The trailer brake controller is fully integrated into the Expedition's four-wheel, four-sensor, four-channel anti-lock braking system (ABS), and trailer sway control (TSC). Expeditions were offered with an adaptive pneumatic air-ride suspension system with self leveling, payload leveling and trailer load leveling capability from 1997 to 2013. For the 2014 model year, a Nivomat adaptive hydraulic suspension system with self leveling, payload leveling and trailer load leveling replaced the pneumatic system. Both systems can automatically detect when a heavy trailer is coupled, such as a travel trailer, and level the load. Additional ride-height sensors placed on the left and right sides of the SUV also monitor and compensate for any listing caused by improper cargo loading. This keeps the Expedition running straight and level while towing, and at night helps to keep the Expedition's headlamps from blinding oncoming traffic.

With the fourth generation Expedition (2018–present) debuting in 2017, Ford announced that the standard size version will be sold to government agencies and law enforcement, available in the lower based XL trim only.

The FMF Expedition went on sale in the fall of 2007 and production was limited to 650 units total. Reception Motor Trend gave the 2018 Expedition a good review in its February 14, 2018 article, in which they cite the vehicle's “blend of performance (both on- and off-road),
