ALL are suitable for work, but it could come down to the type of work you do. None will work as hard as a Japanese one-tonner. If you don't need to carry heavy loads, the Falcon may well do the job. The XH will carry more than the XD and XF in its one-tonne guise, so that may be worth a look. XD and XF Falcons are getting long in the tooth and will be well past their use-by date. In utes you need to look for damage to the body. The condition of the inner tray is a giveaway to its previous life. Also, check early Falcon utes for rust.
