The heavy-duty F450 and F550 provide the ultimate in utility, with properly equipped versions rated to tow a maximum of 24,400 pounds--significantly more than their nearest competitors. Both trucks also offer a number of creature comforts, and both maintain a relatively tight turning circle, making them easy to live with both on and off the job. Several trim configurations are available in both 2- and 4-wheel drive, making the F450 and F550 well suited to a variety of heavy-duty tasks.
