Average Customer Rating:  4.8 out of 5 stars   (181 Customer Reviews)

Add a bike carrier or cargo carrier with the dual hitch receiver.

by:

Worked out great for my family bike adventure. Traveled with that setup over 1000 miles and it was easy drive. I had cargo carrier on the bottom and bike rack on top, and with that setup and 4 people on board still plenty of ground clearance 11". Dual hitch is a solid piece of steel that can carry a lot of lbs. Just don't overload max. tong weight, need some room for safety!

Solid piece of equipment. Heavy duty hitch, great for custom multi use, best if you have large Suv or pick up truck with biger ground clearance.



by:

piece seems incredibly well built. was delivered incredibly fast and free shipping for a 24 lb item. problem was square receiver was too high off ground for the e.bike wrack to be a comfortable height to lift or ramp the bike onto the hauler. the 6 inch drop made this much easier



by:

This adapter design was exactly what I was looking for. I often carry 4 or more bikes with my Sylvan GO. The pictures show how I configured my setup. Its perfect!!! And yes, I have to be a little careful on really tight turns but its never been an issue. Thank you George and the etrailer team.



by:

Great hitch. Exactly what it says in the description. Works perfect for my Blue ox tow bar and my 1UP bike rack.



by:

Works great. Easy to install. No assembly is required. Solved our problem of mounting our bike rack as well as our trailer.



by:

Very sturdy, and a great device for variable hitch heights!



by:

This seems sturdy and fits, but it is a slightly loose fitting. A better design would enable you to tighten the fit.

If you are having issues with it sitting tight, you could always use an anti-rattle hitch lock, like part # RM-061 to reduce the loose fit.



by:

I use this for towing my TOAD and flipped up using the upper one for my E-bike rack. After 1 year, this dual receiver has worked flawlessly and is very strong. I would recommend it to anyone who needs something along this line. Lastly using a hitch clamp / anti wobble device will take any play out the receiver.



by:

Good product. We have travelled over 10k miles towing a car and two electric bikes. No issues, no problems



by:

We bought this hitch along with a bike rack. After a year of use we are still travelling across North America. Awesome product! Easy and totally easy to use.

Delivery was fast and efficient.



by:

A very well built and sturdy hitch. Allows us to attach our flat tow car and bicycle rack on our motorhome.



by:

This is exactly what I needed to tow my Jeep Gladiator behind my class C



by:

Exactly what I needed to not only tow our Jeep, but also to put our Hollywood bike rack on. Great quality!



by:

This hitch adapter is just what I needed to carry bikes and flat tow my car. Etrailer is very helpful as carry what I need.



by:

It works great, it's what I need , Id like it better if it was cheaper.

Heavy duty, well made, and fits perfect.

High quality

Great product at a fair price . Customer rep was very helpful .

Great



by:

This is a great and heavy built hitch adapter. My only issue is that if given only 1/2 inch more distance between the two adapters it would help a lot. I cannot open up buy Blue Ox Towing bars out of the stow away position in the lower receiver while my 4 bike Thule bike carrier is installed on the upper reciever. Quite a nuisance. Otherwise, a GREAT product.



by:

Does it's job well. Holds the bike rack for the ebikes and allows us to tow our Jeep behind the RV.

  • Dual Hitch Adapter For Flat Towing And Carrying A Bike Rack
    Hello Steve. I do have a good solution for you, but I cannot recommend using the Malone Adapter # MPG544. Since it is rated for towing only 4,000 lbs, your 8,000 lb towed vehicle would be double the max towing capacity. You are right about there being very little tongue weight when flat towing, but I still cannot recommend using it. Instead, I suggest you use the Roadmaster Dual Hitch Receiver Adapter # RM-077-6. This is a dual hitch adapter that is essentially designed specifically for...

  • Recommended Dual Ball Mount to Tow a Trailer and Use a Bike Rack
    Thanks for the picture! To tow a trailer and haul a bike rack off of your Thor Magnitude's hitch, I recommend the Gen-Y Adjustable 2-Ball Mount w/ Stacked Receivers item # 325-GH-514. This adjustable ball mount has four 2" receiver openings that will allow you to use both a hitch mounted bike rack and tow your trailer. This ball mount has a 12,000 lbs towing capacity and a 1,500 lbs maximum tongue weight. This will not reduce your motorhome's current capacity. This ball mount includes...

  • Recommended Dual Hitch Adapter & Ebike Rack For Flat Towing
    There are dual hitch adapters you can use when flat towing so you can carry your ebikes, but none have an offset. The correct adapter is going to depend on the rise or drop you need: - 2-1/4" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-2 - 2" or 6" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-6 - 2" or 8" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-8 - 2" or 10" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-10 As for a bike rack...

  • Can Dual Hitch Adapter be Used for Flat Towing & Bike Rack
    Yes, you can use a dual hitch adapter for flat towing and carrying a bike rack at the same time. You just need the one with the correct rise or drop, and you can choose from the following: - 2" or 4" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-4 - 2" or 6" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-6 - 2" or 8" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-8 - 2" or 10" Drop/Rise: Roadmaster Dual Hitch Receiver Adapter # RM-077-10 Then to...

  • Dual Hitch Ball Mount For Towing a Small Boat Trailer And Carrying a Cargo Carrier
    I have a recommendation for you as the Roadmaster Dual Hitch Receiver Adapter # RM-077-6 cannot be used with trailer towing. Instead you can use the Gen-Y Phantom X Hitch Ball Mount # GY39VR. This has a similar design with multiple receivers. The Gen-Y is rated for up to 700lbs of tongue weight and 7,000lbs of trailer weight.

  • Is There a Dual Mount Receiver Which Allows For a Cargo Carrier While Towing a Car Using a Dolly?
    The Roadmaster Dual Hitch Receiver Adapter is available in different drop/rise sizes. 4" # RM-077-4 6" # RM-077-6 8" # RM-077-8 10" # RM-077-10 These would allow you to flat or dolly tow a car with a Cargo Carrier # e98874 being used to carry additional gear.

  • Will The RV Rider Bike Rack Work With Dual Hitch Adapter While Flat Towing?
    Yes, the Hollywood Racks RV Rider Bike Rack # HLY64FR will work with the Roadmaster Dual Hitch Receiver Adapter # RM-077-6. This will allow you to still be able to flat tow your Chevrolet Spark as well.

  • Can the Roadmaster Dual Hitch Receiver Adapter be Used w/ a Winch?
    No, it definitely can not handle a winch! We have encountered this question before and Roadmaster has repeatedly shot it down. The Roadmaster Dual Hitch Receiver Adapter item # RM-077-6 can only be used while flat towing and using an accessory like a cargo carrier or bike rack. Gen-Y on the other hand has a ball mount that will work great for exactly what you're wanting to do. It is the Gen-Y Adjustable 2-Ball Mount w/ Stacked Receivers item # 325-GH-314. This is built for a more heavy-duty...

  • Recommended E-Bike Rack for a 2020 Fleetwood Discovery Flat Towing a Chevy Colorado
    For your 2020 Fleetwood Discovery 38K I recommend going with the Hollywood Racks RV Rider Bike Rack for 2 Electric Bikes # HLY64FR. This rack can be used at the rear of your Fleetwood Discovery while you flat tow, has a max capacity of 80 lbs per bike - for a total of 160 lbs, and since the # RM-077-6 you have has a tongue weight of 400 lbs you'll have plenty of capacity for everything. As far as stowing the tow bars when not in use, you're going to run into a space issue unfortunately,...

  • Swagman Bike Rack for Use on Towed Vehicle
    I do have a great option for you, however the Swagman Chinook 2 Bike Platform Rack # S64683 referenced in your question is not rated for use at the rear of a towed vehicle. The ride at the back of your towed Jeep Grand Cherokee is going to be quite a bit different than at the rear of the RV or a standard passenger vehicle and this can put more stress on the rack during travel. Because of this only certain carriers are tested and approved for this application. If you want to use the Swagman...

  • Will Roadmaster Dual Hitch Receiver Work For Flat Towing & Carrying Scooter
    Hey Brian; the answer is likely no, but it depends on the weight of the Vespa. The Roadmaster Dual Hitch Receiver Adapter with 2" or 6" Drop/Rise # RM-077-6 has a 400 lb tongue weight capacity, so the weight of the Vespa and carrier, along with the tongue weight of your flat towed vehicle can only be 400 lbs. I assume the weight of those is going to be more than 400 lbs, but if it's not then you can use it; otherwise it would be too much weight.

  • Availability of Dual Hitch Receiver Adapter for 2-1/2" Trailer Hitch Receiver
    I believe you are looking for a dual hitch receiver adapter like the Roadmaster # RM-077-6 that's directly compatible with the 2-1/2" receiver on your Ford F-250. While there isn't an adapter like this available that's designed for 2-1/2" receivers, you can still use a 2" model like this one by simply adding a reducer sleeve like # C45405 to your truck's receiver. This will reduce the 2-1/2" receiver to a 2" opening so that this and other 2" accessories can be used. I have attached a...

  • Vehicle Protector Compatible With Dual Hitch Adapter & Blue Ox Tow Bar
    We have an option for you, though the way the Roadmaster Tow Defender Protective Screening # RM-4750 installs onto the receiver means it isn't going to be compatible with a dual-hitch adapter. Instead, what you can use that will work with a dual-hitch adapter and your Blue Ox tow bar is a Blue Ox protective guard: - Blue Ox KarGard Towed Vehicle Protector # BX8870 This will do a superb job of keeping your towed vehicle safe, and because it mounts on your Blue Ox tow bar (on all tow bars...

  • Dual Adapter For Flat Towing & Carrying Bike Rack
    While there isn't an adjustable option, there are dual hitch adapters for flat towing that allow you to tow your vehicle and carry a bike rack at the same time. The right one just depends on the amount of rise or drop you need. Also keep in mind the use of an adapter will reduce the tongue weight capacity of your hitch by 50 percent, and that the rise or drop will depend on the way the adapter is turned. - 2" or 4" of Rise/Drop: Roadmaster Dual Hitch Receiver Adapter # RM-077-4 - 2" or...

  • Flat Tow Vehicle While Also Using Bike Carrier
    Yes, this is exactly what the MaxxTow Dual Hitch Extender for 2" Trailer Hitches, # MT70070 is intended for. However, keep in mind that per manufacturer this reduces your hitch rating by 50%. The extender has a weight rating of 400 lbs. tongue weight and gross trailer weight rating of 4,000 lbs. so please compare this to the vehicle you are flat towing. While the # MT70070 is designed to allow you to add an accessory such as a bike rack and use the tow bar, you cannot use an additional...

  • Hitch Adapter to Allowing Towing and Cargo Carrier Installation
    You can use Curt Multipurpose Ball Mount part # D210 to both tow your boat trailer AND use your hitch cargo carrier. Please refer to the linked photo. This item has 500-lbs tongue weight capacity for the receiver and 750-lbs for the ball mount part you'll use to tow. Please note that when mounting an accessory in this receiver, your hitch's tongue weight capacity will be reduced by 50 percent.

  • Recommended Dual Hitch Adapter for Newmar Baystar Towing 2013 Jeep Wrangler Unlimited
    Thank you for providing those helpful measurements. With the 8" difference I would go ahead and choose the Roadmaster Dual Hitch Receiver Adapter, 2 " or 8" Drop/Rise # RM-077-8 over the # RM-077-6. Loading it won't make much of a difference on the height. Also, the flat towed vehicle adds no tongue weight so really there should be no sag at all. Even if you did somehow drop 2" after loading your motorhome you would still be in the safe zone, which is +/- 3" from level. If you want to...

  • Best Way To Lower Your 2 Inch Hitch Tow Angle
    I have the perfect thing! The Roadmaster Dual Hitch # RM-077-6 is unnecessary for your application. Grab the Patriot Hitches Adjustable Drop Hitch Receiver Adapter # PH67SR. This has a 700lb tongue weight capacity and a 7,000lb gross trailer weight capacity. I know you don't need the whole 11 inches of drop but it's adjustable so you can find the perfect height you need. This also can be used with many different attachments so it's very versatile and that is always a plus in my books! Check...

  • Roadmaster Hitch Adapter for Flat towing a 2018 Jeep Rubicon and Two E-Bikes
    I recommend the Roadmaster Dual Hitch Receiver Adapter, 10" Drop/Rise item # RM-077-10. This adapter was designed for this type of set up. Your Jeep Rubicon and Swagman E bike rack weigh well below the 10,000 lbs maximum capacity of this hitch. I have attached a review video as well as a picture that show this rack being utilized in the same way.

    The dual hitch adapter we carry with the highest tongue weight capacity is the Roadmaster Dual Hitch Receiver Adapter part # RM-077-6 for 6" rise or part # RM-077-8 for 8" rise. They both have a 400 lb tongue weight capacity. Please note that this adapter is designed for flat towing only. If you can give me a better idea of what you are using the adapter for we may have alternative options if the above will not work.

    I recommend using the Roadmaster Dual Hitch Receiver Adapter # RM-077-6 for your bike rack. This adapter will lower your tow bars by 2" which you will want to ensure still give you the +/- 3" height needed for the tow bars to safely operate. The other 2" receiver is raised 6" for the bike carrier. This lift will ensure that your tow bars have clearance from the bike rack or bikes depending on your carrier.

  • Can Roadmaster Dual Hitch Receiver Adapter Be Used for Cargo Carrier While Flat Towing
    Yes, the Roadmaster Dual Hitch Receiver Adapter # RM-077-6 is designed with this exact type of situation in mind! If you don't already have a cargo carrier I recommend using the Flint Hill Goods # FHG27ZR as it has an aluminum construction which means it does a great job at resisting rust and corrosion plus it's also very lightweight (it only weighs in at 29 lbs). You won't want to add an extension to this adapter or the tow bar as that would then add too many moving parts and make the...

  • Which Roadmaster Dual Hitch Adapter For Carrying Bike Rack While Flat Towing
    Since the receiver height and the base plate height of the vehicle is the same, you won't need to worry about keeping the tow bar level. If your bike rack has an angled shank with a couple inches of rise to it, you could use the # RM-077-6. If the bike rack has a straight shank, you'll want a dual-hitch adapter with a larger rise such as # RM-077-8 for an 8-inch or # RM-077-10 for a 10-inch rise to move the bike rack up and out of the way. The adapters have a tongue weight capacity...
