It was most likely the same exact way when you bought the truck.
The alignment did not change from factory positioning.
It would be interesting to take it to a different dealership and have them "check" the alignment.
Then compare the results,...... money says they will differ.
Tire wear is what and steering wheel feel is what I use to justify an "alignment"
If it drives good and even and tire wear measures good and even,................... its good and even.
