Roadmaster Dual Hitch Receiver Adapter, 2" or 10" Drop/Rise - RM-077-10

Average Customer Rating:  4.8 out of 5 stars   (50 Customer Reviews)

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

by:

I’ve been using this product every day for over a year at this point. On the back of our Class C RV it supports a bike rack carrying 3 bikes (one is a heavy eBike) and a Roadmaster tow bar, which connects to a Jeep Wrangler when we travel. It provides the need height for the bike rack and the drop needed for the tow bar to be level with front of the Jeep. We are full time RVers, so it gets a lot of use. It has worked perfectly and remains in new condition.




by:

One of the two receiver tubes (the 10" drop/rise receiver tube) was too small to accept all three of my 2" hitch accessories (Kuat Bicycle carrier, an aluminum cargo carrier, and tow hitch ). I had to use four(4) 3/8" grinding wheels on my rotary tool and approximately 1.5 hrs of my time to grind the inside four corners to enlarge the receiver tube to get them to fit. (note: the 2" drop/rise tube was the correct size, so it appears to be a production quality issue with just the the one tube.)


Comments
Roadmaster products have a brand specific shape. They have a rounded shape meant to be used with other Roadmaster items. I reached out to the manufacturer and they said the integrity of the adapter is not compromised by having to grind the inside away a little to allow for use with other non Roadmaster products.

by:

I love the product not just for the obvious reasons such as it’s extremely durable and well made for safety but specifically for length of the arm. The arm length is just long enough to clear my hitch rack walls, which allowed me to plug in my bike rack. I would certainly recommend this product to others. I haven’t seen any marketing for this specific use case so have at it.




by:

Perfect fit exactly size very quick shipping as described




by:

This dual hitch receiver adapter is a vital part of my RVing equipment. It allows me to have my toad pulled by my motor home using the lower part of the receiver and also to mount my bikes or fishing cart on the upper part of the receiver. This arrangement gives adequate space vertically and I have no trouble maneuvering around turns. I highly recommend the helpful personnel at etrailer who helped answer my questions about which receiver adapter was best for my application.




by:

This hitch adapter is exactly what I needed and am thankful to have found it. I pull a Mini behind a motor home and like to carry a couple bikes on a bike rack. That left me with a need for two hitch adapters and a drop hitch to match the low height of the Mini with the high hitch on the RV. This adapter provides the perfect solution and provides plenty of room for both applications. Anyone with similar needs, this is your solution!


Comments
After a year, I continue to use this hitch adapter and continue to find it very useful. It still looks great and does everything I had hoped it would.
John S - 10/31/2020


by:

This offers a great solution to my flat towing and bike hauling problem. Thanks to Tammie at eTrailer for offering this suggestion!




by:

Been using it for over a year. Have a bike rack on top and used a winch setup for my trailer to haul trucks up on it. Works great. Built a hitch on my friends rv and he wanted the same setup for his bike rack and towing a trailer behind his rv.




by:

Excellent hitch adapter. Amazingly strong and well built. We've towed our car around 10,000 miles with it so far and zero issues. We ordered the 10" drop hitch and should have gotten the 6" drop hitch, but that's on me. Maybe go a couple of inches less than you think to avoid scraping on inclines. Would buy again, no problem.


Comments
Year 2 update: Still excellent, hitch will outlive me. The double receiver works well as a bike rack mount above the towbar.
Dave B - 05/31/2021


by:

Excellent service as always!


Comments
My Roadmaster Dual Hitch has done everything I expected. I required a 10 for my tow car on my Allegro Bus motorhome just the perfect . And, the upper receiver I use for my E-bike. Now a year later, the quality of craftsmanship and finish still shows.
Hugh - 06/09/2022


by:

Well built product and did what I needed it to do. The rise part of the receiver to install a bicycle rack to keep it above my tow vehicle a lifted Jeep Wrangler. The only negative is the receiver tube on the bottom now drops the hitch basically 2 1/2 inches lower and I now drag the receiver on the ground on driveway / street dips. Would have been better if none rise came straight out. I don’t think I would drag then I should have done more measurements




by:

Great product




by:

Great product. I was able reposition our bikes in conjunction with our tow bar easily.




by:

Well made and just as described.




by:

Great product. Solidly built. I use it to raise a cargo carrier to clear my dingy while towing behind my motor home. Thank you again




by:

I bought this so I could put a bike rack on the back of my motor home while flat towing my car. It worked great had no problems. The bicycles sat up high enough that they did not make contact with the car while turning. Sorry but I don’t have photos at this time.




by:

Received item yesterday. Thank you, your service and delivery was excellent.




by:

This drop receiver allows us to carry bikes or scooter carrier when our "towd" is hooked up with our tow bar.




by:

Works great, 2 day shipping and it got here in 2 days.
Yolanda give me excellent service, need to give her a raise.




by:

The product and purchasing experience was top notch in every aspect, from ordering the product, shipping the product, and follow up after the product was delivered. eTrailer communicated with me every step of the way providing status, expected arrival, and delivery. Thanks for a great experience.




by:

Very heavy duty hitch. Works great. Fast shipping.




by:

This is what I needed




by:

We ordered several products from etrailer. Service excellent and products arrived when they said. Good products! Definitely order from them again.




by:

product was received in excellent condition. Well packed with no scratches. Delivered very promptly. Great service. Will consider etrailer for any future needs.




by:

Perfect fit and incredibly strong. Like the top receiver for bike rack, etc.

  • Can the Roadmaster Dual Hitch Receiver Adapters Be Flipped When Using a Bike Rack
    The Roadmaster Dual Hitch Receiver Adapters like part # RM-077-10 or any of the other adapters I have attached for you in the link below can be flipped so that raised receiver tube is on the bottom with the tow bar or so that the raised receiver tube is on the top for the bike rack. It does not matter which so long as you have the tow bar on the lowermost receiver tube and the bike rack on the uppermost receiver tube. Please note, you will want the connection point for the tow bar (center...

  • Distance Between Hitch Openings of Roadmaster Dual Hitch Receiver Adapter # RM-077-10
    The rise/drop of the Roadmaster Dual Hitch Receiver Adapter # RM-077-10 is the distance from the top of the shank that slides into the vehicle hitch to the top of the receiver openings. So when the adapter is in the drop position and the lower opening is the longer one the distance is 10 inches from the top of the shank to the top of the lower opening and then 2 inches to the upper opening. If you flip the adapter the distance is then also 10 inches of rise and 2 inches of drop. Since...

  • How To Carry Bike Rack and Cargo Carrier Together On Back of Motorhome
    The best option we have to carry both a bike rack and cargo carrier together at the same time on the back of a motorhome would be with a Roadmaster Dual Hitch Receiver Adapter. These adapters are offered in a few different sizes, part # RM-077-10 for example would give you the most amount of space between the two connection points but you also need to have enough ground clearance for this. I have attached the list of options below.

Your Jeep Rubicon and Swagman E bike rack weigh well below the 10,000 lbs maximum capacity of this hitch.

    The best way to flat tow your Fiat 500 or Mini Cooper and also transport your two e-bikes is with a Roadmaster Dual Hitch Receiver Adapter like # RM-077-6. This adapter is specifically designed for this application, providing you with a 2 inch receiver on the bottom for attaching a tow bar and an additional 2 inch receiver on top to attach a hitch-mounted accessory like a bike rack.

  • 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...

  • 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...

    There is not a maximum length ball mount or hitch extension that can be used in a flat-towing setup. However, the further out you go, the less tongue weight the ball mount or extension will be able to carry which is not really an issue for a flat-towing setup but is something you need to keep in mind.

    You can use a Dual Hitch Adapter like # RM-077-2 so you can simultaneously carry a cargo carrier/bike rack and flat tow. There are a couple things to keep in mind, though... Using an adapter will reduce the tongue weight capacity of the hitch by half. Therefore, if the hitch has a tongue weight capacity of 350 lbs, using the adapter will reduce that capacity to 175 lbs. That's not a big deal for the flat towed vehicle, because flat towed vehicles are a rolling load that don't exert any...

  • Could Roadmaster High Low Adapter be Used in 2-1/2 inch Hitch
    Since we don't have a version of the # RM-077-10 that fits a 2-1/2 inch hitch directly your best option would be the adapter with a hitch reducer part # 58102 for your 2-1/2 inch hitch so that it would work.

  • Dual Hitch Receiver Adapter For Tow Dolly And Bike Rack
    We do have a dual hitch receiver adapter that will allow you to use your tow dolly while also carrying your bike rack. The only thing you need to know is the amount of rise or drop you'll need, which will allow you to choose the right one. To determine this, just measure from the ground to the top of your motorhome's receiver, and then measure from the ground to the bottom of your dolly's coupler, and the difference you get is the rise or drop you'll require.

  • Solution to Use Thule Bike Rack While Flat Towing Jeep Wrangler
    It is true that you should not use your Thule T2 Pro XTR 2 Bike Platform Rack # TH83JV on your Jeep Wrangler when it is being flat towed. The reason is the amount of movement that far behind your motorhome results in the rack not being stable; this is also why this rack should not be used on the back of a trailer. What you can do instead is use a dual hitch receiver adapter which will allow you to both flat tow your Jeep and use your bike rack. The correct one will depend on the rise or...

The towing capacity of this is 10,000 lbs which refers to the weight of the vehicle being flat towed and the tongue weight capacity of 400 lbs refers to the weight it can carry with a hitch accessory in the upper hitch opening. The most similar adapter we have would be the # MPG544 that can be used when towing or with a tow dolly.
