Perfect fit, Correct item, and all four 4 locks were keys alike perfect ,
Great job!! E-Trailer and fast arrival. Your on the A- 1 list, Thank You,



by:

As always, I can count on etrailer's exceptional customer service and fast delivery.



by:

WOW, need I say more! I ordered this on a Thursday with no expectation as to when it would get there, thinking sometime the following week. I didn't even bother to see when it would get there yet and to my surprise there it was on Saturday. The icing on the cake, I didn't pay anything for delivery. Thank you etrailer!



by:

Works great tire mount in one side tow bar in the other.



by:

What’s Rocky the product work exactly how I was hoping it would. It held up by and gave me the drop by needed to tow my vehicle behind my RV so I’ve been very happy with it.



by:

Good product, allows bicycles to be carried above hitch that tows our vehicle.



by:

Item promptly shipped and delivered! Still waiting for my new RV to get delivered to try it out.

I have bought many products from eTrailer and have always been happy with their products, prices and service!



by:

Looks to be very strong and well built exept that the holes on the middle tube, which slide into your receiver,are not perfectly lined up. I had to wallow one side out a smidge to get the keeper through.Other than that, no problems.



by:

High quality piece. Welding very good. Quick shipping. I won't worry about equipment failure flat towing our F150 Ford pickup.



by:

Solved my dilemma on how to use my back rack and small trailer at the same time. Sturdy!



by:

This adapter does the job it is supposed to but,,,,,when using this on the motorhome, it would be better if it was a couple inches longer to get the attachment a little farther from the coach. Perhaps offering it in various lengths might be an idea. The fit is also a little bit sloppy and as a result the rack that goes into it bounces a bit and we therefore tie the bikes to the coach to stop the bounce



by:

Received my RM o772order, did a dry fit with road master dual hitch receiver,every thing look great. .



by:

Ordering was simple ;tracking was right on and hitch was delivered quickly! Excellent and quality made dual 2inch hitch I will definitely recommend this product!



by:

Looks well made and exactly what I need.



by:

My hitch extension bent and I was in desperate need for a replacement. etrailer and Adam made the process a breeze. We found the correct part, it was shipped out that day and arrived right on schedule. The customer Service and follow up have been outstanding!



by:

Doesnt fit correctly with my trailer even though the rep said it would. dont bother trying the return it though, 100% satisfaction guarantee if bull. if you try mounting to your rig, it is no longer new. eTrailer sucks.



by:

Gives enough clearance for attaching the bike rack and working with the Blue Ox. Perfect solution for using more than one receiver at a time.



by:

This is a much higher quality (thick and heavy) than I imagined it would be; I'm pleasantly surprised. I'll be using it to mount a trailer hitch cargo carrier and a dog step at the same time when we go on long vacations.



by:

The product was well built, the receiver end was solid so the Anti-Rattle lock would not have worked as it requires hollow receiver. This is a 10,000 pound rated product. I intended to use to add my existing bike rack and Tow bar together, but the bike rack prevented the Tow bar from being added and so I had to send it back and get a different bike rack that fit on my Tow bar. I did keep one of the locks and added to my Alpha Tow bar for Anti-Rattle and Locking.



by:

The hitch adapter is well built and has worked flawlessly. I actually use it with my Honda Pioneer 1000-5 during duck season and it allows me to use my folding cargo carrier on top and keep a ball receiver on the bottom for pulling trailers.



by:

Perfect for my needs. I use the top hitch for a bike rack and the bottom for pulling my toad. I did need to get longer cables for my particular tow bar. You may not need to with yours. For now, I leave the receiver on the RV with the bike rack attached so I am ready to go should I need to pull my toad. I have so far driven over 3000 miles with out a problem.



by:

exactly as advertised and very heavy du ty



by:

Beefy. I have no doubts of the capacity of either side of this hitch adapter, there's plenty of weld to hold it all together. Very few options will provide minimal drop (for an off-road trailer) and minimal rise on the other side for an additional bike rack or cargo carrier. Jeeps are tough since you need to be able to open the gate. This one clears no problem. My spare is up on a slant back carrier, but I think the stock spare should clear as well. Get you a "Trimax THC200 Universal Anti-Rattle Clamp Fits 2" Hitch" and this thing is solid as stone.



by:

The hitch has held up over Alaskan roads towing a jeep, but it does not sit level in the receiver so the tiny little bit that it sags is exaggerated when the tow bar is connected. Paint starting to peel with wear after a year.



by:

Very good quality! Fits perfectly!

This double hitch has been fantastic. Well made and allows me to mount my bikes on back of the MH and connect a Toad. Great product.

  • How To Carry E-Bikes and Flat-Tow a Vehicle on the Back of an RV
    In order to both carry bikes and flat-tow a vehicle at the same time, you'd need to use an adapter on the motorhomes hitch, I recommend the Roadmaster Dual Hitch Receiver Adapter like part # RM-077-2 as it's designed for this exact purpose. In order to choose the correct one, you'll need to make sure your tow bar is within 3" of level while using the adapter. The above offers a 2-1/4" drop but if you need a different one you can choose from the list below. If you don't know how much drop...

  • What Dual Receive do I Need for Flat Towing My Jeep and a Bike Rack with 2 e-bikes?
    Hello Gary, Great question! For your Jayco Class C, the best dual 2” high-low hitch adapter for your setup is the Roadmaster # RM-077-2. It’s rated for 10,000 lbs towing and 400 lbs tongue weight, which will work well for both your NSA Ready Brute tow bar and your bike rack with two e-bikes (260 lbs total). It also provides the 2” height adjustment needed between your motorhome’s hitch and the Jeep’s base plate. The Let's Go Aero is actually my go to for locking hitch pins, so I would...

  • Can MORryde Hitch Mount Stabilizer be used with Dual Hitch Adapter
    Hey Robert, yes you could use the MORryde Hitch Mounted Stabilizer # MR22AR in a dual hitch setup like the Roadmaster # RM-077-2 and this is a clever solution but you should note that using a hitch extender like this does cut the tongue weight capacity of the hitch it's installed in by 50 percent so hopefully that won't be a problem. What bikes do you have?

  • Can I Use The Roadmaster Dual Hitch Receiver Adapter # RM-077-2 With My Blue Ox Tow Bar
    If your Blue Ox tow bar is an RV mounted tow bar, then part # RM-077-2 will work if your receiver is a 2 inch by 2 inch receiver. An RV mounted tow bar will have the shank to fit into one of the 2 inch by 2 inch openings of part # RM-077-2. If your Blue Ox tow bar is a vehicle mounted tow bar, then part # RM-077-2 will not work, as it will have a ball mount coupler on the end of the tow bar. As long as your Blue Ox tow bar is an RV mounted tow bar, as it would disconnect from the vehicle...

  • Better Clearance to Carry Trailer Hitch Mount Wheelchair Carrier on 2011 Mazda CX-7
    The issue that you are going to run into if you use Roadmaster Dual Hitch Extender # RM-077-2 is the tongue weight capacity will be reduced 50 percent. However, if you use a ball mount like # D210 you will get a 6 inch rise and 7-1/2 inch extension from the hitch pin hole to the center of receiver's hitch pin hole. Best of all with the D210 the capacity is not reduced. I have included a video review of this ball mount for you to check out.

  • Recommended Bike Rack to Use on a Class A Motorhome and Toyota Corolla With a Class I Hitch Receiver
    Since you are wanting to use a bike rack on a Class A RV you will want to go with one that has been tested and approved for use on an RV. The Swagman Chinook 2 Bike Platform Rack # S64683 that you referenced has not been approved for use on an RV. A similar bike rack that is made by Swagman and is rated for use on an RV is the Dispatch 2 Bike Platform Rack # S44FR. This has pretty much all of the same features as the Chinook minus the tilting feature. The reason why there are certain...

  • 2 Bike Rack For Use Between a Class A Motorhome and a Towed Vehicle
    It sounds like you are looking for a Dual Hitch Adapter, see link. I would recommend the Roadmaster Dual Hitch Receiver Adapter, item # RM-077-2, for towing a vehicle and using a bike rack in the top receiver. You could use the Swagman Platform-Style 2 Bike Carrier, item # S64663, which would be a good choice, or any of the bike racks we have rated for use behind a RV that will fit in a 2 inch hitch, see link.

  • Will the Roadmaster Dual Hitch Adapter Work w/ a Bike Rack and Extended Ball Mount?
    Yes, on the bike rack but no on the Hidden Hitch Ball Mount item # 80232. You can't tow a trailer with the Roadmaster Dual Hitch Receiver Adapter item # RM-077-2 anyways. That is only designed to be used for flat-towing plus you will lose half of your hitch's capacity because it's an adapter. Instead, you will want to use the Replacement Shank for Gen-Y Adjustable Ball Mount item # 325-GH-303. This will have no impact on your hitch's capacity, has a 10,000 lbs towing capacity, and a 1,500...

  • Can Roadmaster Dual Hitch Receiver be Used for Dirt Bike Carrier
    So long as your total tongue weight is less than 400 lbs you can use the lower half of the Roadmaster Dual Hitch Receiver Adapter for Tow Bars # RM-077-2 for flat towing and the upper half for a dirt bike or motorcycle carrier. The etrailer Motorcycle Carrier # e98873 you referenced weighs 58 lbs. I have added links to video reviews for you to check out as well of both the Motorcycle Carrier # e98873 and Dual Hitch Receiver Adapter # RM-077-2.

  • How Can I Transport My Bike Rack while Flat Towing My Jeep Behind My 2024 Entegra Aspire?
    Hello Tom, Great question, and you are absolutely right to be concerned. When the bikes are blocking the Jeep’s tail lights, it creates a real safety issue and increases the risk of someone not seeing your brake or turn signals in time. The best solution here is to move the bike rack to the back of the motorhome using a dual receiver setup. I would recommend something like the Gen-Y Adjustable 2-Ball Mount with Stacked Receivers, part # 325-GH-414. This will let you run your Blue Ox tow...

We offer a Curt Ball Mount with 2 inch Receiver, part # D210, which should work for your needs.

    Hey Graham! I have a solution for you but the Roadmaster Dual Hitch item # RM-077-2 won't work for a trailer. It's for flat towing and hauling an accessory.

    Hey Jim, I believe what you are looking for is the Roadmaster Dual Hitch Adapter part # RM-077-4 which has a hitch opening that drops down 2 inches and then a second opening that would be used in the rise position at 4 inches of rise. This has two more inches of rise on the top opening than the part # RM-077-2.

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.

    It is not ideal to use any sort of hitch extension with a bike rack, especially on the back of a motorhome. There is simply too much stress on the bike rack due to the rough ride. That said, if the bike rack makes contact with the road there is really only one option. There are no rules against using a hitch adapter with a bike rack on a motorhome.
