We found an interesting discrepancy/errata:
One of my players went and bought the core rulebook in Minneapolis/St. Paul (I bought mine in Portland, OR). His rulebook lists the fuel capacity for a Scout ship as 40 tons, mine lists it as 34 tons. We examined each book and could not determine any difference w.r.t. printing version.
Weird. Another player's book, purchased via Amazon, matched mine.
We decided that the scout vessel had a collapsable fuel blivot that converted cargo space to fuel storage.
