I bought one from some guy who claimed it was the software used by dealers.

It was actually a bootleg copy of one of the Mitchell CD's with a warez
crack to override the copyright protection, all burned onto a CDR with a
paper label he printed on his home printer. It didn't even install
correctly. Virtually ALL the ebay sellers selling manuals are selling
stolen software and ebay does nothing about it.

You might find a PDF file for sale there too that may or may not be
pirated, but is more often than not just a scan of a manual like a
Claytons or Haynes. Read the seller's feedback before you buy. You can
select 'view 200 on a page' at the bottom of the page in their feedback
ratings. Scroll quickly through the page to find the red marks. If they
mention things like stolen, bootleg, pirated or anything like that,
avoid it.

Your truck is new enough that there are tons of honest resources for it
at any auto parts store for a fairly low price. If it's not for sale at
Kragen, Autozone or NAPA but IS all over ebay, it's probably stolen.
Ebay sellers don't have 'exclusive buying rights' of anything. You don't
think the big chains would turn down the chance to sell $5 or $10 CDs of
complete service manuals if they were legal copies, do you? They'd make
a fortune if it were legit.

When I asked the seller about what they sold me, they told me to ship it
back and they'd give me a refund. I said it wasn't worth anything since
it was stolen and didn't even work and they then threatened me. If
you're willing to risk a virus to get pirated or stolen software for
cheap (that you can download yourself from the warez newsgroups) go for
it, but you might as well go to the warez groups and do it yourself and
save the postage. Real software like Mitchell costs hundreds of dollars.
If it's $10 software that they say is the "same software the dealer's
use", it's probably cracked or stolen software copied onto a CDR. Ask
the seller directly if it's Mitchell software they're offering for $5 or
$10.

Good luck,

I have bought usede copies of the Ford Service DVDs off Ebay in the past.
They are decent references, but not perfect. Search on Ford Service DVD.
Make sure you are getting the real Ford ones. The recent ones include a date
checking routine and the DVD won't run if they are past the expiration date.
However, you can just set your computer's calander back to a date in the
past and they work fine. Don't pay more  than $25 for one.
