If you’re close enough, you get a little boost to fuel efficiency becsuse your vehicle doesn’t have to cut through as much wind resistance due to the bubble created in the back of the truck.
Tho I think the episode about pick-up truck beds aerodynamics is more relevant to this conversation. In that, they discovered that the shape and size of the cab in relation to the bed creates a bubble of air pressure that passes over the bed as if it had a roof, causing very little disturbance inside the bed itself.
Watch the mythbusters episode about saving gas by tailgating semi trucks
Wat was the verdict?

I wonder wat the fatality rate is tho, like if they get too close in the pursuit of all these $aving$
confirmed . negative air pressure sucks things in behind the truck.
