Need help with tire situation PLZ

Here is the scoop. I went and got a wheel alignment done this morning and they notcied something that I have never noticed before. On my right side of the truck from the tire to airdam where the fog lights are is about 1"-1 1/2" gap compared to the left side measured at the same place. has anybody ever noticed this? I was wondering if it is something GM did or is something bent under my truck.

you have an 02? I'll check my 2000, this sounds wierd.

Yes,

I have a 2002 Z71.
