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

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:

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:

Fits very well on the RV. Sturdy and should tow the truck very well, while holding the bike rack above.



by:

Works great for being able to put our bikes between the RV and the truck we tow.

Still works great and Roadmaster stood behind the product when we had an issue with it. Very pleased!

@Martha We're happy to hear that Roadmaster took good care of you!


by:

Excellent service, good prices and super fast shipping. 2 different orders arrived in 2 days! Thanks for everything eTrailer and William!



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:

Hitch fits to loose inside the receiver. Anything I can get to remedy this issue? Thank you.



by:

This dual hitch receiver was extremely well made and was exactly what i was looking for. It allowed me to use my tray style bike carrier and my storage platform on my RV. The final result is a compact solution that seems worry free for my RV needs.



by:

very well made..works great



by:

Excellent service ‘ fast delivery and good price



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.)

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:

Super heavy duty. This thing looks and feels really well built.



by:

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



by: 07/31/2023

Life saver! Does the work as expected



by:

Good guilty, timely delivery, & reasonable price. E trailer is the best



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!

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.



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.

Year 2 update: Still excellent, hitch will outlive me. The double receiver works well as a bike rack mount above the towbar.



by:

Works perfect to tow a trailer and also carry a bike rack.



by:

Perfect fit exactly size very quick shipping as described



by:

Very nice delivery greatly appreciated



by:

Professional and prompt response to my unique ordering situation. Thanks!



by:

Great product



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:

Very strong hitch. ETrailer.com does a great job providing help when needed and the best reviews.



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.

  • Dual Hitch Receiver Adapter For Flat Towing That Offers 10" Of Rise/Drop
    I went ahead and took a look, and it appears the closest I was able to find is the: -Roadmaster Dual Hitch Receiver Adapter, 2" or 10" Drop/Rise # RM-077-10. This dual hitch receiver adapter can give either 2"-10" of rise or drop depending on the application, has a gross towing weight capacity of 10,000-lbs, and has a maximum tongue weight capacity of 400-lbs. Unfortunately, there is not a dual hitch adapter that has both a 6" rise/drop and a 10" rise/drop. I have also attached a diagram...

  • 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.

  • 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.

  • 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...

  • Is Roadmaster Dual Hitch Adapter Class 3 Rated
    The Roadmaster Dual Hitch Receiver Adapter, 2" or 10" Drop/Rise # RM-077-10 is not Class 3 rated because only hitches are rated by class as opposed to any adapter. And for question two, actual weight is pretty irrelevant in all honesty; Roadmaster's engineers have determined the # RM-077-10 is able to withstand the very fluid ride of a flat towed vehicle and its smooth suspension but not the extremely rough, bouncing, constant motion of a trailer and its very basic suspension.

  • Dual Hitch Adapter With 10 Inch Drop For Flat Towing & Carrying Bike Rack

If you want to flat tow your vehicle and carry your bike rack and need a 10" drop you would be able to use just the # RM-077-10.

  • 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...

  • Recommended Dual Hitch Adapter and Cargo Carrier for Flat Towing/Carrying Bike Rack and Cargo Carrie
    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...

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.

    There is not a maximum length ball mount or hitch extension that can be used in a flat-towing setup.

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.

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...

  • Dual Hitch Adapter that Can be Used When Towing or with Tow Dolly
    The company that designed the # RM-077-10 (Roadmaster) primarily works with vehicle flat towing which is what they intended this adapter for. 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.

  • 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 # C45405 for your 2-1/2 inch hitch so that it would work.
