four hours time.

Review from a similar EZ in Base Plates


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.

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.

Review from a similar EZ in Base Plates


The product fit correctly. The product works great. The staff at etrailer almost lost the sale because the first person I spoke with said that I couldn't flat tow my 2007 Ford Focus. Luckily I am smarter than that guy was and did my own research. the customer relations part is why the rating is average. Check the parts and numbers yourself they may actually have what you need and they just can't figure it out.


Comments
I just wanted to give you a heads up that if your 2007 Ford Focus has an automatic transmission then it is suggested to use a tow dolly. If you have a manual transmission, then it can be flat towed. This comes from the manual from Focus. I just wanted to let you know so that your vehicle does not sustain damage.

Review from a similar EZ in Base Plates


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

Larry, Im assuming that youve towed your vehicle by now. Are you still happy with your choice and did you purchase any additional components like the electrical kit, fuse switch..etc Dave R

Have been using this tow adapter now for a while and everything works out fine, Easy to connect. I did purchase the Wiring harness from the tail lights to the front of the car instead of making it as I usually do and the connection to the RV from that connection and glad I did, the wiring harness also went easy and very fast.

Review from a similar EZ in Base Plates


A little more cutting on the plastic pieces under the car than I expected but not too difficult. The customer service was excellent. There was going to be a delay on the ship date. I however had to have the hitch for my job and could not wait. They jumped through whatever hoops they had to and got it to me the next day. Thank you etrailer.com in a world where customer service seems to be disappearing you really excelled

Review from a similar EZ in Base Plates


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.

Base plate was a good fit for make/model of vehicle. We only had difficulty because part of the frame on the vehicle was bent requiring some tweaking on our part, but it would have fit fine if hadn't been for that

Review from a similar EZ in Base Plates


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)

Review from a similar EZ in Base Plates


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.

Review from a similar EZ in Base Plates


Installed on 2005 mini cooper convertible. Choose this base plate for our mini since it provided highest attachment height for tow bar (12 inches off ground, only requires 3 inch drop from back of RV), and attaches to mini frame more substantially that blue ox. Installation directions are nearly perfect, we had to widen holes on passenger side to line up with frame. Modification was approved by Roadmaster.

Review from a similar EZ in Base Plates


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.

Review from a similar EZ in Base Plates


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.


Comments
I have towed my Terrain about 3500 miles with no issues. It tows and tracks extremely well. I put red paint marks on the bolts that are easily seen, so that I can see at a glance if any bolts have loosened up. I use a Roadmaster All Terrain tow hitch and SMI Duo braking system.

  • What Type of Crossbar Does Roadmaster Base Plate Kit part # 521558-1 Need to be Used With
    The Roadmaster base plate kit part # 521558-1 is designed to be used with a Roadmaster tow bar that has a crossbar. But you don't have to order the crossbars separately. The correct crossbar that you'd need would come with the tow bar. So you'd just need to order a tow bar that has a crossbar like the Roadmaster Falcon 2 part # RM-520 and you'd be set.

  • Base Plates and Accessories for 2008 Honda Fit Sport
    According to my contact at Roadmaster, the # 521558 base plate kit will indeed fit all models of the 2008 Honda Fit, including the Sport model. In my research, I found that the Fit is capable of being flat towed without modification, but you will want to consult the owners manual and follow the recommendations listed under the Recreational Towing section. You will also need a tow bar, safety cables, a lighting solution and a supplemental braking system to flat tow your Fit. The Roadmaster...

    Yes, your 2007 Honda Fit Sport with a manual transmission can be flat towed behind an RV. You'd need to start with a base plate kit like the part # 521558-1 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 best supplemental braking system for your situation is the Blue Ox Patriot 3 part # BRK2019 which is a portable braking system.
