Today we're going to be taking a look at the Roadmaster base plate to a Blue Ox and Demco tow bar adapter. This adapter allows you to use your Roadmaster base plates with a variety of tow bars. It's going to work with RV mounted Blue Ox tow bars like the Adventurer, Allure, Ambassador, Alpha, Aventa, Aventa II, Aventa LX, Carbar, Aladdin, Alexa, and Acclaim. It's going to work with A-Frame Blue Ox tow bars with one or three-pronged attachments, and a few Demco tow bars like the Illuminator, Commander, Excalibur, Quick Tow, and Dominator. This adapter right here simply bolts to the mounting bracket. It bolts to the Roadmaster base plates. Mounting hardware to get this adapter installed, all that's included.

If you plan to use any Roadmaster brackets with removable front arms, you will need quick disconnects in addition to the adapter. This does not fit Roadmaster EZ-5 MX or MS series brackets. Your installation holes are located right here, pre-drilled. Again, hardware included. The parts made in the USA.

It's constructed of a very durable sturdy steel construction. It's going to feature a black powder coated finish on it, which is going to do a great job at resisting rust and corrosion and lasting a long time. It does come with the pins and clips right here at the attachment points. A few measurements to go over with you real quick. The overall length that it offers edge to edge is going to measure 32 inches. This is a simple 2 inch by 2 inch angle iron.

2 inch deep. 2 inch tall. From the center of the inner hole to the same one on the other side or same point on the other side, center on center, the inner holes are separated on center by 27 inches. Outer wholes are separated on center by 30 inches. That's going to do it for today's look at the Roadmaster base plate to Blue Ox and Demco tow bar adapter..

Very easy to install and looks great after installation


I had to convert from Roadmaster to Blue Ox. The part was exact. Delivered on time. You guys have done a lot of planning with carriers. Now I can tow my car with my RV. Thank you.


Now both my 2018 Jeep Cherokee and my Miata are set up to tow. etrailer has been sup in answering any questions I had to make sure I got the correct parts. Kevin D worked with me and was great. Everything is installed and ready for my next trip. The web site is super-easy to find what you need and the prices are great, with very fast shipping.


Shipping was fast. Only problem was some paint flaked off of the base plate before being installed. It's going to get dinged anyway so, touch up paint is expected.


looks like it will bolt right quite sim ply


This adapter bar matches perfect from the Roadmaster tow brackets to the Blue Ox tow bar from the RV. I use this adapter on two different vehicle makes we flat tow.


Product looks robust, easy to install. One thing, cannot remove arms with adapter attached. Have to uninstall so arms are loose. This does not allow thread locker. probably the quick unit, (more money), would be more practical. Will work around it.


I've purchased from etrailer for many years. They are always great and this was no exception. After a little confusion with one rep I worked with another and have just received all I need for a new flat-tow package for my RV/Jeep. Meghan was able to help me figure out how to use my existing tow bar with an adapter, which saved me a good bit. I highly recommend etrailer!!!!



Products continue to work great. No complaints.


This adapter fit perfectly and allows me to use my Blue Ox Acclaim tow bar with a Roadmaster base plate. Thanx to all the good folks at etrailer for all their help..

I work for a Drive-Away service and do a lot of towing behind a varied assortment of tow vehicles..The items mentioned in this Email have been performing flawlessly since I purchased them. When several of us go on a big job, I am hooked up and ready to roll while they are still struggling with magnetic lights etc. The job is so much simpler when it is done right.


well constructed . very pleased with this product. as always e-trailer #1


I had Blue Ox tow system bought a vehicle that had Roadmaster plates bought a Roadmaster adapter to my Blue Ox tow bar to make it work on the vehicle everything worked out perfect as a matter of fact the sales agent had sold me a part that I did not need I was able to call and send it back for a full refund on that part that was not necessary very grateful very easy to do business with prompt on time and save me a lot of money from having to exchange everything over from Blue Ox to Roadmaster very satisfied customer


I am preparing to tow my 1993 Miata behind a motorhome. After some research I decided to rely on Roadmaster products because they manufactured base plates for the Miata. Initially I purchased a Roadmaster Tracker bar that uses a 2 inch ball to connect. Later I encountered a Blux Ox Aventa on Craigslist that I felt would be better because it has a receiver connection that cannot work lose on rough roads. To make that work I had to purchase the RM-033 adapter bar.

In retrospect I recommend the Roadmaster Falcon tow bar to avoid about $100 of adapters that I needed to make my current system operate. My first towing experience so lots of rookie errors at my expense. BTW, even with my very light Miata, using the Roadmaster LX base plates, the Falcon tow bar, safety cables and tow lights, the setup costs about $1000 and some states require a supplementary brake system that is really pricy. Love my 1993 Miata, which is probably now worth about a $1000, so I hope it appreciates all I am doing to tow it along on my trips.

E-trailer has provided excellent service for this and an earlier order for the Tracker tow bar. With the free shipping, the pricing is very fair.


Well built and fits perfectly. Quality product I expect to last a long time.


super easy to change from road master to blue ox bolted right on worked great


Instructions were very good for the installation on my 2010 Honda CRV for both the baseplate and the blue ox adapter. Fit and finish were good. Product arrived as promised. Minimal tools were needed, but installation with the vehicle on the garage concrete floor was probably a little more tedious than that on a lift. I would say that you do need some mechanical talents to do this on your own. It was worth the monetary savings for me to install these products.


Adam and the folks at etrailer were excellent. The fast shipping was notable; which I believe that Adam made it happen, (he is a professional, indeed). Thanks alot



Just fine. I installed it and forgot it. However I do recommend using the same brand Roadmaster tow bar with this base plate not the Blue Ox tow bar! Believe it or not + I have found a flaw with the Blue Ox.


Ordered additional items for tow bar mounts. Carmel was very helpful. I couldn't figure out which items I need to go from Roadmaster to Blue Ox. She give me the part numbers after searching their data base and ordered what I needed. Order was sent right out and I received the items three days later.


This adapter fit my blue ox tow bar perfectly. I don't know about it's overall performance strength wise until I put a few thousand miles on it.


Cathy was very helpful in finding the best product for my need. She took the time to go through all the possible tow bar adapters and find the one that worked best to tow my custom steel bumper Suzuki with the Dominator tow bar. I also saved 50% off the cost from the OEM price! I will definitely use etrailer again!


Excellent service, communication shipping, and fit to my application on my 2004 Jeep TJ Rubicon. Roadster base plate to a Demco towbar.


Everything so far I have purchased has performed perfectly but even better has been the customer service which has been exemplary. Every question I have had has been answered in a timely and knowledgeable way. Thank you.


So easy to put on.
It took longer to
open the box.
Less than 10 min to install.
Kelly was helpful on phone and had product shipped same day.


Every part from those E trailer folks is perfect


Fast friendly service. Good price's.


My Adapter arrived on time just as promised. Great Customer Service.
