Sometimes I am amazed at the conversations on this list.

1.) 2 inches is drafting in a NASCAR race. A semi has a much bigger
cone of influence so two van lengths might well be within the draft
zone.
2.) Mr. Bawden has the most legitimate concerns. What a semi can
straddle is much larger than what you can straddle.
3.) If you are paying attention, you will not end up as a rear bumper
ornament on a semi. Stopping distance for a 40,000 lb truck is a bit
longer than a 4,000 lb van.

I have done it (in a 65 Chevy van) but I don't recommend it.

Where ever you are, there you be. Unless you're driving my van, in
which case, you ain't got there yet.
