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.

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.

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!!!!

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.

by: BillyT 12/16/2020

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.

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.

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.

by: Steve N 04/07/2015

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!

by: Dana 10/11/2022

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.

by: Donl 10/31/2016

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.

by: Stephen 03/16/2019

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.

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

by: Carl 02/26/2023

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.

Parts Needed to Flat Tow a 2005 Jeep Wrangler with a 2014 Silverado 1500
If you already have Roadmaster base plates installed on your 2005 Jeep Wrangler then the RoadMaster Base Plate to Blue Ox and Demco Tow Bars Adapter # RM-033 and the Blue Ox Alpha Tow Bar # BX7380 are a great selection. If you don't already have a base plate kit installed then you will need to choose one from the linked selection as they are bumper specific. If you are unsure what you have just send me a photo and I can identify what you have. Since the Blue Ox Alpha comes with safety...

What Base Plate Can I Use with My Blue Ox Acclaim or Adventurer Towbar on My 2022 Jeep Wrangler?
I have a great base plate solution for you. Since you say that your Blue Ox tow bar has a 5k capacity, I believe you are referring to either the Blue Ox Adventurer Tow Bar - Car Mount - 2" Ball # BX7322 or the Blue Ox Acclaim # BX4330. Unfortunately, we do not currently carry an etrailer baseplate that can be used with either of these models. However, we have a great Roadmaster base plate and adapter that will allow you to use your tow bars on your 2022 Jeep Wrangler. For that setup, I...

Parts Needed to Flat Tow a 2020 Buick Envision
I can definitely help you out with a flat towing setup for your 2020 Buick Envision! You can definitely use the Roadmaster Crossbar-Style Base Plate Kit # 523196-4 with the Adapter # RM-033 so that the base plate kit is compatible with a Blue Ox tow bar, but in all honesty it would be much easier to use the Roadmaster Direct-Connect Base Plate Kit # RM-523196-5 with the Adapter Kit # BX88185 instead because you don't have a whole bar that you need to use as an adapter.

If you're looking to complete your flat towing setup you're going to need: - A braking system, like the Blue Ox Patriot Portable Flat Tow Brake System # BLU37TR with the Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400, & - A wiring harness, like...

Is a Blue Ox Tow Bar Compatible w/ Roadmaster Crossbar-Style Base Plate?
Hey Esther. The Crossbar for Roadmaster Motorhome Mounted Tow Bars item # RM-067 is not compatible with Blue Ox tow bars.

It sounds like you have the Roadmaster Crossbar-Style Base Plate Kit item # RM-523193-4 installed on your 2018 Chev Equinox.

Does The Roadmaster Base Plate Adapter RM-033 Have A Weight Rating
The RoadMaster Base Plate to Blue Ox and Demco Tow Bars Adapter part # RM-033 does not have a weight rating. The weight rating would be determined by the tow bar that you use the adapter with. For example the Blue Ox Acclaim Tow Bar part # BX4330 is rated for 5,000 lbs.

Can Blue Ox Aventa LV Tow Bar be Used With 2019 Mini Cooper S Convertible & Roadmaster Base Plates
Yes you can use your Blue Ox Aventa LX tow bar BX7445 to flat tow your 2019 Mini Cooper S Convertible. I recommend the Blue Ox Base Plate Kit # BX1312, however - so long as your Mini does NOT have the R57 LCI with 1.6 engine - you can use the Roadmaster Crossbar-Style Base Plate Kit # RM-521882-4. The adapter you need to use your tow bar with this kit is the RoadMaster Base Plate to Blue Ox and Demco Tow Bars Adapter # RM-033. The wiring kit you need for your 2019 Mini Cooper S Convertible...

Since you already have safety cables and a high low adapter that leaves wiring and a brake system.

Hello Mark; the Roadmaster Crossbar-Style Base Plate Adapter for Blue Ox and Demco Tow Bars # RM-033 is compatible with the Blue Ox Acclaim Non-Binding Tow Bar # BX4330. Which base plate kit do you have? This adapter is designed for the Standard (no MX or MS series brackets) crossbar-style base plate. If you have the # RM-521453-4 or # RM84VR (521456-4) on your 2021 Wrangler you need the # RM-032 instead.

Hey Warren, yes a Blue Ox tow bar can connect to a Roadmaster EZ base plate kit like the part # 523149-1 that fits your 2015 Buick Enclave but you do need to use the correct adapter since it's two different brands. For that you'd want the part # RM-033.

Recommended Towing Method For A 2019 Mitsubishi Mirage
The thing with tow bars is that they are not vehicle specific but rather base plate specific.

Can 1984 VW Vanagon be Flat Towed
According to my research, a manual transmission equipped Vanagon can be flat towed with no worries. Simply leave the transmission in neutral, and off you go. Automatic transmission equipped 2WD models need to be trailered, but whether or non syncro (4WD) vehicles could be flat towed wasn't clear. I found this information through a Google search, but I'd urge you to confirm for yourself. To flat tow your Vanagon, you'd need base plates, a tow bar, a wiring solution and a supplemental braking...

there are 5 thing needed when you are flat-towing a vehicle. You will need base plates, a tow bar, safety cables, lighting for the towed vehicle, and most states now require a supplemental brake system. If you like the Blue Ox Adventurer Tow Bar, part # BX7322, I recommend using Blue Ox base plates as well, like part # BX2238. This eliminates the hassle of using an adapter that allows you to be able to use different manufacturers for base plates and tow bars. You mentioned the RoadMaster...

Parts Needed to Flat Tow a 2002 Toyota MR2 Spyder Behind and RV
I double-checked with Roadmaster and base plates # 1169-1 are indeed the correct base plates for your 2002 Toyota MR2 Spyder. They are actually listed for 2000 to 2003 models. On the 2000 to 2002 models you will need to remove the grill for installation. For a compatible tow bar I recommend the Falcon 2, # RM-520. It is rated for 6,000 pounds so it can handle the MR2 with ease. You will also need safety cables # RM-643. For lighting I recommend a simple magnetic kit # RM-2120 because...

You can use either of the Roadmaster tow bar adapters to connect your Alexxa BX7435 tow bar to the Roadmaster XL Base Plates # 199-5. If you choose the # RM-033 adapter you will also need the Roadmaster Tow Bar Quick Disconnect Kit, item # RM-201, which will allow the tow bar to be easily disconnected. If you choose the # RM-032 adapter you will not need the addition of the quick disconnects and one side of the adapter bar will stay attached to the Blue Ox tow bar when disconnected.
