• High Capacity Dual Hitch Receiver With Capacity Greater Than 5,000lbs
  Roadmaster offers a Dual Hitch Receiver, part # RM-077-4 that has a 10,000 lb towing capacity. 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. If you're wanting to tow a trailer and carry a hitch mounted accessory at the same time, I'd recommend using the # D210...

• Recommendation for Transporting Bikes While Flat Towing Vehicle
  The Roadmaster Dual Hitch Receiver Adapter # RM-077-4 referenced in your question is designed specifically to allow you to use a bike rack while towing your vehicle behind an RV. The center of the hitch pin hole on the adapter that will be used for the bike rack extends 9-1/2 inches from the center of the hitch pin hole on your hitch receiver. I have attached an image to clarify this dimension. The issue though with using your Thule Doubletrack Bike Rack # TH990XT is that it is not actually...

• Using Dual Receiver Adapter # RM-077-4 For a Winch Mount and Towing a Car Hauler
  Per its manufacturer, Roadmaster, the Dual Hitch Adapter you referenced, part # RM-077-4 cannot be used for towing a trailer. It is designed for a rolling load only. 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. Also, a trailer hitch is designed to withstand horizontal pulling forces or tongue weight suspended from it, but a pulling force coming from an upward...

• Recommended Bike Rack to Use on a Class A Motorhome and Toyota Corolla With a Class I Hitch Receiver
  Since you are wanting to use a bike rack on a Class A RV you will want to go with one that has been tested and approved for use on an RV. The Swagman Chinook 2 Bike Platform Rack # S64683 that you referenced has not been approved for use on an RV. A similar bike rack that is made by Swagman and is rated for use on an RV is the Dispatch 2 Bike Platform Rack # S44FR. This has pretty much all of the same features as the Chinook minus the tilting feature. The reason why there are certain...

• Dual Hitch Adapter And Bike Rack For Behind a RV Motorhome When Flat Towing
  You are going to want to use the Roadmaster Dual Hitch Adapter # RM-077-4. Since the bike rack is going behind your motorhome and carrying E-Bikes I recommend the Hollywood Racks RV Rider Bike Rack # HLY64FR as it is rated for use behind motorhomes and the frame mounted connection will allow you to attach to the seat post since most E-Bikes have an alternative style frame for the battery.

• Parts Needed to Flat Tow a 2018 Ford Fiesta SE Hatchback
  I would love to help you get absolutely everything that you need to flat tow your 2018 Ford Fiesta SE Hatchback.

• RV Bike Rack Recommendation for Use When Flat Towing Vehicle
  At the rear of a trailer or RV the ride quality is very rough when compared to the ride quality at the rear of a passenger vehicle. Reason being the suspension isn't as sophisticated and there is a longer distance between the rear axle and the rear of the trailer which exaggerates the movement of the trailer when hitting bumps. Because of that only a few bike racks were designed to be reinforced enough for that type of use. The Swagman Dispatch part # S44FR is a great RV approved bike...

  I do have another option for you, but you are correct that the Roadmaster Dual Hitch Receiver Adapter # RM-077-4 would not work with your Jeep sitting +2" already because you would be sitting with the Jeep at +4" with the # RM-077-4 adapter. We do have the Curt Dual Hitch Extender # D-192 which will maintain your current height for your flat tow set up and provide a second hitch receiver with a 5-3/4" rise for you bike rack.

• Can Thule OutPace 2 Bike Carrier Be Used On Motorhome Or On Flat Towed Vehicle?
  Thanks for checking, Angie. While the Thule Outpace 2 Bike Rack # TH39SA is rated for passenger vehicles and motorhomes, it’s not currently approved for use on flat-towed vehicles like your CR-V in tow. The added torque from towing can stress the rack, so we’d recommend going with an RV-rated model like the Hollywood Racks RV Rider Bike Rack # HLY64FR if you need it to ride while towed. You can absolutely use the Outpace when driving the CR-V or motorhome on its own, though! If you are...

  Hey Jim, I believe what you are looking for is the Roadmaster Dual Hitch Adapter part # RM-077-4 which has a hitch opening that drops down 2 inches and then a second opening that would be used in the rise position at 4 inches of rise. This has two more inches of rise on the top opening than the part # RM-077-2.

  In order to flat-tow a vehicle and carry bikes at the same you'll need a dual hitch adapter like the Roadmaster Dual Hitch Receiver Adapter for Tow Bars part # RM-077-2 or part # RM-077-4. 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.

  There are no spare tire bike racks rated for an RV or camper spare tire.

• Best Way to Tow a Trailer and Attach a Bike Rack to the Same Hitch

This adjustable ball mount has four 2" receiver openings that will allow you to use both a hitch mounted bike rack and tow your trailer. This ball mount has a 12,000 lbs towing capacity and a 1,500 lbs maximum tongue weight. This will not reduce your motorhome's...

• Solution to Use Thule Bike Rack While Flat Towing Jeep Wrangler
  It is true that you should not use your Thule T2 Pro XTR 2 Bike Platform Rack # TH83JV on your Jeep Wrangler when it is being flat towed. The reason is the amount of movement that far behind your motorhome results in the rack not being stable; this is also why this rack should not be used on the back of a trailer. What you can do instead is use a dual hitch receiver adapter which will allow you to both flat tow your Jeep and use your bike rack. The correct one will depend on the rise or...

• Can the Roadmaster Dual Hitch Receiver Be Used For a Bike Rack and Cargo Carrier
  I do have an option for you but I cannot advise you combine two hitch adapters together like the Roadmaster Hitch Extender part # RM-071 and the Roadmaster Dual Hitch Receiver Adapter part # RM-077-4 as this would be very unsafe. However, if you need to carry both bikes and extra cargo I do still have an option for you. I recommend the Hollywood Racks Sport Rider SE2 Platform Bike Rack w/ Cargo Carrier part # HR1450Z-85.
