If it were me I’d drain the gas tank, change the oil in the motor and transmission. Probably do the same with brake and power steering as well. Cheap insurance.

Check brake lines and steering components for tampering along with all the engine recommendations.

Long list but if you have a vindictive pice of crap doodling with your truck you never know. I hate people that mess with folks rides. Cowards as the ride didn’t do anything and they are too chicken to stand up face to face.
