Towing question

Once you have read and understand what every one on this forum is saying and still have concerns, contact Mike Cannon--(503) 936-1565 at Roadmaster. He is the designer of all of Roadmaster's towing equipment and would be the expert. He normally is really responsive and even monitors this forum.

Make sure it is really 24" to the receiver.

The long rear overhangs make the measurement deceptive. I have a barely perceptible slope on my driveway, but when I measure the height of the hitch in the drive, it measures 6" higher than it measures on level ground. Based on my measurement in the driveway, I put on a 2-inch drop to get "level" with the baseplate of my truck, only to eventually discover that the truck was 1 to 1 1/2 inches high on the road, which was causing me handling problems when braking in turns.

Towbar should never be high at the towed vehicle end, for handling, even if the towbar manufacturer allows it. You don't want the towed vehicle lifting its end of the towbar.

Butch, You'll be putting supplemental braking on this new toad, correct?
I'm wondering: Does the motorhome warning about drop adapters take in ALL towing, or is it aimed mostly at Trailers? I ask because trailers usually need 7-10% of their loaded weight on the Hitch Ball. A towbar, in contrast, applies more like a couple dozen pounds. I realize that accelerating and stopping also stress the hitch and a drop adapter changes the leverage on it. You won't have but so much acceleration, and a supplemental braking system will reduce the stopping force in the hitch area. Also, a towed car won't produce the bucking kind of action over bumps and dips that a trailer can.
In summary, I don't think it would be a problem to use enough drop to get into the towbar's leveling range if the car isn't overweight and you use supplemental braking.
But get a GOOD Drop Adapter like this 8" Roadmaster

Not a cheapie like this

This exact one might be OK but some don't have a corner gusset between drop and drawbar and they've been known to fail at that weld after a few thousand miles of use.
Let's see what other Sprinter owners say...

Are you sure your hitch is 24" off the ground. That seems awfully high. Make sure you are on level ground when checking it's height. Most hitches are 16" to 19" off the ground.
