Read your blog post you referenced about reaction time. My concern is not with the truck braking so much as the truck seeing something in the road (like a tire tread.) He's high enough to clear it, but you may not be, and might sustain some damage.
If I did a lot of cross-country driving (where it would make sense to make the effort to draft a lot), I might get a CB and ask ahead of time if I can draft. Some truckers are more amenable to this than others, but all appreciate being asked first.
That said, I do draft at 75-150 feet (depending on speed) during my commute, for 2-5 minutes at a time.
