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

by:

Perfect for my application.



by:

Works great! I use it on my motorhome to carry my bikes with a Rocky Mounts Carrier and flat tow my car with my Blue Ox system. It places the bike carrier at an optimal height over the front of the car but my may be different for other bike carriers. Very sturdy and seems to be quality all around.



by:

Everything was delivered fast and in perfect condition.



by:

Excellent workmanship and quality but a little overpriced but not bad definitely will be purchasing more roadmaster accessories



by:

Works great. We're towing a jeep and have a bike rack behind our motor home.

Great. Havent lost the bikes or jeep.

They have not remedied the problem of the rounded receiver. Just bought the 10” rise adapter, absolutely built tough as nails. However, the two have the duel hitch receiver adapter receivers are rolled corner 2” stock. Will not allow 2” square hitch to go inside. Very disappointed as other post stated that problem was resolved.



by:

Great quality. Used for lowering bike carrier that will be used for 2 electric bikes(55lbs each). Reordered same product in 6 inch drop. This should be perfect.



by:

I ordered this to adapt my bike rack to my hitch while I flat towed my car with a Blue Ox Aventa tow bar. I was concerned about turn radius and I stumped the etrailer customer service.
I ended up with about 18” of clearance and 47” from the adapter to car.
I feel it is sufficient.



by:

This specific double hitch is a must when using a Roadmaster 2 tow system and a bike rack. The hitch rases the bike rack up high enough to properly use the tow system.



by:

Wow, excellent customer service. Thank you Jennifer is rare in our world today to say that. Hitch adapter shipped same day on a late afternoon order. No extra effort; just the way this company refreshingly does business. Part arrived promptly and well packaged. No nicks or scratches on the part. Truly was well stored and handled at their warehouse. Following are some pictures of the hitch adapter installed.



by:

I just received hitch today. Pleasantly surprised that it actually arrived earlier than expected. It is every bit as described. Strong and sturdy. Cannot go wrong with Roadmaster. Can’t wait to hit the road. Thank you Natalie with etrailer.com. for your support and quick response.



by:

Shipped alot quicker than anticipated. Great fit for my application. Excellent service. Easy return of previous item. Thank you.



by:

Well made product. Still working great.



by:

I have purchased four front mount hitches from etrailer and quite satisfied with product quality, fit and ease of installation. I purchase the dual receiver adapter to accommodate a winch and be able to use a front tow ball without the extra effort of removing winch to use ball. As usual quality was not an issue with the adapter. The slider on the adapter was solid stock rather than thick wall box tubing lending to superior strength. Welds and engineering are, as always, exceptional. I highly recommend etrailer products.



by:

Very impressed with the quality of the hitch. We purchased a new motor home and needed a different height hitch. Had trouble finding the size we needed until we checked trailer. Thank you for meeting our needs.



by:

Great product! We are able to Mount our bike rack on top and our tow bar in the bottom. Great service from etrailer.com



by:

Appropriately heavy for the job!



by:

I received this product in record time. This is a quality product that solved the problem of using both my bike rack and cargo carrier on the back of my RV. I will definitely be visiting etrailer.com for my future needs.

Glad you like the dual hitch adapter! The adapter has a 400 lb tongue weight capacity, which means that the cargo carrier, whats carried on it, the bike rack and the bikes cannot weigh more than 400 lbs. This figure will be lower if the tongue weight capacity of your RV is less than 400 lbs.



by:

This was the perfect product to get the hitch height of my Class A gasser to the right level to tow a car flat behind it. I just used it this weekend and it has worked flawlessly. I forgot all about it, which i guess it what should happen with this type of equipment. etrailer is extremely helpful on the web page and the phone and I have used them for several purchases since getting my old Class C five years ago.

BTW, this thing is heavy! The receiver tongue is solid steel, not a tube. It has become a permanent fixture in the hitch.



by:

This hitch adapter works great! It allows me to use my bike rack with my cargo rack so we can haul our bikes along with all of our other stuff when we head out on our summer vacation. I also use it regularly as a hitch extender when I need to haul something in my truck with the tailgate down, and we want to take the bike rack. Only, drawback is it is pretty heavy duty (probably more than what I need), but if you are using it with a heavier trailer (e.g., camper or big boat), it probably should be that heavy duty.



by:

Purchased this to use on a 2016 Winnebago Adventurer 37F towing a 2013 Honda CR-V. Attached a Schwegman 2 bike rack on top with a Blue Ox towbar below. Works great, plenty of clearance between the bikes and the car. Only issue is the hole for the pin when attached to the RV could be a little larger. The blue ox locking pins are a tight fit



by:

Great site. Easy to get around.



by:

The hitch is heavy-duty and works as expected. We can mount a bicycle rack or an extra
luggage rack on the back of the RV and still pull our tow vehicle without any problems

The hitch adapter still works great! No problems at all.



by:

This receiver is strong and with the anti-rattle stabilizer has been a great addition to our RV trips to add a bike rack and be able to tow a vehicle.



by:

Great product, I really love this thing! It made it possible to mount a winch to pull cars onto my trailer. Quality is great! Very solid welds.

I have used this hitch adapter for a Winch that I can use to pull cars up onto my trailer. AWSOME PRODUCT! It keeps re-inventing itself every time I use it.



by:

THIS HITCH WAS GREAT IN HELPING LOAD MY TRUCK ONTO TRAILER. THEN WHEN I PULLED MY CAMPER I HAD AN EXTRA PACE TO HOOK MY BIKE RACK IN PLACE SEE MORE FUTURE USE IN COMING TIMES . VERY STURDY AND WELL BUILT.

  • Solution For Carrying 2 Regular Bikes And 1 Electric Bike On 44 Foot Toy Hauler 5th Wheel
    There are only a few bike racks that are built strong enough to be compatible with 5th wheel trailers / toy haulers, so your options are limited. That said, the only 3-bike carrier that will work is the Swagman Original - 3 Bike Rack for 2" Trailer Hitches # S64152-2; this also comes in a 4-bike version # S64400. This bike rack is not suitable for electric bikes as the weight capacity is only 35lbs per bike and your E-bike probably weighs more than that even when the battery pack is removed....

  • Extending Hitch for Bike Rack on 2019 Subaru Outback Wagon
    There are many bike racks compatible with the 4 inch recessed hitch. You will just want to find one with a long shank. Each bike rack we carry will have the measurement from the hitch pin hole to the closest part of the rack so you can confirm fit. For example, the RockyMounts MonoRail 2 Bike Platform Rack - 2" Hitches - Tilting - Wheel Mount # RKY10004 measures 11 inches when carrying and 6-1/4 inches when folded close to the vehicle. Using a hitch extender will reduce the hitch capacity...

  • Can the 8 Drop Dual Hitch Adapter Be Used for Towing
    I do have an option for you but none of the dual hitch adapters that provide adequate drop can be used for towing. Instead, you'd need to go with a standard ball mount with the drop you need like the Curt Ball Mount part # C45090. Then, you can carry the rod rack on the tongue of the trailer (if a-frame) with the Swagman Straddler part # S80503 or on the front of the vehicle with a front mount trailer hitch, the Curt Front Mount Trailer Hitch Receiver part # C31028.

  • What Size Dual Hitch Adapter Is Needed To Carry A Bike Rack Above The Roadmaster Tow Defender?
    I recommend using the Roadmaster Dual Hitch Receiver # RM-077-8 which separates the receivers 8" from bottom edge to top edge of the different receiver. The Roadmaster Tow Defender # RM-4750 sits roughly 4" above the top edge of the receiver and depending on your bike rack this ensures you have enough room to easily move the screen out of the way to disconnect your flat towed vehicle rather than having to unload the bikes over the front of your flat towed vehicle before you can disconnect....

  • Towing Capacity With Dual Hitch Receiver Adapter - Boat And Four Bike Rack
    I understand why someone would want to take their camper, boat, and four bikes RV'ing simultaneously! It sounds like quite the adventure! Let's talk about how it might be possible to make this work. You are correct that if the loaded bike rack is 300 lbs. and your tongue weight capacity is only 500 lbs., you only have another 200 lbs. to play with. It appears that your boat's tongue weight is not known to you. Typically this number is going to be 10-15% of its gross trailer weight, in...

  • Can Roadmaster High Low Adapter be Used with Weight Distribution
    The Roadmaster High Low adapters like the # RM-077-8 that you referenced can not be used with weight distribution as they aren't rated for use when towing trailers. Only when flat towing vehicle which do not have tongue weight. If the goal was to have a second hitch opening to allow for use of a weight distribution system and carry a bike rack we do have the Lippert Jack-It part # LC429756 which attaches to the mounting bracket of the trailer jack and carries a bike rack above the trailer...

  • 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 want...

  • Using Dual Hitch Adapter For Bike Rack and Small Travel Trailer
    You could use a dual hitch adapter like the MaxxTow # MT70070, however doing so will reduce the tongue weight capacity of your hitch by half. You'll want to take a look at the ID sticker on your hitch, and find the tongue weight rating printed there. If the tongue weight of the fully loaded travel trailer plus the weight of the bikes and the rack they're carried on does not exceed half the listed hitch tongue weight, then you'd be safe to use an adapter like the # MT70070. If it does exceed...

  • Hitch Bike Rack and Cargo Carrier on a 2016 Ford Transit Connect Wagon
    I have a possible solution for you, but I don't recommend carrying your Thule bike rack with an aluminum carrier, even though its technically possible. You could use a part like the Roadmaster Dual Hitch Receiver, part # RM-077-8, which offers an 8 inch rise and would give you two 2 inch receiver hitches to work with. The top one would absolutely have to be the bike rack, while the bottom would be your cargo carrier's shank. You would then use an extender in the bottom port to clear most...

  • Can a High-Low Adapter and Dual Hitch Receiver Adapter Be Used In Combination
    The Roadmaster Dual Hitch Receiver Adapter, 8" Drop/Rise # RM-077-8 is made to allow you to tow as well as use an accessory. It will allow you to flat tow up to 10,000 lbs and will allow a tongue weight of 400 lbs. The other dual receiver options do not have the capacity to tow a medium sized vehicle as well as a cargo carrier. The issue you will find with needing a 6 inch high-low adapter that using two adapters at the same time will put too much torque on the hitch and will also put...

  • Solution for Towing Pop Up Level and Also Carrying Bike Rack with Yukon
    First we should determine how much drop you'd need to get your trailer level. Basically you need to measure from the top of the hitch opening down to the ground and then measure from the bottom lip of the coupler down to the ground and compare the two measurements. That difference is how much rise/drop you'd need. From there we can go and determine what would be best bike rack solution. For example we have the Curt # D210 has a hitch opening for a bike rack above a ball mount that has...

  • Recommended Dual Hitch Adapter for Newmar Baystar Towing 2013 Jeep Wrangler Unlimited
    Thank you for providing those helpful measurements. With the 8" difference I would go ahead and choose the Roadmaster Dual Hitch Receiver Adapter, 2 " or 8" Drop/Rise # RM-077-8 over the # RM-077-6. Loading it won't make much of a difference on the height. Also, the flat towed vehicle adds no tongue weight so really there should be no sag at all. Even if you did somehow drop 2" after loading your motorhome you would still be in the safe zone, which is +/- 3" from level. If you want to...

  • Dual Hitch Extender with Rise and Drop for 2 Trailer Hitches
    I recommend theRoadmaster Dual Hitch Receiver Adapter, 8" Drop/Rise item # RM-077-8. This will give you a 8" rise and a slightly longer extension than the one you currently have at 10 3/4" long. This hitch extender also has a higher max towing capacity at 10,000 lbs.

  • Trailer Hitch for Towing and Carrying a Bike Rack
    First, in order to choose the correct ball mount, there are a couple measurements you'll need to take. First, make sure both your vehicle and trailer are parked on level ground; you'll then want to measure from the ground to the top of the inside of your hitch receiver. Next, measure from the ground to the bottom of your trailer's coupler and find the difference between the two measurements. If the height of your hitch is greater, you will need a ball mount with that amount of drop. If...

  • Which Roadmaster Dual Hitch Adapter For Carrying Bike Rack While Flat Towing
    Since the receiver height and the base plate height of the vehicle is the same, you won't need to worry about keeping the tow bar level. If your bike rack has an angled shank with a couple inches of rise to it, you could use the # RM-077-6. If the bike rack has a straight shank, you'll want a dual-hitch adapter with a larger rise such as # RM-077-8 for an 8-inch or # RM-077-10 for a 10-inch rise to move the bike rack up and out of the way. The adapters have a tongue weight capacity...

  • 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...

  • Flat Towing Jeep and Carrying 300 Pound Motorcycle Behind RV
    We do have dual hitch receivers available that feature the kind of tongue weight capacity that should support both the weight from your flat towed Jeep and motorcycle, such as with the Roadmaster # RM-077-6 that has a 400 pound tongue weight limit. As long as the combined tongue weight of your Jeep and motorcycle (be sure to include the weight of the carrier itself as well) falls under this limit then the adapter will be up to the task. The Jeep really won't produce much tongue weight...

  • Can I Use Roadmaster Dual HitchReceiver Adapter to Carry Cargo Basket and Bike Rack on Roadtrek RV
    Yes. You can use the Roadmaster # RM-077-8 on your Roadtrek RV's 2" receiver to carry both a cargo carrier like the Curt # C18151 and a bike rack without any issues. It should be mentioned that because of the extra movement that often occurs at the back of an RV you will need to use a bike rack that is rated for use on the back of an RV. Since you need a 4 bike rack rated for use on the back of an RV, you'll want to use something like the Thule Hitching Post Pro # TH934XTR. Since this...
