Out of Chevy, Dodge and Ford which brand of truck is the least reliable? - 1

Reliable is a subjective term. Are you talking over 5 years or 20? Are you talking will it run or will it rust? Maybe you mean which one is most forgiving of lapses in maintenance.

Having worked for all three (and more) badges in the Warranty Claims Administration, I can firmly say NONE.
They (and others) all have about the same chance of repair.
Individual vehicles may be lemons, or prone to lack of reliability, (mostly due to improper maintenance), but overall they should be the same.
