The trailer wheels can be out of alignment or it could be loaded weird.
What is the truck make, and which way is it pulling? Is it pulling with a trailer, without, or both? Does it pull on all roads, or just on the Interstate? How is the tire wear? What's the tire inflation? How many times can you turn the steering wheel from full left to full right?

What would cause a truck or something I'm doing to, to not keep a straight line when you grab the wheel but when I let up on the wheel is seems to track straight.
Are you inadvertently pulling one way or the other? If it tracks straight when you let go but not when you hold it it has to be you no?
It's a Kenworth. You have turn the wheel to the right slightly.

The truck should have a slight pull to the right. If you're driving straight and let go of the wheel, it should slowly go to the right. This pulls the truck off the road if something happens to the driver.
The reason it may be pulling is because of the front suspension. It is assembled at the factory with positive camber of from four to six degrees at the factory. The actual reason for this is said to offset the engine torque.
It is not a safety feature to guide you off the road, nor will it be caused by the way a trailer is loaded.
If the alignment, tire condition and inflation, and other suspension components are correct and in good condition, it will be something you will need to accept as a company driver. If you are experiencing abnormal tire wear or pronounced steering wheel vibrations , those causes will need to be addressed.
