Recommended High-Low Adapter with 14 Inch Rise/Drop

Question:

Hi, Im looking for a 14inch Rise/Drop adapter to use for towing a 2010 Mini Cooper S convertible GVWR 3671 lbs behind a Class A motor home, Blue Ox hitch and base plate mounted on vehicle. According to my research, I could use an 11 inch offset and be within the 3 inch allowance, but my understanding is level is desirable. I see the max offset you offer is 10 1/4 inches. I just spent quite a bit of money having the Blue Ox base plate installed on the Mini, not realizing there could be an issue finding the correct Rise/Drop adapter for my coach, 2005 Fleetwood Fiesta. Your advise would be greatly appreciated. Thanks

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 flexing capabilities.

The 10-1/4 inch rise/drop on the mentioned adapter is going to be the best option for getting as close as possible to the Safe Zone. I recommend verifying the amount of rise/drop you are needing to tow your Mini Cooper. Make sure that the vehicle is parked on level ground and take a measurement from the ground to the center point of the base plates where the tow bar attaches. Then with your RV on level ground, take a measurement from the ground to the center of the trailer hitch receiver.

The difference between these two measurements will indicate the rise or drop you need. I have attached an article on high-low adapters that you might also find helpful.
