The main problem I have with Ford's gas trucks is the rough ride. The F250 Superduty we have at work is rather reliable, but damn if it won't jar your teeth out going over the smallest of bumps that my Silverado doesn't even notice...the F-150s I test drove before I brought my Silverado were also similarly rough (that was before the frickin' bailout, by the way, or I would definitley have gone with a Ford)
Their post Powerstroke diesels are pretty sorry...shame.
