Wanted to be able to combine tow hitch and bike hitch. This required a 2" drop and a 4" rise with a 10K lb capability. came thru with product, price, special free shipping, and great customer service. Ordered on Sun and received on Wed and installed on Thur and ready to go! 123010


After 1 year this product is still working as day 1.

Looked for a hitch receiver adapter that supplied two 2" receivers but it both had to be capable of towing the full 5,000 lbs rated tow of our RV. In that way we could rotate the adapter to choose whether we wanted a 4" drop for towing the toad, plus mounting the bike rack, or just a 2" drop for trailer towing. eTrailer had the largest selection, a competitive price, and free shipping of the 24 lbs adapter. The only "fly in the ointment" was UPS turned the upgraded 2 day delivery I purchased when I ordered the adapter on Sunday, into a 6 p.m. Thursday night four day delivery. Not eTrailer's fault. But I expected Murphy's Law to prevail and that's why I ordered the part a week ahead of my need, and paid the extra for 2 day shipping. 330881

I bought 4"/2" drop/rise receiver adapter( RM-077-4) and 2 stainless steel locking hitch pins. I needed the 4" drop to line up our "toad" behind our motor home. This device with the 2" rise solved the problem of, "Where do I hang the bike rack?" and saved me from having to install a hitch on the towed vehicle for that purpose. The adapter and pins were shipped for free and we saved considerably over what we would pay at a nearby major RV retail store. The quality of the locking pins speak for themselves in one word "STAINLESS". I wish they offered a similar quality pin in a side locking model instead of the end locking style. I would definitely replace the so called chrome one I have for the receiver on the coach. 148667

Excellent service from ! I just recieved the Roadmaster drop/rise bar & Roadmaster Quiet Hitch items. Very well packaged, and delivered in a timely fashion. I'll be installing the items on the motorcoach this week. Top quality items at great prices, and excellent service. I'll try to post a pic of everything that I purchased, in use, in the near future. The videos are very helpful, as well as the answers to their FAQs. Tom from Bossier City, La. 101315

I was looking for a way to easily carry and store my bikes while on the road. The Roadmaster Dual Hitch Receiver was the perfect answer. It is well built and, unlike other dual hitch receivers on the market, it did not reduce my towing capacity. And, as with all my purchases from, their website was easy to use and the shipment was accurate and quick. 316454

This is the only dual hitch that I could find that maintained the weight ratings that we needed even when flipped. Most reduced the allowable weight by 50% and could not be flipped. I would be cautious when looking at similar lower priced options when comparing. This receiver is one heavy duty chunk of metal by a recognized manufacture in the industry.. 168340

I had hoped to use the top to carry bicycles, but the carrier we have interferes with getting the Blue Ox tow bar out of its resting cradle. This means that every time you want to unhook, you will have to take the bikes off the carrier and remove the bike carrier to be able to stow the tow bar. The drop down does a good job of making our towing level. 183078

Delivery was expediant as promised and packaging was great with all products arriving without a scratch. This adapter is built like a battleship and more than up to doing the job. The 3 locks, all keyed alike, are all stainless steel, fitting both the adapter and all my hitches perfectly. As always, doing business with e-trailer is again a pleasure. 75691

I purchased this product to add a platform above my tow bar. I flat tow a Jeep Wrangler unlimited behind a Monaco Windsor Motorhome and have no place to carry a spare tire. I will build a tire rack to fit the top receiver. I trust Roadmaster Products. and's price and service is outstanding. Great job 180959

Arrived via external package damage and internally, the paint is intact/fresh looking. It would be difficult to damage this item beyond any paint or label damage as it's made of steel. Item is as expected, nicely executed welds, no burrs or weld splatter and the paint is good. Will fit my intended purpose. 362554

Received this product from etrailer in a very timely fashion. I'm anxious to try it out on our Jayco Seneca RV as we travel to Arizona right after Christmas.

The right fix at the right price. I'm mounting a spare tire carrier up top and a bike rack underneath.The alternative, all-in-one product is probably well-made and does the job but costs about $600. This solved my problem and saved me a bundle. As always, the customer service is icing on the cake. 338126

This dual hitch receiver was exactly what we needed as it allows us to pull our tow vehicle behind our RV and also carry our bike rack between the RV and the tow vehicle. The dual hitch receiver is very heavy-duty and very well constructed. 336040

Do you have a question about this Accessories and Part?

  • Cargo Carrier/Bike Rack Combo Recommendation
  • I have a solution for you, but the # RM-077-4 that you referenced is not designed for what you are trying to do so I cannot recommend it for you. Also, there wouldn't be enough clearance to have both a bike rack and a cargo carrier on this product. The bikes would hang too low and would prevent cargo from being able to be carried with the carrier. Instead I would recommend the Hollywood Racks Sport Rider SE Platform Bike Rack w/ Cargo Carrier # HR1400-85. This is a bike rack/cargo carrier...

  • Thanks for all of the information and research on parts for flat towing your 2005 Mini Cooper behind your Siesta Sprinter diesel Class C motor home. You have most of the parts correct, but there are some specific items you will need for your Mini. First, you need to wire the dinghy so that the combined brake and turn signals on the motor home will activate both the brake and turn signals on your Mini. The brake pedal would activate the brake lights with the key in the position you describe,...

  • RV Rated Spare Tire Bike Rack Recommendation for an Aliner Camper Trailer
  • There are no spare tire bike racks rated for an RV or camper spare tire. However, if your Aliner's bumper is rated for towing and/or carrying weight, we offer several bike rack options that are rated for use behind a camper. Take a look at the Swagman Around the Spare Mighty Rack, # S80500. This rack is designed to fit a 4 to 4-1/2 inch continuous welded square bumper and fit around the spare tire. I have included a link to the installation details and a video review for reference. Another...

  • Availability of Dual Hitch Adapter To Use a Tow Dolly and a Bike Rack on the Back of a Motor Home
  • The Roadmaster Dual Hitch Receiver Adapter, part # RM-077-4, can only be used with a tow bar and bike racks. It is not designed to support the tongue weight of a trailer (or tow dolly). This adapter can be only be used with a rolling load, like when flat towing a vehicle, because there is hardly any tongue weight that is put on the adapter when towing a vehicle with 4 wheels on the ground. A tow dolly will normally have a coupler on the trailer tongue that will attach to a hitch ball...

Check out the picture I attached that shows a tow bar and a bike rack being used with a # RM-077-4 on the back of an RV. You should not have a problem unhooking the tow vehicle if there was a carrier above it either. I attached an FAQ article on flat towing for you...

  • Carrying Bikes at the Back of an RV While Towing a Car on a Tow Dolly at the Same Time
  • There are a couple of hurdles to overcome in order to be able to carry bikes while using a tow dolly at the same time. First there is the drop issue. The most amount of drop from an adapter that we have is 10-1/4 inches, # RM-048-10, which will still work even if it doesn't quite get down to 12 inches. There aren't any dual receivers that you can use that will also have enough drop and work with a tow dolly. So what I propose is to use the above 10-1/4 drop adapter with a different kind...

You can use the dual purpose ball mount # D210. This ball mount has a 2 inch receiver on top for a bike rack or cargo carrier.

I would recommend installing a hitch on the back of your RV.

The D210 can handle a total of 750 lbs tongue weight/7500 lbs towing and the receiver opening can handle up to 350 lbs of tongue weight.

  • Bike Rack Recommendation for an RV Flat Towing a Honda Fit
  • The best option I could recommend for you would be to get a shank mounted bike rack that you could attach to the 6 inch drop adapter you currently have. This would not require the use of an additional adapter that would reduce capacity and would also allow you to tow your setup at it's current height. For a bike rack you would want the Swagman Traveler XCS Bike Rack part # S64664. Check out the review video I attached.

  • Dual Reciever Extensions for Flat Towing a Car and Using a Cargo Carrier
  • Yes we do have an adapter available that should work for you. You could use the Curt Dual 2 Inch Receiver and Extension, part # D-192. You could also use one of the Roadmaster versions, part # RM-077-4 or RM-077-2. These parts are only to be used with a rolling load such as a vehicle being towed with a tow bar and should never be used to tow a trailer.

  • Drop Ball Mount Recommendation for Towing Tow Dolly and Bike Rack that Will attach to It
  • The best solution I can provide for you will be to go with a ball mount that has the amount of drop you need (7 inches), for your tow dolly to attach to and then a bike rack that can attach to the ball mount. For a ball mount you would want the part # C45100 that has a 7 inch drop, and then for a bike rack the Swagman XCS Traveler # S64664 that will attach to the ball mount. The High Low adapters cannot be used with tow dollies.

This ballmount was designed for the application you are describing. It has a tongue weight capacity of 750 pounds.

However, the Receiver is meant for flat towing a vehicle and carrying a hitch mounted accessory, not for towing a trailer. The top receiver has a 400 lb tongue weight capacity, which means that only 400 lbs of downward force can safely be applied to the Dual Hitch Receiver.

  • Options for Mounting Winch to Trailer for Pulling Vehicle on to Trailer
  • The Roadmaster Dual Hitch Adapter part # RM-077-4 just wasn't designed for towing a trailer so it's ratings aren't relevant to trailer towing. Although it has what looks like standard trailer capacities since they weren't rated with a trailer I can't recommend you use it for that purpose. The Curt Dual Hitch Adapter part # D-192 was designed for trailer use, which is probably why it has lower capacities since trailers put more strain on a ball mount than flat towing.

See the link I attached to see them all. It sounds like you are planning on use a dual hitch adapter like the part # RM-077-4 so that you can flat tow your vehicle and carry a bike.

  • Using Roadmaster # RM-077-4 Dual Hitch Adapter for Towing a Tow Dolly
  • Roadmaster doesn't recommend the # RM-077-4 be used for a car dolly because the tongues of car dollies are known to bounce around quite a bit. This bouncing force can multiply the tongue weight exerted on the receiver adapter to well over its capacity, which can damage the dual hitch adapter. The Curt Multipurpose Ball Mount, part # D210 would be a much better choice, as this part is specifically designed to be used for towing. The entire unit has a 750 lb tongue weight capacity, and...

  • The RM-077-4 is not for use with any type of trailer - tow bars only. You could use this to carry a bike rack and tow a vehicle behind a motorhome. We do have a receiver mounted Trailer Hitch Ball mount with 2" Receiver for Bike Racks or Cargo Carriers, part number D210. Using this ball mount with adapter you can tow a trailer and carry a bike rack as long as you stay within the tongue weight capacity and gross weight capacity of the ball mount, ball, hitch and vehicle.

Curt makes a dual receiver adapter, part # D-192 that might work for you, but using any adapter or extender will lower the tongue weight capacity of your hitch by 50 percent.

I will cover each of these for your 2005 Honda Pilot. 1) Tow Bar - You already mention that you plan to use the RoadMaster Falcon 2 Tow Bar, # RM-520. This tow bar has a 6,000 lb capacity and works with all Roadmaster vehicle-specific base plates, EZ, MS, MX, XL and standard. 2) Base Plate Kit - Roadmaster XL Custom Base Plate Kit for 2005 Honda Pilot, # 1544-1. 3) Safety Cables -...

  • Hitch Adapter to Raise Cargo Carrier by 3-4 Inches
  • What you're describing is called a high-low adapter. They work very well keeping the tow bar level when you're flat towing a vehicle, but they can also be used for elevating a hitch mounted accessory. Another option would be the Roadmaster # RM-077-4 dual hitch receiver offers the rise you're looking for. The pin hole to pin hole dimension is 10-1/4 inches which is slightly longer that you wanted, but it should work just fine for you. A third alternative, the Curt # D-192 offers...

  • Availability of Dual-Purpose 2-Inch Hitch Adapter to Allow Towing and Use of Bike Rack
  • The Curt # D210 Multipurpose Ball Mount with 2-Inch Receiver is the item nearest to your requirements. This provides a 2-inch receiver on top, for use with a bike rack, and a ball mount at the bottom that will accept a ball with a 1-inch shank diameter, such as 1-7/8-inch # 19260 or 2-inch # 63845. The other adapters you referenced, Roadmaster # RM-077-4 and Curt # D-192, will not work for you since the Roadmaster cannot be used to tow a trailer and the Curt has the side-effect of cutting...

  • Carrying 200 lb Scooter and Towing a Boat Trailer Simultaneously
  • The only possible way I can think to do what you're asking about would be to use a multi-purpose ballmount like part # D210. However, the receiver portion of the ball mount has a maximum capacity of 350 lbs. This means that the weight of the scooter, plus its carrier couldn't weigh more than 350 lbs. The entire ballmount/receiver unit has a tongue weight capacity of 750 lbs, which means that the tongue weight exerted on the receiver plus the tongue weight applied to the trailer ball couldn't...

  • A Dual Hitch Receiver for Tow Bars and Flat Towing a Vehicle Can Not be Used to Tow a Trailer
  • First, the dual receivers like # RM-077-4, cannot be used for towing like you have said. One issue is that you would have to add a ball mount to the end of the receiver and that extra link in the chain can create too much stress for anything other than flat towing. Though this item is rated for 400 pounds tongue weight, the tongue weight of a trailer can fluctuate as you travel whereas a vehicle is being towed with 4 wheels on the ground and has virtually no tongue weight. These receivers...

  • Platform-Style Bike Rack Recommendation for a Motorhome Towing a Chevrolet Malibu
  • The Hollywood Racks Sport Rider 2 Bike Rack, # HR1000, that you referenced would be an excellent choice for your Malibu or Grand Cherokee, however, this rack is not rated for use behind a motor home. The back end of a motor home subjects hitch mounted accessories to more jarring and bounce than a passenger vehicle, truck or SUV because the rear end is further away from the rear axle. Because of this, there are only a few bike racks that are compatible with motor homes. We do offer one...

  • Length of Shank on the Roadmaster Dual Hitch Receiver Adapter #RM-077-4
  • I went out to the warehouse and measured from the center of the hitchpin hole to the back of the 4 inch rise on the Roadmaster Dual Hitch Receiver Adapter, part #RM-077-4. That measurement is 6-3/4 inches so it will be close, you will need to measure from the center of your hitch pin hole to the farthest out part of the bumper to determine if dual receiver will work for your towing setup. The measurement is the same to the back of the 2 inch rise opening. The overall length of this item...

  • High/Low Adapter with an 8 Inch Drop to Flat Tow a 2012 Chevy Equinox and Bike Rack Recommendation
  • The dual receiver we have with the most rise or drop is # RM-077-4 that you have referenced. One of the receivers has a 4 inch drop. That is not quite enough if you need 8 inches. But there are other options. First, you do need an 8 inch drop so that is a given, use # RM-048-8. This adapter has a 10,000 pound gross towing weight capacity and 400 pound tongue weight capacity. What you can do is add a trunk mount bike rack to the 2012 Chevy Equinox. There are 2 and 3 bike carriers...

  • Can I Use a Roadmaster Dual Hitch Receiver Adapter with a Bike Rack and a Tow Bar with a Cover
  • Yes, the Roadmaster dual hitch receiver adapter # RM-077-4 can be used with a tow bar like the Roadmaster Falcon 2 # RM-520 you referenced, and a bike rack at the same time. You can have the cover on your tow bar while a bike rack is in place because the cover is specific to the Falcon 2 tow bar # RM-520. This receiver adapter has a 10,000 pound towing and 400 pound tongue weight capacity. I added a photo of a similar setup. If your bike rack isn't RV and motorhome certified, view the...
