I drafted a big truck on I-5 for over a hundred miles late one night on the
way to LA.  1/4 inch throttle pedal opening on my 89 wolfy.

If you have a CB and let the trucker know you want to "park on his bumper"
for a few some will not get upset about doing it.

Best spot is up pretty darn close though better be on the ball the WHOLE
time.
