2003 ford mustang suspension problems

My dad just purchased a 2003 ford ranger 2WD 3.0V6. the only problem is that the truck leans to the drivers side by about an inch, no matter where we measure from. We took it back to the dealer and the "gentleman" that helped us was, lets just say, not very helpful. If anyone else has any experience in this area i would appreciate any comments, thank you.

Thats actually fairly common to rangers. The gas tank & extra weight under hood (battery, etc) & the driver weight tend to cause this over time. Usually only on older rangers though. New shocks might help problem for a while.

I see how it could happen over time, but the wierd part is that it was like that from the factory.
