I just took at look at my original copy of Book 2 (eleventh printing)
and I noticed something... Tech levels aren't mentioned at all in reference
to drives. Not at all. The only mention of tech level I saw in Book 2 was
for *drugs* (what *they're* doing in Book 2: Starships, I don't know).

I don't know about that... How about the *size* of the drive? The
higher the tech level, the smaller the individual components are, and the
more room you have for goodies. At least, that's how it was in High
Guard. I don't have that much experience with MegaTraveller's craft
design system (yet). A Jump 1 drive took less of a percentage of the total
volume of the ship at TL15 than at TL9, as I recall.

Didn't the original Xboat design *not* have a power plant?

Yup. At least one Rift-crossing route can be done by Jump 5 ships. If
a ship can cross eight parsecs on one load of fuel (even if it takes two
weeks), then it should be able to cross the Rift without too much trouble.
