Modifying surplus ships.

So the vehicles specified in LBB5 are not the only vehicle you can put in a LBB5 Hull. Then, in that case, the spacecraft design systems (LBB2/LBB5) specify how hulls are done, what additional equipment you put in there is your problem.

The spacecraft design systems (LBB2/LBB5) specify how garages are done, what you park there is your problem. But the garages are slightly different in LBB2 vs. LBB5...

As I said, the far trader from adventure 3.

Quite, the type A2 far trader Empress Nicolle, converted to LBB2'81 by reducing the number of staterooms.

Technically the cargo hold is a component just like any other, the only limitation is that:

LBB2'81, p13:
The total tonnage of the installed fittings cannot exceed the tonnage of the hull.

Having wasted space is perfectly OK, so you have successfully recreated the far trader from A3 with a 61 Dt cargo hold and 1 Dt wasted space. It's not optimal, but that is not problem for the rules.

No, the spacecraft design systems describe, in detail, how you design spacecraft, including e.g. hull, drives, and fuel systems, and the LBB2 and LBB5 systems are different.

They do not describe how you design vehicles.

And the second sentence does include a fuel purifcation plant.
No reason to include it if it can't be installed.

Page 10, Express Boat (type X) (correction, omission and clarification): The Xboat has a custom hull, model
B jump drive and power plant, giving jump-4 capability but no maneuver. Fuel tankage is 54 tons, enough for a single
jump-4 and ten days of operation. The ship has one stateroom for the single crew member; one passenger can be
carried at double occupancy. The cost is MCr 78.3 including discounts. Under strict Book 2 (1981) rules, no 100-ton
design capable of jump-4 is possible; this errata covers all requirements of the design, but comes in at 105 tons.

So, 105 Dt of components in a 100 Dt hull is now RAW?

And the second sentence does include a fuel purifcation plant.
No reason to include it if it can't be installed.

Installing it would invalidate the first sentence, so the tonnage and cost would no longer be correct.

And it would explicitly not be allowed by LBB2 rules.

Installing it wouldn't change the tonnage, see again, the second sentence. Which tells you how much it cost, how much it displaces, and and where it can be installed.

It would be much easier, and clear to say it could not be installed.

but instead, there are installation instructions telling you exactly how it can be done.

and nothing prohibiting it.

Installing it would invalidate the first sentence, so the tonnage and cost would no longer be correct.

Book 2 contains no such prohibition. T&G shows it can be done, and the Errata explains how & does not prohibit it or remove reference to it.

And it would explicitly not be allowed by LBB2 rules.
