Far enough back to see the truck drivers mirrors on both sides at all times, then, yes there is some benefit which makes "drafting" worthwhile. But not any closer.

The second benefit is that other traffic will want to flow around the unit of "you" and the truck as the truck is seen as being the obstacle. The occasional other driver will insert himself, but not often enough to worry over. IOW, let the truck be the front door and be aware he'll slow on grades. . so "you" as the back door will be managing the overtaking & passing traffic on four-laners to the left lane. Done well this will speed them all around faster and make for fewer driver inputs to each vehicle in re traffic concerns.

So that 14-mph reduction is earned without causing the truck driver to feel there's a problem riding his tail on the one hand, and any skill application to move others around more quickly benefits both on the other. This would be win-win, versus the pure-D bull**** of close drafting where there is no benefit to either party worthy of the name.
