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

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:

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:

I have never had an issue with anything from etrailer



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:

Reliable product



by:

It was just what we needed. E-trailer had them in stock. They shipped the next day, and we received them as promised. Thanks, e-tailer.



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:

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:

Received earlier than expected and the quality is excellent



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:

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:

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:

I received the hitch quickly and it was exactly as show and described on the website.



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:

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:

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:

E-Trailer always delivers.



by:

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



by:

Shipping was super easy and fast



by:

The hitch adapter is well constructed... and we're testing it out this weekend. I may want to change to an adapter with a 4" drop... The 2" drop lets the bicycle carrier interfere with the Blue Ox tow bar... I'm thinking that using the 4" drop, and turning it upside down so that the bike carrier rides higher would give more space for the Blue Ox tow bar... Not your fault, will I be able to exchange the 2" drop adapter for a 4" drop adapter?



by:

Perfect for adding bike rack on top of Nighthawk tow hitch



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:

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:

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



by:

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

  • Can You Use Bike Rack on Back of Motorhome with Blue Ox Tow Bar and KarGard
    In order to flat-tow a vehicle and carry bikes at the same you'll need a dual hitch adapter like the Roadmaster Dual Hitch Receiver Adapter for Tow Bars part # RM-077-2 or part # RM-077-4. In most cases, your bikes won't come into contact with the vehicle during turns but we can't say definitively that's that case for every vehicle as there are simply way to many factors. That said, the arms on Blue Ox tow bars are pretty long so this will increase your clearance. I'd also recommend a hanging...

  • 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.

  • 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...

  • Can Either Receiver be Used for 10K Towing Capacity of Roadmaster Dual Hitch Receiver Adapter
    If you're wanting to use the Roadmaster Dual Hitch Receiver Adapter # RM-077-2 for towing a tow dolly then yes, either receiver can be used. If you're talking about towing a trailer then we need to find you a different adapter because these are only designed for flat tow situations. An alternative solution is to use the Replacement Shank for Gen-Y Adjustable Ball Mount # 325-GH-404 instead. This is a much more rugged option designed for towing as it has a tow weight rating of 10,000 lbs...

  • Which Hollywood Bike Rack For Carrying 2 e-Bikes on Motorhome and Flat Towed Jeep
    From what I read online, it appears that the Rad step thru e-bikes weigh around 65 lbs. The weight of your bikes alone would rule out the Hollywood Racks # HR1450Z you'd mentioned, as its capacity is 50 lbs per bike so we'll move on. The # HLY84FR Sport Rider SE has plenty of capacity at 80 lbs per bike, and could be used on your Jeep as well as on your motorhome without issue, but Hollywood Racks hasn't approved it for use on a flat towed vehicle, because the rack hasn't been tested...

  • Can Roadmaster Dual Hitch # RM-077-2 be Used When Flat Towing Grand Cherokee
    The Roadmaster dual hitch adapter part # RM-077-2 would work well for flat towing your Grand Cherokee with an Avail tow bar. It was designed for flat towing and has a 10k weight capacity so it would easily handle the weight of your vehicle. It would add 9-1/8 inches to the distance between your RV hitch and the tow bar.

I believe from everything you are saying that you are trying to use the Roadmaster Falcon All Terrain Tow Bar # RM-522 and the Swagman G10 S64682 with your Roadmaster Dual Hitch Receiver Adapter # RM-077-2.

    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...

  • Bike Rack Recommendation for Carrying Two E-Bikes and Flat Towing Honda CR-V
    Not all bike racks are rated for the rougher ride quality at the rear of a motorhome but the Hollywood Racks Sport Rider SE Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # HLY84FR is and has a capacity of 80 lbs per bike so it would be perfect for your application. You are most likely going to need a dual hitch adapter like the part # RM-077-2. This allows you to carry a bike rack in the top hitch opening and tow your vehicle in the bottom hitch opening.

  • Carrying Bikes While Towing a Pop Up Camper with a 2003 Dodge Ram
    We do have a few different items that you could use to tow the pop up and carry bikes at the same time but the Roadmaster dual receiver # RM-077-2 is only for flat towing (towing a vehicle behind a motor home). The first option you have is to use a towing bike rack. We have several different options for towing bike racks and I have included a link to them for you. The towing racks we carry handle from 2 to 4 bikes depending on the model. Some require an extra long ball mount and will say...

  • Availability of Dual Hitch Adapter With No Drop
    Having your towbar within 3 inches high or low of level is perfectly acceptable, according to Blue Ox and Roadmaster. If the # RM-077-4 would allow the towbar to be within that amount plus or minus of level, the dual hitch adapter would work just fine. We don't have any dual hitch adapters that have a receiver that would be inline with that of the coach.

  • Towing a Pop-Up Camper and Carrying Bikes at the Same Time on a 2015 Dodge Grand Caravan
    First, you would be limited to the 345 pounds tongue weight as specified in the manual for your 2015 Dodge Grand Caravan. Also, the use of a dual receiver will reduce the tongue weight capacity of the hitch by 50 percent from 345 pounds to 172.5 pounds. The combined tongue weight of the trailer and loaded bike rack could then not exceed 172.5 pounds. Since the dry tongue weight of the trailer is 245 pounds you would be over capacity. But what will work is a multipurpose ball mount # D210....

    The Roadmaster Dual Hitch Receiver Adapter, Part # RM-077-2, has a rated tongue weight capacity of 400 pounds. Its intended purpose is to allow use of an accessory such as a bike carrier or cargo carrier at the same time that a tow bar is being used, however, it can be used while towing a dolly as well. Just not a trailer. Please keep in mind that any type of hitch extender or hitch adapter will reduce the tongue weight capacity of the hitch on which it is installed by 50%.

    Actually, I'd recommend the Roadmaster # RM-077-2 Dual Hitch Receiver you'd already looked at.

If the 2-1/4 inch drop will place your tow bar more than 3 inches plus or minus out of level, you can use the # MPG544 but it will lower the tongue weight capacity of your hitch by 50% because it extends out further than the # RM-077-2.
