You are "tinkeling in the breeze" if the data plate is missing.
Get a replacement data plate and stamp or engrave it, install it, and then get your truck inspected.
If they see it without a data plate the sh#t will hit the fan. It is not your fault as it came like that but it is a felony to remove the VIN plate from the vehicle.
They won't charge you but they will become way way less cooperative when they see that.
Plates are available and not expensive. On average, a new plate and engraving can be as cheap as $45 which is a small price to pay.
I know an engraver here that has done a few data plates that does and excellent job if you don't have one there.
It takes about a week on average as they are busy but worth the wait.

PS: what Kyle said is correct. Texas does keep their vehicles in pretty good shape body wise. The paint can be rougher from the sand blowing but there is virtually no rust in central and west Texas.
