FORD 2008 F-150 v.1 - Manual (Page 320)

WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
Ford recommends your vehicle be towed with a wheel lift or flatbed. Do
not tow with a slingbelt. Ford Motor Company has not approved a
slingbelt towing procedure.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
On 4x4 vehicles, it is recommended that your vehicle be towed with a
wheel lift and dollies or flatbed equipment with all the wheels off the
ground.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
