The Mercedes-Benz R-Class has a maximum braked towing capacity of 3500 lbs. The maximum towing capacity drops down to 1650 lbs upon carrying unbraked loads. The maximum tongue load for the R-Class is about 165 lbs.
However, the manufacturer states that the tongue weight should not drop below 110 lbs as such a low tongue weight could cause a trailer to come loose from the vehicle when it is being towed.

Towing with the Mercedes Benz R-Class
Mercedes-Benz has designed this vehicle for towing, fitting it with the necessary tech and features that would help it in overcoming the rigors of towing. The R-Class is fitted with a trailer coupling with the necessary wiring that would allow it to power the trailer’s brakes and lights. To relieve the engine of the R-Class from the increased heat generation that is faced during towing, Mercedes-Benz implemented an appropriate engine cooling system for the vehicle.
The rear-view camera has a special trailer mode, which provides guidelines on the screen to aid in connecting a trailer to the trailer coupling of the vehicle while allowing close monitoring of the trailer hitch.
Lastly, Mercedes-Benz has implemented the ESP Electronic Stabilization program in the R-Class to overcome swerving when the vehicle enters a vehicle/trailer combination. The program utilizes sensors mounted on the vehicle to detect swerving of a trailer and stabilize the motion by applying the left and right brakes alternatively. The program kicks in automatically above speeds of 40 mph
The Mercedes-Benz R-Class is a full-size 5-door MPV built by German automobile manufacturer Mercedes-Benz. It was introduced at the 2005 New York International Auto Show for the model year 2006.
However, the R-Class was discontinued in 2012 for the North American market and in 2016 for the remainder of the world due to poor sales. The latest models available for the R-Class in the North American market were the R350 4MATIC and the R350 BlueTEC 4MATIC.
To summarize, the Mercedes-Benz R-Class was a full-size MPV that was discontinued in 2013 for the North American markets due to poor sales. The R-Class was able to tow a maximum braked capacity of 3500 lbs thanks to the detailed vehicle designing by Mercedes-Benz.
