Unusually, the XD is available from the factory with a removable in - bed gooseneck hitch for major - league towing
capability (a gooseneck setup is key to taking larger
loads and reducing trailer sway, as it puts tongue
weight directly over the rear axle).
The 68 kilogram (150 pound) occupant
load was chosen because that is the occupant
weight specified for use by the agency for evaluating a vehicle's
load carrying
capability under FMVSS Nos. 110 and 120.
