Roadmaster Accessories and Parts - RM-048-6

  • Tow Bar
  • Hitch Adapters
  • High-Low Adapter
  • Roadmaster
  • Fits 2 Inch Hitch
  • 6 Inch Rise/Drop

Make up for the height difference between your RV and towed vehicle with this hitch adapter. Provides either a 6" drop or a 6" rise. Solid shank provides strength and durability.


Features:

  • Allows for proper positioning of tow bar
    • Makes up for height difference between RV's hitch and towed vehicle's base plates
    • Also lets you mount a bike rack, cargo carrier, or other 2" hitch accessory
  • Provides either drop or rise for adequate ground clearance
  • Constructed of sturdy steel
    • Solid shank for suprerior strength and durability
  • Resists rust and corrosion with black powder coat finish
  • Hitch pin and clip or hitch lock sold separately
  • Made in the USA


Specs:

  • Application: 2" x 2" trailer hitch receivers
  • Drop/rise: 6"
  • Receiver: 2" x 2"
  • Tongue weight: 400 lbs
  • Gross towing weight: 10,000 lbs
  • Length: 14" overall
    • 3-7/8" From center of hitch pin hole to angled brace
    • 9-1/2" From center of hitch pin hole to center of pin hole
  • Limited Lifetime Warranty


Note: This adapter is designed to flat tow a vehicle only. Do not use to tow a trailer. When using with a hitch-mounted accessory, such as a bike rack or cargo carrier, the tongue weight of your hitch will be reduced by at least 50 percent.


Most tow systems require some sort of hitch accessory to either raise or lower the tow bar to an appropriate level. The "Safe Zone" for a motor-home-mounted tow bar ranges from 3" above level to 3" below. Car-mounted models must be absolutely level. This high-low adapter can provide you with the necessary drop or desired rise to achieve a level tow bar setup.

  • Does Curt High Low Adapter part # C26FV Have a Tongue Weight Rating
    Hey Eric, since Curt designed the high low adapter part # C26FV for flat towing vehicles only it was never tested for a tongue weight rating and therefore it doesn't actually have one. Instead we have the Roadmaster part # RM-048-6 which also has a 6 inch rise/drop but has a tongue weight rating of 400 lbs. You can't tow a trailer with this but you could use a hitch cargo carrier or a bike rack.

  • How to Raise Hitch Mounted Bike Rack for Additional Ground Clearance
    A hi-low adapter like the part # RM-048-6 you mentioned is designed for a rolling load like a vehicle being flat towed behind a motorhome. Although it hasn't been designed for a hitch mounted accessory like a bike rack, it can be used for that purpose. Do not use to tow a trailer. When using with a hitch-mounted accessory, such as a bike rack or cargo carrier, the tongue weight of your hitch will be reduced by at least 50 percent..

  • Solution for Towing Trailer Level that is 6 Inches Higher Than Tow Vehicle
    I do have a solution for you, however high-low adapters like the Roadmaster # RM-048-6 that you referenced are only designed for flat towing a vehicle. They are not suitable for towing a camper/trailer. To get the rise you need to tow your trailer level, you will instead want to look at a ball mount with around a 6 inch rise. I recommend taking a look at the Draw-Tite Ball Mount # 2793. This ball mount is compatible with 2 inch hitch receivers, features a 6-3/4 inch rise (or an 8 inch...

  • Can an Extender be Used with the Roadmaster High-Low Adapter for Bike Rack Clearance?
    That's definitely not a good situation. If you raise the bike rack up a bit will that give you the clearance you're needing? Adding another extender to your Roadmaster Adapter # RM-048-6 is never a good idea because it adds more potential fail points and pretty much every adapter manufacturer states not to use more than one adapter either. What I like to recommend to people is the Replacement Shank for Gen-Y Adjustable Ball Mount # 325-GH-304. If you flip it upside down you can use the...

  • Scooter Carrier for Rear of Motorhome
    We do offer a motorcycle/scooter carrier that's rated for use on a motorhome, part # UF48-979033 from Ultra-Fab. As long as the scooter's tires aren't wider than 5 inches, the carrier should be compatible with your scooter. In order to use a motorcycle/scooter carrier, the hitch on the motorhome would need to have sufficient capacity to handle the 300 lb weight of the scooter and the 45 lb weight of the # UF48-979033 carrier. There is no way to add a bike rack and bikes to the Ultra-Fab...

  • Parts Needed To Flat Tow a 2024 Ford Escape
    Since the 2024 Ford Escape is unchanged from the 2023 I see no reason you would not be able to use the Roadmaster Base Plate # RM77GR on the Hybrid trims. I recommend using the Roadmaster Nighthawk Tow Bar # RM-676 and the Accessory Kit # RM-9284-2 to connect your Escape. You will also need a Charge Line # RM-156-25 to prevent your battery from being drained down while towing. I do recommend using either the Air Force One # DM26VR if your motor home has actuate brakes or Stay-IN-Play...

  • Parts Needed For Flat Towing a 2006 Jeep Wrangler TJ With Smittybilt Front Bumper 76800
    I reached out to Smittybilt and they informed me the tabs on your bumper can be used for flat towing your 2006 Jeep Wrangler TJ. To do this you will simply add the D-Ring Adapter # RM65FR to the Roadmaster Nighthawk All-Terrain Tow Bar # RM-676. Do note the tow bar needs to stay within 3" of level from your receiver to the front of your Jeep. Here is a list of High-Low adapters you may need if your connection points are not within 3" of each other. 4" Rise/Drop # RM-048-4 6" Rise/Drop...

  • Will The 2-Piece Roadmaster Base Plate Kit # RM-521453-5 Fit a 2016 Jeep Wrangler Unlimited?
    For your 2016 Jeep Wrangler Unlimited you are going to need the Roadmaster Direct-Connect Base Plate Kit # RM-521448-5. The crossbar integrated into this mount is required due to your chassis. On the newer JL Wrangles the Base Plate # RM-521453-5 you found is designed to fit the chassis has more strength and does not need the crossbar. I recommend pairing this with the Roadmaster Nighthawk # RM-676. The Roadmaster Accessory Kit # RM-9284-2, Wiring # HM56200, and Charge Line # RM-156-25...

  • How to Gain Ground Clearance For a Hitch Mounted Cargo Carrier on a 2003 Mitsubishi Outlander
    To resolve your ground clearance issue with your cargo carrier, I would recommend getting a cargo carrier with a rise in the shank like the Curt Cargo Carrier, # C18110. I am not aware of a trailer hitch with a 2 inch receiver that will fit on your 2003 Mitsubishi Outlander. One thing to keep in mind when using a hitch adapter to convert a 2 inch shank to a 1-1/4 inch receiver is that the tongue weight capacity of your trailer hitch will be reduced by 50 percent. Like you stated, I am...

  • Recommended Flat Towing Solution For 2022 Ford Bronco With Modular Bumper and Winch
    I do see the winch and mount you found is for attaching to the Ford Modular bumper on your 2022 Bronco. For this I recommend the Roadmaster Direct-Connect Base Plate Kit # RM92ZR. Roadmaster has one of the best reputations for quality and testing among all the brands we carry. Here is a list of the other components that will be required for flat towing your Bronco.

  • Is There an Option to Lower the Trailer Hitch Receiver for Motorcycle Carrier Use?
    There really isn't an option to lower your hitch 6 inches and carry 400 lb motorcycle with carrier. The Roadmaster Dual Hitch Receiver Adapter, 6" Drop/Rise # RM-077-6 is the strongest option with a 400 lb tongue weight capacity that doesn't account for the weight of the carrier, so is not a working option. Adapters simply are not strong enough for the tongue weight you are seeking. Your best option is to use the Replacement Shank for Gen-Y Adjustable Ball Mount - 2" Hitch - 7-1/2" Drop/Rise...

  • Parts Needed to Flat Tow 1999 Honda CR-V
    A transmission cooler like Derale # D12903 is intended for a vehicle that is doing the work of towing a trailer rather than for a vehicle that is being flat towed. Your 1999 Honda CR-V can be flat towed with all wheels on the ground whether it is has a 5-speed manual transmission or an automatic transmission. The flat towing preparation procedure is slightly different for each type of transmission but in both cases you'll want to ensure the transmission fluid level is full and that you...

  • How to Lower the Connection Point for a Hitch Bike Rack
    I do have an option for you but Curt does not recommend using the Curt Dual 2" Receiver Tube Adapter part # D-192 in the fashion you described. This is also going to be the case for the Malone 2" Dual Purpose Hitch Receiver part # MPG544 as I called them as well. The best option we have for you to lower the connection point that the manufacturer will still warranty is to use the Roadmaster High-Low Adapter part # RM-048-6. This adapter is going to provide a 6" drop but please keep in...

  • Solution for Blue Ox Tow Bar Hitting Pavement on Steep Driveways and Road Dips
    There isn't a wheel or similar product available that is designed to mount to a tow bar like what you have. Your best option to prevent the tow bar from bottoming out is to simply see if a different high-low adapter like # RM-048-6 might give you a tad more rise while still remaining in the "Safe Zone" for the tow bar. You will want the tow bar to still be within the range of 3 inches above or 3 inches below level. This does offer some wiggle room where you can hopefully get a bit more...

  • Recommendation to Raise Mobility Scooter Carrier to Avoid Bottoming Out with 2008 Dodge Caravan
    I have 2 possible solutions for you. First, if the mobility chair footprint is less than 32 inches by 48 inches and weighs under 400 pounds, you could use a different carrier. Take a look at the Pro Series Steel Solo Cargo Carrier and Folding Ramp, # PS10401-10402, for 2 inch trailer hitches. This carrier has a ramp to load the chair and it also has a shank with a 4 inch rise. This keeps the platform a little higher than a straight shank carrier. I have included a link to the installation...

  • Can 2005 Pontiac Vibe Be Flat Towed Behind Motorhome
    I checked the online owner's manual for the 2005 Pontiac Vibe on the GM website and it shows that the front-wheel-drive with manual transaxle CAN be flat towed without need for a transmission lube pump and it can also be towed using a dolly like # RM-2050-1. However, the all-wheel-drive version cannot be flat towed, nor can it be towed with two wheels up on a tow dolly. The basic parts of a flat towing setup include the tow bar, lighting kit and braking system you mentioned, as well as...

  • High - Low Adapter for a 1-1/4 Inch Hitch Opening
    No, I am sorry, but this will not work. First, the RM-048-6 is for towing a vehicle behind a motor home. Every time you add either an adapter or an extender, you reduce your tongue weight by 50 percent. You would need to add both, and with a Class I hitch, the weight of the bike rack, adapter, and extender would be too much for the vehicle. We do offer some great bike racks which are made to attach directly to the vehicle. We also have some 2 bike racks which will fit your 1 1/4 inch...

  • Parts Needed For Flat Towing a 2000 Ford Ranger Behind a Motorhome/RV
    The Curt Tow Bar # C19745 is a universal fit tow bar that is designed to work with vehicles that have a heavy duty front bumper that is rated for towing. If you have this type of aftermarket bumper then you can use it on your 2000 Ford Ranger. I verified the information for towing in the owners manual for your Ranger. For both 2wd and 4x4 models with the automatic transmission if you plan on towing your Ranger further than 50 miles or at a speed greater than 35mph you will need to remove...

  • Parts Needed To Flat Tow a 2017 Jeep Wrangler Lifted With Aftermarket Bumper Having 3/4" Wide D-Ring
    First you will want to verify with your aftermarket bumper manufacturer to ensure it is rated for flat towing use. As long as your bumper is rated for towing you can attach the 3/4" D-Ring Adapters # RM-035 to the Roadmaster Nighthawk Tow Bar # RM-676. These adapters will fit a 3/4" wide D-Ring with either a 7/8" or 1" diameter mounting pin. With your 2017 Jeep Wrangler being lifted you will likely need one of the High-Low adapters to keep the tow bars within 3" of level from your motorhome...

They could not provide me with either so you will want to first verify if your bumper is safe for flat towing and the dimensions of the mounting tabs. We have the 1" Wide # RM-035-1 and 3/4" Wide # RM-035 adapters which are designed to replace the ends on the Roadmaster tow bars like the Nighthawk # RM-676. Both the adapters above...

  • Adapter to Lower Height of Hitch-Mounted Cargo Carrier
    A 2-inch high/low hitch adapter like Roadmaster # RM-048-6 will provide 6-inches of drop (or rise) to allow your 2-inch cargo carrier to be lower than hitch height. Part # RM-048-4 will give you 4-inches of drop (or rise). Do please note three important considerations when using either of these adapters. These have a 400-lb tongue weight rating, which means that no matter how much capacity your hitch may have, the combined weight of the cargo carrier and what you load onto it cannot exceed...

  • Do I Need a High Low Adapter to Flat Tow a 2024 Chevy Equinox RS?
    No, you shouldn't need one. When the Roadmaster Direct-Connect Base Plate Kit item # RM-523193-5 is installed on the 2024 Chevy Equinox RS it measures 15-3/4" from the ground to the center of the arms. In order to be considered level the tow bar needs to be within 3" of the base plate arms. I checked Roadmaster's website and didn't see any adapters for a flag pole or Starlink mount. The best I can offer is the Camco Hitch-Mounted Flagpole Holder for 2" Hitch Receivers item # CAM51611. Here...

With these mounts you will not need to use a crossbar and will be able to connect directly to the Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar # RM-422. The tow bars have a rating of 10,000 lbs and are non binding tow bars that make disconnecting your vehicle easier. Channels are added to the tow...
