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? 200668

Ask the Experts about this Roadmaster Accessories and Parts

  • How To Carry Bikes While Flat-Towing a Chevy Sonic Sedan
    Yes, I do have an option for you to carry bikes with your flat-tow setup. However, since there is not a trailer hitch for your vehicle yet and you don't want to use a trunk mount or roof rack bike rack then you will have no other option but to use a dual hitch adapter and place the bikes on a hitch mounted back rack between the tow vehicle and toad. For this, we have a few options for you depending on your rise/drop needs. In order to determine what your rise/drop needs are we will...

  • Which Dual Hitch Receiver For Flat Towing Vehicle and Carrying Bike Rack
    Actually, I'd recommend the Roadmaster # RM-077-2 Dual Hitch Receiver you'd already looked at. This adapter is specifically designed for flat towing a vehicle, so it won't lower the capacity of your hitch. 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 # MT70070 but it will lower the tongue weight capacity of your hitch by 50% because it extends out further than the # RM-077-2. I've linked to product description videos for...

  • Can I Use # RM-077-2 to Tow Trailer and Carry Bike Rack
    Flat towing is when you use a tow bar like # RM-501 and base plates like # BX2258 to tow another vehicle. Often our customers will tow their car behind their motorhome. I have included a FAQ article which explains flat towing for you to check out. We have several adapters that offer 2 receivers like the Roadmaster Dual Hitch Receiver Adapter, # RM-077-2, which you reference. You could also use Curt Multipurpose Ball Mount, # D210, which has a receiver on top and ball mount on the bottom. When...

  • How to Carry Bikes While Flat Towing a 2018 Toyota Corolla iM
    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...

  • Bike Rack for Use with a Roadmaster Dual Hitch Receiver Adapter and ReadyBrake Elite Tow Bar
    Any bike rack that you could use, see link, would most likely have to come off first before being able to easily fold and stow the tow bar. Out of the available bike racks I recommend the Swagman Dispatch # S64684 because it will be a great fit in the 2 inch receiver in # RM-077-2. I have linked a video and instructions for the bike rack for you.

  • Where is Rise and Drop Measured From on Roadmaster Dual Hitch Adapter
    The Roadmaster Dual Hitch Receiver Adapter for Tow Bars - 2" Hitches - 2-1/4" Rise/Drop # RM-077-2 does measure 2-1/4 inches from the center of the hitch pin hole on the shank to the center of the hitch pin hole on the receiver. You definitely will want to move your Thule EasyFold XT # TH903202 bike rack off of your flat towed Buick because this rack is not approved for use on the rear of a flat towed vehicle (it is approved for use on a motorhome). That means if something were to happen...

  • How To Carry Bikes On Back of Motorhome While Towing a Car
    In order to carry a bike rack while also flat-towing a vehicle you'll need a dual hitch adapter, the Roadmaster Dual Hitch Receiver Adapter part # RM-077-2, part # RM-077-4, or part # RM-077-6. Then for a bike rack, you'd just need to make sure it is rated for use on a motorhome for which we have several options, the Hollywood Racks RV Rider 2 Bike Platform Rack part # HR1600 is what I recommend. I have attached a full list of options below.

  • Will Swagman E-Spec Bike Rack Have Clearance to be Used When Flat Towing
    I think you'll be just fine using the Roadmaster Dual Hitch Receiver # RM-077-2 with the Swagman E-Spec Electric Bike Rack # S94FR although you will only be able to find out for sure after taking a measurement with your Wrangler connected to your motorhome. The E-Spec rack will extend a total of about 29 inches from the face of the Roadmaster adapter, and if your tow bar has telescoping arms, the distance between the bike rack and Jeep should still be far enough to avoid any damage....

  • Can Roadmaster Dual Hitch Receiver Adapter # RM-077-2 Be Used with Bike Rack and Towbar
    Yes, the Roadmaster Dual Hitch Receiver Adapter # RM-077-2 can be used simultaneously with both a hitch-mount bike rack in the upper receiver and a tow bar in the lower receiver to flat tow your dinghy. However, the Swagman XC 2-Bike Platform Style Rack # S64650 cannot be used on the rear of your RV. Bike racks that are to be used on motorhomes and RVs must be built specially to withstand the vertical and lateral forces found at the rear of such vehicles. In the same way that a seat...

  • Choosing Bike Rack to be Used While Towing a Camper
    The Dual Hitch Receivers such as part # RM-077-2 cannot be used for towing a trailer. These receivers are meant for use with a towbar carrying a rolling load and an accessory such as a bike rack or cargo carrier. We offer a Curt Ball Mount with 2 inch Receiver, part # D210, which should work for your needs. This ball mount has a tongue weight capacity of 750 lbs, so the trailers tongue weight and the weight of the bike carrier plus the weight of the bikes cannot exceed that figure. Another...

  • Dual Hitch Adapter for Towing PWC Trailer and Carrying Bike Rack
    The Curt Ball Mount part # D210 would work well for you. It is a ball mount that has a hitch opening above it that you could use for a bike rack. I attached a review video for you to check out for more info as well. The # RM-077-2 that you referenced should only be used for flat towing a vehicle and is not rated for trailering use.

  • Adapter Needed for Carrying Bikes on RV While Flat Towing
    We do have some options available for you. The Roadmaster dual hitch receivers, part # RM-077-2 for a 21/4" Rise/Drop and part # RM-077-4 for a 4" Rise/Drop, were created just for this purpose. You can flat tow your vehicle with the bottom receiver and then use the top receiver for a bike rack. The top receiver for each product is rated at 400 lbs Tongue Weight (TW) so you need to be under that capacity for your bikes. Be sure to stay within the 3" safe zone (see attached picture)...

  • Dual Hitch Adapter Recommendation for Carrying Scooter Carrier and Flat Towing Vehicle
    For flat towing setups like yours we have dual hitch adapters like part # RM-077-2 which will allow you to flat tow with the bottom hitch opening and then carry a hitch accessory like your scooter carrier with the top one. This has a tongue weight capacity of 400 lbs too. This would be the best option we 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...

  • Towing a Dual PWC Trailer and Using Cargo Carrier at the Same Time
    For your cargo carrier, a better option would be the Curt Trailer Hitch Ball mount with 2 Inch Receiver, part # D210. Keep in mind that this ball mount has a tongue weight capacity of 750 lbs. This means that the tongue weight of your PWC trailer, the cargo carrier and anything placed on it can weigh no more than 750 lbs. The Roadmaster Dual Receiver Adapter, part # RM-077-2 is not designed for towing a trailer, it is meant for rolling loads like a vehicle being towed using a tow bar.

  • 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...

  • Towing a Boler Travel Trailer and Carrying Bikes at the Same Time
    To be able to tow your Boler travel trailer and carry bikes at the same time I recommend the Curt multipurpose ball mount # D210. I have linked a video review for you. The top receiver portion accepts a 2 inch accessory and has a 350 pound tongue weight capacity. The whole ball mount is rated for 7,500 pounds gross trailer weight and 750 pounds tongue weight. So the combined weight of the loaded bike rack and the trailer's tongue weight cannot exceed 750 pounds. The Roadmaster high/low...

  • Recommendation for Carrying Bikes While Towing a Trailer at the Same Time
    The Roadmaster Dual Hitch Receiver Adapter, # RM-077-2, is for tow bar use only and cannot be used with any type of trailer. But there may be another option. You may be able to use a towing bike rack, like # C18013, depending on how many bikes you wish to carry. I have included a link to our towing bike tracks for you to view. Please note that the weight of the rack plus the weight of the bikes will count against the tongue weight capacity of the trailer hitch. Another option is to...

  • Can a Dual Hitch Receiver Be Used to Carry a Bike Rack and a Cargo Carrier
    Dual hitch receivers, like the Roadmaster Dual Hitch Receiver Adapter, # RM-077-2, are designed for flat towing a vehicle behind an RV and having the ability to carry a bike rack or cargo carrier in the top receiver. A cargo carrier and bike rack cannot be used together. For your situation I recommend using a roof mounted bike rack like the Swagman Rooftop Bike Rack, # S64720, which is one of our most popular roof mounted bike racks. If you do not have a roof rack on your 2010 Ford Escape,...

  • How to Fully Open Tailgate on Truck and Not Hit the Trailer Tongue Jack
    The Roadmaster Dual Hitch Receiver, # RM-077-2, is designed to be used only when flat towing a vehicle. This product cannot be used when towing a trailer. Also, using any other hitch extension will cause you to loose 50 percent of your tongue weight capacity. If your truck hitch has a 300 lbs tongue weight rating, then using an extension will lower that rating to 150 lbs. The best option would be to go with a side mounted trailer jack, like the Pro Series Round Bolt-On Jack # PS1400300303....

  • Dual Hitch Adapter for Towing a 2005 Jeep Wrangler and Carrying 2 Bikes on a Hitch
    A dual hitch adapter, or almost any adapter for that matter, will reduce your tongue weight capacity, but not your towing weight. The Jeep is supporting its own weight, and not pushing down on the hitch, so it doesn't contribute anything to the tongue weight in this setup. You can use the Roadmaster Dual Hitch Receiver, part # RM-077-2 in this situation because there is no tongue weight to worry about, and this part's weight capacity is 4000 pounds, enough to pull your 2005 Jeep Wrangler....

  • Dual Hitch Adapter for Bike Rack While Dinghy Towing Cadillac SRX
    There is such a product, the Roadmaster Dual Hitch Receiver Adapter for Tow Bars # RM-077-2, which is designed to do precisely what you are wanting to do. You will also need a hitch lock such as # e98880 to secure this adapter. Additionally, please keep in mind you will need to use a bike rack that is rated for use behind an RV due to the excessive bounce that occurs at the back of a long vehicle. I highly recommend checking out the Thule Doubletrack # TH990XT for this as it has reinforced...

To do this you will need to use an adapter that is specifically designed for this purpose like the Roadmaster Dual Hitch Receiver Adapter for Tow Bars part # RM-077-2 which has a 2-1/4" rise/drop. This adapter will not decrease the hitches capacity like most others would. Please keep in mind that because the bike rack is being used on the back of the RV you will...

  • Can Roadmaster Dual Hitch Receiver Adapter, Part # RM-077-2, be Used with a Towing Dolly
    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%.

  • 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...

  • Curt Multi-Purpose Ball Mount Recommendation
    I think the closest thing to the Roadmaster Dual Hitch part # RM-077-2 that you referenced that would let you tow a trailer and have a hitch opening above it for an accessory like a bike rack would be the Curt Ball Mount and Hitch Receiver part # D210. I attached a review video for this product for you to check out also.

    The Roadmaster # RM-077-2 Dual Hitch Adapter isn't meant for towing a trailer, only for a rolling load like a vehicle being flat towed. We do have other dual-hitch adapters, but using them will lower the tongue weight capacity of your hitch by 50 percent. If your existing hitch has a 600 lb tongue weight capacity, using an adapter of any kind would lower that to 300 lbs, which wouldn't be enough for your travel trailer. There are some possible solutions, however. Curt makes a Multipurpose...
