Zero benefit. People with poor decision-making abilities have been doing this for decades.
First of all I want to stress that you should always leave a safe distance of at least 2 seconds and make sure you can see at leas one of the truckers mirrors. If you can see the mirrors the trucker can see a good part of your car.

One problem with drafting a square box truck is the buffeting in the wake. The vortices disrupt the wake for several seconds behind the truck. Fairings pretty much eliminate that and leave a cleanish wake which is much better for drafting, even if if reduces overall drag.

Even at a safe distance the effect is noticeable, and when it is busy the mass of traffic will draw air along like a conveyor belt in which wake effects remain stronger at distance, especially on windless days or in tunnels etc.

For confirmation go to people just like you.
For education go to people unlike yourself.
