For Fords try this in addition to Autocheck and CARFAX.
Go to a Ford dealer's service or parts department and see if they will run you a free "OASIS" report on the Ford truck.
As I recall, the OASIS report gives a history of warranty recalls for the vehicle model in question and also, a history of warranty related services that were performed on the vehicle you are looking at.
Note: I have been hearing lately also, that Autocheck is actually better and more accurate than CARFAX now.
