Add a bike carrier or cargo carrier with the dual hitch receiver.by: David08/14/2022
Exactly what I needed. Now able to add storage box and still pull tow Dolly.
by: Kenneth03/10/2023
I contacted etrailer and spoke with Terri N. I had previously purchased on 3 separate occasions another brand of dual hitch (none from etrailer) which all bent when pulling my 2018 Jeep Wrangler behind our 2014 Fleetwood Bounder 35K Motorhome with a Hollywood bike frame carrying 2 Rad Power e-bikes. Apparently, we were using the wrong adaptor. She was VERY helpful with information, discouraging more than 1 hitch adaptor and recommended the 10,000 pound dual hitch receiver with a 2-4 in drop/rise. So far, it seems to be working fine. My only concern is that there is not enough clearance to fold up my Blue Ox tow bar while connected to the hitch. Also, the front of the Jeep bumper is VERY close to the bike rack upon turning the Motorhome.
by: Randy01/25/2024
I first went with a ridged brand that had a recall the sent me a replacement (I used the original for approximately one year with no problems)the replacement hitch bent immediately and when I contacted ridged they blamed my driving habits since receiving the roadmaster I’ve added a heavier vehicle and a very heavy spare tire rack and no problems
by: Teampez03/16/2024
Very impressed with the quality of this hitch adaptor! I have purchased many items from etrailer and never disappointed!!!
by: John O.03/31/2014
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. Etrailer.com 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!

Excellent option to add a bicycle rack when towing. Easy to use. Well made. I highly recommend.
by: Gary 10/05/2023
Item is well made and will provide more flexibility with having a bike rack hitch and towing hitch at the same time.
by: Daniel Cowell04/07/2024
Its great, showed a lot of people. Every one i showed said they want one.
by: George05/08/2023
This was a change to ensure it met the 10K tow capacity of the Roadmaster system. The bike rack and the tow system are a little close so considering another extension for the Roadmaster system to allow a little more clearance when turning.
by: John 01/17/2024
Great product, works as expected.
by: Maurice B06/27/2016
Love it !
Only one I`ve found that fits my need with both upper & lower receivers having a strong tow rating.
by: John 06/03/2023
Good quality and heavy duty. Will work great being able to tow my jeep with the bike rack on top.
by: Darryl 08/24/2023
Thank you . Easy order. Shipped fast. Product is strong. I always get a good experience with E-Trailer.
by: Richard 04/29/2023
Etrailer’s customer is actually customer service. There’s real people who are there to help. Kate helped me get my order the next day after I realized I accidentally switched the billing and shipping addresses on the order form.

Great product and well built. Easy access on their website with fast shipment.
by: Jim M.08/23/2017
Needed a drop hitch for the Falcon 2 tow bar to get within the specified 3" variance off level as specified by Roadmaster. Also, we wanted to have the second receiver for a hitch mounted bike carrier. Problems solved! Thanks etrailer!

Still performing and doing the job of bicycle hitch and hitch for the Falcon II tow bar.
by: Mark 06/02/2023
Exactly what I needed. Our A class motorhome sits higher than our ex-C class did and angles the toad pull line too much, thus the 4" drop. When pulling our little fishing boat we had no where for our e-bikes, thus the 2" rise. All should be perfect now. Next problem is June and first of July is completely booked with family stuff. Can't test anything until July 12th, 2023. Going fishing. Will update if a problem but I cannot forsee one.
by: Steve P01/27/2017
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.

Still working great one year later!!
by: James02/16/2019
Received my 4 inch hitch adapter almost two weeks ago. Finally had the time to install and test it on my RV. The adapter fits great and the welds look very well done. The 4 inch drop along with my blue ox’s 4 inch drop are the perfect combination for my tow package. I plan to add a new bicycle carrier in the near future and this adapter was chosen with that in mind.

1 year usage and still great purchase for towing my Mini Cooper. I love the versatility of adding my bike carrier in front of the toad vice being on back of towed car.
by: Jeff01/23/2019
Our new double 10000lbs rating receiver is perfect on our class a. Now can 4wheel down tow our Honda crv and put our bike carrier on the same receiver with plenty of clearance for the sharpest of turns. Very well made nice piece of equipment. Great service and with pin purchase and receiver, free shipping.

by: Leo S.03/11/2019
Product has worked great. I use it to tow a vehicle behind my Motorhome on the lower hitch and carry two heavy electric bikes on a bike carrier on the top hitch. I have put more than 15000 miles on it so far without any issues.

by: Mr. Glamping08/23/2019
For my toad needed an extension for a 4" drop and a connection for a bike rack. No one locally had what needed. etrailer had the exact item I needed to haul my toad and bike rack on motor home for the rated capacity I needed. Quality built product. Delivered product exactly as shown on web site.

I bought this to mount a bike rack over my tow bar behind the motorhome. It has worked great.

See what our Experts say about this Roadmaster Hitch Adapters
- Dual Hitch Adapter Recommendation for Towing More than 5,000 lbsWe have the # RM-077-4 which has a towing capacity of 10,000 lbs and is designed for use in flat towing setups.
view full answer... - Can Roadmaster Dual Hitch Receiver Adapter RM-077-4 Be Used with Tow Bar and Cargo CarrierThe Roadmaster Dual Hitch Receiver Adapter # RM-077-4 does allow flat towing with a tow bar in the lower receiver while a cargo carrying device is used in the top receiver. Usually a flat towed vehicle puts very little tongue weight (TW) on a hitch so this means that almost all of the adapter's capacity will be available for the carrier and scooter. The adapter has a total TW rating of 400-lbs. This means that the combined weight of your scooter AND it's hitch-mount carrier cannot exceed...
view full answer... - What Dual Hitch Adapter Can I Add To My Pace Arrow RV To Tow Vehicle And Haul Cargo Carrier Without knowing what your tongue weight is for your Pace Arrow RV I would not be able to tell you what exactly you can and can't tow. The Roadmaster Dual Hitch Receiver Adapter # RM-077-4 has a tongue weight up to 400 pounds, using this adapter will also reduce your tongue weight capacity by 50%. For example if your tongue weight is 500 pounds it will automatically turn into 250 pounds. If your tongue weight is still high enough after the tongue weight cut you will be able to use the cargo...
view full answer... - Can Roadmaster Dual Hitch Adapter Handle Weight of Tow Dolly, Towed Vehicle and Bike Rack The tongue weight of the Roadmaster Dual Hitch adapter part # RM-077-4 is 400 lbs so it can handle the tongue weight of the tow dolly plus the weight of the Equinox and the bike rack with bikes. Since the front axle of the towed vehicle sits over the axle of the tow dolly, very little weight is transferred to the tongue of the tow dolly. The tow dolly we carry is engineered so the tongue weight is between 80 and 100 lbs with the vehicle loaded.
view full answer... - Dual Hitch Receiver to Flat Tow a Jeep and Use a Cargo Carrier at the Same TimeThere is a dual hitch receiver that will allow you to flat tow and use a cargo carrier but it is a little lower than the 6 inch rise/drop you are looking for. We have # RM-077-4 which has a 4 inch rise/drop. But as long as the tow bar is still in the safe zone as far as being level the 2 inch difference would not be a problem. The pin hole to pin hole distance is 9-1/2 inches on center. I have linked a help article that explains the safe zone.
view full answer... - Solution for Using Tow Dolly and Hitch-Mounted Bike Rack Behind RVWe have actually reached out to Roadmaster and verified that the Dual Hitch Receiver # RM-077-4 can indeed be used with a tow dolly. As long as you stay under it's 400 pound tongue weight capacity this is a perfect solution for you. I have attached a short video review below that you can check out as well.
view full answer... - Can Dual Hitch Adapter be Used with Motorcycle Carrier and Tow Bar without Turning InterferenceIf you used the Roadmaster Dual Hitch Receiver Adapter # RM-077-4 with your tow bar setup and motorcycle carrier it would take a really sharp turn to potentially cause interference since tow bars are pretty long. I don't think you'd have an issue at all but the first few tight turns you make you might have a spotter make sure the clearance is okay.

- Do Both Hitch Openings of Roadmaster Dual Hitch Receiver Adapter # RM-077-4 have Same CapacityEither hitch opening of the Roadmaster Dual Hitch Receiver Adapter # RM-077-4 has a 10,000 lb towing capacity when flat towing a vehicle. This is not designed to be used for towing a trailer.
view full answer... - Adapter to Allow Vehicle to Be Flat Towed and Carry Cargo CarrierDual hitch adapters are designed for exactly what you are looking to do. To allow you to flat tow a vehicle and carry a hitch accessory like a cargo carrier. The part # RM-077-4 would work well for you and would be a great option.
view full answer... - Can Either of the Receiver Openings of the Roadmaster Dual Hitch # RM-077-4 Be Used for Flat TowingYes, either hitch option can be used to tow your vehicle and the other to carry a bike rack. If you wanted to use either of the hitch openings for your bike rack and the other for flat towing it would be fine.
view full answer... - Dimension from Hitch Pin Hole to Back of Receiver for Roadmaster Dual Hitch Receiver AdapterThe correct measurement you mentioned on the Roadmaster Dual Hitch Receiver Adapter, 4" Drop/Rise # RM-077-4 is 6-5/8". I'm not sure if there was an older design that had the 5-1/2" that was referenced, but I confirmed the 6-5/8" with my contact at Roadmaster and will be updating the 5-1/2" answers.

- Recommended Dual Receiver Adapter For Bike Carrier And Flat-Towing The Roadmaster Dual Hitch Receiver Adapter with dual 2 inch receivers, part # RM-077-4 is designed to do exactly as you mentioned you want to use it for. The upper receiver is intender to be used with a hitch mounted accessory like a bike rack and the lower receiver is intended to be used with a tow bar only. The adapter is not to be used with any type of trailer and has a towing weight capacity of 10,000 lbs with a tongue weight capacity of 400 lbs. If you do not have the required...
view full answer... - Can Roadmaster 077-4 Dual Hitch Receiver be Used Upside Down When Flat Towing VehicleYes, either the top or the bottom hitch opening on the Roadmaster adapter part # RM-077-4 can be used when flat towing a vehicle. I attached a picture that shows it used "upside down."

- Adapter Recommendation for 4 inch Drop and Second Hitch Opening for Carrying Bike RackSounds like what you are looking for is the Roadmaster High Low Adapter part # RM-077-4 which will provide you with the 4 inches of drop you need plus an additional hitch opening above for a hitch bike rack to install.
view full answer... - Can Tow Bar Stow Vertically if Used in Dual Hitch AdapterIf you use the Roadmaster Dual Hitch Adapter part # RM-077-4 with a bike rack in the upper hitch opening and a tow bar in the lower opening you would not be able to stow the tow bar in the upright position until you removed the bike rack from the adapter.
view full answer... - Will Using Roadmaster Dual Hitch Receiver RM-077-4 Reduce Tongue Weight Capacity of a Trailer HitchRoadmaster dual hitch receiver # RM-077-4 would not reduce the tongue weight capacity of the hitch when used as intended (flat towing while carrying an accessory). The tongue weight applied by a towed vehicle is minimal anyway so it is unlikely that the hitch tongue weight capacity would be exceeded anyway even if the capacity was reduced.
view full answer... - Potential Interference w/Toad and Cargo Carrier when Turning Using Roadmaster Dual Hitch ReceiverWhether or not there will be interference when using a cargo carrier in the Roadmaster dual receiver # RM-077-4 depends on several factors. The size of the carrier, the length of the tow bar, the height and width of the vehicle all play a role in determining interference. If the cargo carrier has a rise in the shank that could raise it higher than the front end of the vehicle and there would be no interference. The only way to know for sure is to test it. The adapter is going to move...
view full answer... - Recommended Dual Hitch Adapter for Flat Towing and Carrying Bike RackThe closest available solution, and what I recommend is the Roadmaster Dual Hitch Receiver Adapter, 4" Drop/Rise # RM-077-4. The distance between the hitch pin holes on the receivers is 6-1/4" and there are 4" between the top of the lower receiver and bottom of the top receiver. I've also linked photo with some dimensions that will allow you to determine if this will work for you, but it is the tallest dual hitch adapter I've seen that can be used for this purpose.

- Can the Roadmaster Dual Hitch Adapter Be Used to Flat Tow a Vehicle and a Hitch carrierYes, you can use this Roadmaster Dual Hitch Receiver Adapter # RM-077-4 to use a tow bar to flat tow a vehicle and then simultaneously carry a hitch accessory like a bike rack or cargo carrier on the top hitch opening. 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 to check...

- Can Roadmaster Dual Hitch Adapter # RM-077-4 be Used with Tow Dolly and Towing CapacitiesWe have actually reached out to Roadmaster and verified that the Dual Hitch Receiver # RM-077-4 can indeed be used with a tow dolly. This has a total towing capacity of 10,000 ls and has a tongue weight rating of 400 lbs. So if you can verify that the weight of your motorcycle and carrier is less than 400 lbs this would work well for you.
view full answer... - How to Use a Bike Rack While Flat TowingI may have an option for you but the Dual-Hitch Adapter # RM-077-4 is the largest drop we have in a dual. An option is to add a hitch receiver to your toad and carry the bike rack on it if everything is compatible. It all depends on how many bikes you're trying to carry and if you already have a bike rack you're trying to use.
view full answer... - Dual Hitch Adapter with 4 inches of DropSounds like you have a high low adapter currently that has 4 inches so for a similar dual hitch adapter you'd want the part # RM-077-4 which has the same 4 inch drop and a hitch opening above it for your bike rack.
view full answer... - Length of Shank on the Roadmaster Dual Hitch Receiver Adapter #RM-077-4I 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...
view full answer... - Can Roadmaster Dual Hitch Adapter RM-077-4 be Used with Flat Towing SetupYes the Roadmaster Dual Hitch Receiver Adapter # RM-077-4 can be used with a flat towing setup like you have currently to tow your Fiat 500.
