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

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:

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:

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:

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



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:

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:

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:

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:

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:

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



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:

Always great.



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:

Very fast shipping and great product



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:

Adam was the person that helped with our orders. Definitely top notch service, order arrived as expected, and I will be working with e-trailer again. Good person to deal with.



by:

Needed this to carry our bikes and tow our car on the back of our motor home.



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:

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

  • Is There A Hitch Riser for a Bike Rack on the Back of a Motorhome
    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. It will however reduce the weight capacity of the hitch most likely. The Roadmaster Dual Hitch Receiver Adapter part # RM-077-2 most closely...

  • Carrying Two Bikes on Rear of 2012 Ford F150 While Towing Forest River R Pod 178
    For starters, be aware that the use of any hitch adapter will reduce the tongue weight capacity of your hitch by fifty percent. So, if the tongue weight capacity of your hitch is 600 lbs (consult sticker on hitch for actual tongue weight capacity), using a dual hitch adapter will lower that tongue weight capacity to 300 lbs. If the hitch or tongue weight of the Rpod is 257 lbs, then your bikes plus the rack you use would need to weigh less than 43 lbs to prevent overloading the hitch (which...

    Best option for a dual hitch adapter for carrying a carrier and towing a tow dolly would be with a Roadmaster Dual hitch adapter part # RM-077-2 and then you'd need to use a motorcycle carrier like the # e98873 for an electric scooter carrier.

  • Does Using Roadmaster Dual Receiver Reduce Trailer Hitch Tongue Weight Capacity when Flat Towing
    In a flat towing situation the use of an adapter like # RM-077-2 does NOT reduce the tongue weight capacity of the trailer hitch because there is very little tongue weight on it when flat towing a vehicle. So you can use this adapter to flat tow your Jeep and to carry a bike rack. In a regular towing situation like towing a trailer and not a vehicle, the use of an adapter or extender reduces the tongue weight capacity of the hitch by 50 percent. This is because the additional length of...

    There are dual hitch adapters you can use when flat towing so you can carry your ebikes, but none have an offset.

  • Needing a Bike Rack to Mount Between a Motorhome and a Flat Towed 2008 Toyota Yaris
    I have a solution for you to add a bike rack on the back of your motorhome to mount between your coach and your flat towed 2008 Toyota Yaris. You will need to add a dual hitch adapter like the Roadmaster Dual Hitch Receiver Adapter for Tow Bars, # RM-077-2. The adapter will allow you to connect both your Blue OX tow bar and a bike rack to the rear of your motorhome. As for a bike rack, I recommend the Curt # C18085 bike rack can carry up to 2 bikes with a weigh capacity of 90 lbs. The...

  • 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...

    Thank you for all of the info and the pictures! 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. You may be able to use the Curt Dual 2" Receiver Tube Adapter # D-192 instead but it only has 3-1/4" of clearance between the top of the bottom receiver tube and the bottom of the top receiver tube so I'm not sure if you will have enough...

  • 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.

  • 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...

  • Can Curt Clamp-On Bike Rack be Used on an RV Towing a Vehicle
    Curt Clamp-On 3 Bike Rack # C18013 is not rated for use at the back of an RV so I do not recommend using it. If you have 3 inches or more free space on the shank you can use Swagman bike rack # S64664. I have included a link to a video review of this bike rack for you. The other option is to use a dual receiver such as # RM-077-2 and then use an RV-approved rack, see link.

    There are only certain bike carriers that are rated for use at the back of a motor home. Towing carrier # C18013 is not one of them so I cannot recommend it for you. that is also probably why you do not see any reviews with a similar set up. But not to worry because I do have a solution for you. You can use a dual hitch receiver adapter such as # RM-077-4 with a 4 inch drop or rise or # RM-077-2 with a 2 inch drop or rise. Then in the upper receiver you can use a motor home approved bike...

    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...

  • Trailer Hitch Mount Bike Rack for Use on a 2004 Honda CR-V Being Flat Towed Behind a Motor Home
    The issue is that when a vehicle is connected to an RV it can change the way that vehicle rides which in turn can put additional stress on the bike rack. So to cover their bases Hollywood Racks has indicated that the Sport Rider # HR1000Z should not be used in any time of towing situation. Not to worry though because you and other RV owners with toads still have some options. There are several racks that you can use at the back of an RV or trailer. This means that you can also use them...

    There are no platform bike racks for ebikes that are able to clear a 17 inch spare tire, but what you may be able to do is use a dual hitch adapter while flat towing your Wrangler. This depends on the rise/drop you need but an example is the Roadmaster Dual Hitch Receiver Adapter for Tow Bars - 2" Hitches - 2-1/4" Rise/Drop # RM-077-2. Then you could put the tow bar in the bottom receiver and a bike rack in the top receiver, one that is rated for use behind a motorhome, like the Swagman...

  • High-Low Adapter for Flat Towing a Vehicle and Carrying a Bike Rack at the Same Time
    A lot depends on the tow bar you are using, the hitch height, and the vehicle being flat towed. The 2 inch drop on # RM-077-2 would be fine if you are using a tow bar that has a shank that fits into a receiver rather than the type that has a coupler which would be more likely to interfere. The 4 inch drop, # RM-077-4, does have better clearance but like you said that will change the angle of the tow bar. You will want the tow bar to be as level as possible. Each tow bar has a little bit...

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...

    It sounds like you need an extended ball mount like the Curt Class III item # C45270. This one is 13" long has a 2" rise and 4" drop. It has a 7,500 lbs weight capacity. I don't know how long your current ball mount is or if it has any drop but this one will definitely be longer than any standard ball mount and give you enough clearance to clear your propane tanks. For a 2" hitch ball I recommend the Curt item # A-90.

  • Roadmaster Dual Hitch Receiver Adapter Recommendation for Flat Towing a 2009 Saturn Vue

This product has a towing capacity of 10,000 lbs and should have no problem flat-towing your 2009 Saturn VUE that weights approximately 5,000 lbs. When in use you will want the tow bar to be sitting as level as possible. If the tow bar is not level you may experience handling problems and tire wear issues on the front tires of the towed vehicle. I attached an FAQ on flat towing vehicle for you to check out also.
