Sunrise Ford Truck that I purchased had hidden severe rust problems. Fort Pierce, Florida

I purchased a used 2000 Ford F-350 from Sunrise Ford in February 2010. I drove approximately 500 miles to get this truck. The rust problem was not disclosed to me. I did not see any rust on the truck or I would not have purchased it. However when I got home to Alabama after driving several hours in the rain I found that the paint was bubbling on the bottom of both sides of the cab near the doors. After a through examination of the entire truck, I found extreme rust on the entire frame, bed (under the bedliner) and numerous place on the cab and wheels.

I have pictures of the rust. Approximate cost of repairs is $7500.00. I am retired and on a fixed income and this situation has caused great financial strain on me and my family.
