• Will Kuat Bike Rack Fit with Roadmaster 10-1/4 High-Low Adapter
  I was able to test fit the Roadmaster High-Low Adapter # RM-048-10 you referenced with the Kuat NV 2.0 2-Bike Platform Rack # NV22G and found that the square receiver for the Kuat rack had no problem installing in the Roadmaster high-low adapter so you will be just fine! Please keep in mind that when using any adapter or extender the tongue weight rating of your hitch is reduced by 50%. I do recommend using the Quiet Hitch # RM-061 to help minimize the movement of the adapter in your...

• Troubleshooting Flat Tires When Towing Mini Cooper With 2011 Holiday Rambler
  First, before flat towing your 2011 Mini Cooper, be sure the tires are filled to the recommended psi and in good condition. More importantly, be certain your steering column is not locked; if your tires are unable to turn they would wear out quickly. If you think your safety cables may be an issue, and yours are shorter than 7', an option would be the Blue Ox Blue Ox 7' Safety Cables # BX88197. Another thing you could do is add an anti-rattle device such as the Blue Ox Hitch Receiver...

• How to Tow a Lifted Jeep Level Behind a Motorhome
  You will absolutely need to use a high-low adapter in order to bring the connection point of the towbar more parallel with the trailer hitch receiver. The recommended distance is +/- 3" but the closer you are the better the vehicle will tow. For this, I recommend using the Roadmaster High-Low Adapter part # RM-048-10 which offers up to a 10-1/4" rise/drop. Please note that the trailer hitch side is measured using the center of the receiver tube. I have attached a review video for you...

• Measuring for High Low Adapter to Flat Tow Vehicle Behind Motorhome
  The longest adapter we carry is the Roadmaster High-Low Adapter - 2" Hitches - 10-1/4" Rise/Drop - 10K GTW, 400 lbs TW # RM-048-10. I don't know if you measured from the top of the receiver opening, but this will get you 10-1/4 inches of drop from the center of the receiver tube opening. Your tow bar can have a 3 inch drop but anything further than that isn't safe due to road bumps. Make sure you are measuring from the ground to the center of your hitch receiver and from the ground...

It will take just a couple of steps to determine which adapter is right for you. First we will start determining the rise that is needed. Since you want the setup as level as possible, you will want to measure the height from the center of your hitch pin hole on the RV to the ground and then the distance from the center of...

• Hitch High/Low Adapter for Better Ground Clearance When Using Cargo Carrier
  Roadmaster High-Low Adapter # RM-048-10 for 2-inch hitches will give your hitch-mount cargo carrier 10-1/4-inches of height gain for better ground clearance. It will also reduce your hitch capacity by 50-percent, as do all such adapters/extenders. This loss of hitch capacity results from the change in geometry, which moves the carrier's weight load further away from the hitch itself. You'll need to make sure the combined weight of the carrier and its loaded cargo does not exceed half of...

• How Far Off Level Can a Tow Bar Be When Flat Towing a Vehicle Behind an RV
  For most tow bars the "safe zone" between the RV and the toad is 3 inches off level. The height is measured from the ground to the center of the receiver opening and to the center of the base plate. If you find that your set up is outside of the safe zone then there are high/low adapters you can use to compensate for the height difference. I have included a link to our help article explaining the adapters and safe zone as well as a link to our selection of high/low adapters.

• Correct Use of Roadmaster 10 Inch High-Low Hitch Adapter
  Tow bars are used behind motorhomes or trucks to tow a vehicle. The Roadmaster 10 inch High - Low Hitch Adapter, part number RM-048-10, is not designed to have tongue weight applied to it like when towing a boat trailer, utility trailer or camper. This adapter is designed for applications where the towed vehicle is resting on its own four wheels and being pulled by another vehicle with a tow bar. We do have ball mounts with a 10 inch drop or more and adjustable draw bars that will allow...

• Recommended High-Low Adapter with 14 Inch Rise/Drop
  As you mentioned in your question, the largest rise/drop high-low adapter we have available is the Roadmaster High-Low Adapter # RM-048-10, which provides a 10-1/4 inch rise/drop measurement. As you also referenced, the goal is to raise or lower the height of your tow bar to the "Safe Zone", which ranges from 3 inches above level to 3 inches below level. Obviously, you will want the tow bar to be as level as possible, but as long as you are inside this zone, the tow bar will be within its...

• Recommended High/Low Adapter for Flat Towing a Jeep Behind a Motorhome
  It sounds like the problem you are trying to fix is that your tow bar does not sit level while your Jeep is being flat towed. According to Blue Ox and Roadmaster, most tow bars can be off-level by 3 inches at the base plates but the closer to level you are the better it will be. Based on the measurements you provided, I recommend using the High/Low adapter # RM-048-10. This adapter would place the tow bar's attachment to the hitch only 1/4 of an inch from level which will be great...

• Should Trailer High Low Adapter Be Used to Level a Trailer
  Instead of a hi low adapter you would just want to go with a ball mount that will allow your trailer to be towed as level as possible. Adapters cut the capacity of the hitch they are installed in by 50 percent. I attached an FAQ that details how to pick out the correct ball mount. Picking out the correct ball mount will allow your trailer to sit as level as possible. Basically you will first measure the height from the ground to the top of the receiver opening on the hitch while on level...

• Highest Amount of Rise for a High/Low Hitch Adapter for Use with Tow Bar
  When using a tow bar to pull your modified 2016 Jeep Wrangler Unlimited you will need a high/low adapter to reduce the height difference between it and the RV. The greatest amount of rise available comes from the two items shown on the linked page, Roadmaster # RM-048-10 and Blue Ox # BX88132. There is no adapter with 15-inches of rise. Generally tow bar makers recommend no more than 3-inches above or below level for either end of the tow bar, so you may need to re-position your D-rings...

• Solution to Allow a Cargo Carrier be Carried Higher than Stock Hitch Height
  Because the high/low adapters like the part # RM-048-10 that you referenced are only designed for flat-towing purposes I cannot recommend you use one with your cargo carrier. The best recommendation I could make for you would be to use a Curt Multipurpose Ball Mount # D210. This will give you about 4-1/2 inches of additional rise for your cargo carrier.

• High Low Adapter Recommendation to Give Thule T2 Bike Rack More Ground Clearance
  I believe I have a solution for you, but the part # RM-076 that you referenced only has a 100 lbs capacity so it wouldn't be rated high enough. Instead the part # RM-048-10 would give you up to 10 inches of rise and has a 400 lb tongue weight capacity. You should note that using adapters like this does cut the capacity of the hitch by 50 percent so you would need to verify that your hitch would have the capacity. To minimize movement you may also want the part # RM-061 that locks...

• Trailer Hitch Riser for a Class I Trailer Hitch on a 2016 Honda Accord Sedan
  The best option that I can offer that is also compatible with the Class I trailer hitch on your 2016 Honda Accord is the Brophy adapter # HT5R. It will provide an additional 5 inches of rise. It fits the 1-1/4 hitch you have but the upper receiver is for 2 inch accessories. Please note that the use of this adapter will reduce the tongue weight capacity of the trailer hitch by 50 percent. That means that the weight of the Cart Caddie, loaded and ready to go, cannot exceed 100 pounds.

• Making it Easier to Load Scooter on Carrier on an RV with Trailer Hitch that is High Off the Ground
  High/low adapter # RM-048-10 can be used for hitch mounted accessories such as a scooter carrier. However the use of an adapter reduces the tongue weight capacity of the trailer hitch by 50 percent. It also moves the accessory further away from the hitch receiver resulting in extra stress on the hitch (which is the reason the tongue weight capacity is reduced). Most hitches on RVs are rated for 500 pounds tongue weight meaning at 50 percent reduction it is only rated for 250 pounds....

• Does Roadmaster High Low Adapter Change Angle of Hitch Tube for Carrying Bike Rack
  The angle of the hitch tube on the Roadmaster High Low Adapter part # RM-048-10 will match the angle of the hitch tube it is installed in. Your bike rack would not angle down unless your hitch happened to be angled down. You should note that adapter will cut the capacity of the hitch it is installed in by 50 percent

• How Does a High-Low Adapter Affect Trailer Hitch Weight Rating for Flat Towing
  The high-low adapters that are made more for flat towing setups instead of towing a trailer, like the Roadmaster # RM-048-10 which has a 10-1/4" rise/drop, actually only decrease the tongue weight rating of your trailer hitch when you use it for an accessory like a bike rack. Since you will be using this adapter to flat tow your Ford Focus the weight rating of your trailer hitch won't be affected because your Focus completely supports itself. The reason why extenders reduce weight ratings...

• How to Measure for the Correct High-Low Tow Bar Adapter to Flat Tow a 2003 Saturn L300
  You want the tow bar to be as level as possible to tow the vehicle safely. You will need to measure from the ground to the bottom of the base plate arms that attach to the tow bar (when parked on level ground). Then measure from the ground to the top of the receiver opening on the RV. If the RV receiver is higher the difference is the amount of drop you will need. I have included a link to the various adapters we have.

  In order to choose the correct high-low adapter to flat tow your Fiat, you will need to take some measurements. With your RV and Fiat on level ground, measure from the ground to the center of your hitch receiver. Then measure from the ground to the center of the base plates on your Fiat. If the trailer hitch is higher, you will need a drop in that amount. If your Fiat is higher you will need a rise in that amount. I've added a link to a help article on measuring high-low adapters as...

• Will The Roadmaster High-Low Hitch Adapter, # RM-048-10, Work On A Blue Ox Aladdin Tow Bar
  The Roadmaster High-Low Hitch Adapter, # RM-048-10, is for a 2 inch hitch receiver opening. If the hitch on your motorhome is 2 inches and the Blue Ox tow bar has a 2 inch shank then it will work. I looked up the Blue Ox Aladdin tow bar and it shows the standard tow bar as having a 2 inch shank that goes into a 2 inch receiver. If you have the standard tow bar with the 2 inch shank then this adapter will work with your tow bar. This adapter has a 10 inch drop and can only be used...

• Adjustable Ball Mount to Allow Motor Home to Pull Vehicle on a Tow Dolly
  It sounds like by "hitch" you mean a ball mount with 10-inches of height drop. The part you referenced, Roadmaster High-Low Hitch Adapter # RM-048-10, does provide this amount of drop but is intended only for applications that use tow bars to flat tow a vehicle. It is not suitable for use with a hitch-mount tow dolly like the Roadmaster # RM-2000-1, if that is what you have. We do offer a fixed ball mount from Convert-A-Ball Ball, their # AMSC10, that provides 10-inches of drop (or 8-3/4-inches...

• Which High-Low Adapter Should be Used With 2017 Thor Towing 2017 Chevy Spark?
  To determine the correct high-low adapter you are going to need to know where the base plates on your 2017 Chevy Spark will be. If you do not have the base plates yet they do look to be very close in height to the fog lights and if you measure from the middle of those lights to the ground that will give you an approximation of the correct amount of drop you'll need instead of a blind guess. I have added a link to a help article on high-low adapters I recommend taking a look at, as well...

• Can Roadmaster High-Low Hitch Adapter # RM-048-10 be Used When Towing Car Dolly
  If you are looking to lower the hitch height of your tow vehicle by 10" in order to tow your 2015 Hyundai Elantra with a tow dolly, I recommend taking a look at the Cushioned Ball Mount for 2" Hitches, # AMSC10. This ball mount was designed with towing in mind and offers a tongue weight capacity of 2,000 lbs and a towing capacity of 10,000 lbs. The Roadmaster High-Low Hitch Adapter, # RM-048-10, was designed for use with tow bars and is not for use with any style of trailer or car dolly. The...

• Could Roadmaster High-Low Adapter # RM-048-10 be Used with Swagman Bike Rack
  The part # RM-048-10 can be used with a bike rack but you should note that it cuts the capacity of the hitch it is installed by 50 percent plus it weighs 24 lbs. So you'd need a hitch capacity of at least 288 lbs to carry 120 lbs of bike and bike rack.
