I do not think this is a 7.3L truck – it’s 10 years old, so that would make it a 2006, with the worrisome engine. Not that this is not a great truck, but as others have mentioned, this model year is not going to have people foaming at the mouth in a bidding war.
Also, for the record, I did just sell a pristine 7.3L F250, 4WD, Lariat edition with 180K miles. I got a good price, but it’s not true that these things sell like gold-plated hot cakes. They are older, they have the miles and people will take that into consideration when making a purchase.
Lots of people approached me about buying the truck, but few of them came with cash-in-hand and no one offered more than $13,000 – which is hardly a fortune. My truck was about as nice as an older truck can be – good paint, no rust anywhere, bed liner, brake controller, 4WD (that works!), running boards, heated seats, a/c, leather interior all in good condition (no tears, clean, etc.).
I only mention this because people can get a little starry-eyed about what their used truck is worth. It’s only worth what a real buyer will pay for it when you sell it.
