Aftermath
By moving the Dust Runner over to a non-berth area of the starport, you avoid the berthing fees, but it wasn't really being enforced anyway as the point of them was to get ships to move it and out quickly. With so little traffic coming in, the berths weren't really needed.
Additionally, due to the war, all mortgage payments were suspended for the duration because the banks realized you couldn't earn any income if you couldn't leave the planet. And what would the bank do with all these impounded ships, sitting there requiring the bank to pay berthing fees and maintenance.
Also, for the above reason (and a few others), you were able to negotiate an impressive deal to swap the two ships. Government subsidizing of lost revenues and such enabled you to swap the two ships through a broker who did some financial prestidigitation to reduce the owned mortgages. He could quite get rid of all of it, but the Darrian Far Trader has a lot of remaining value.
Clive had originally quote a 100MCr price for the ship, but he'd set that price to scare away anyone who wasn't really interested. The actual book value of the trader was around 68MCr.
So, at the end of the 3 years, you've managed to get the engines fixed... since there wasn't any great rush to do that and most of the engineers had their hands full with the war effort, they could work on it in their spare time... at a reduced rate.
You've done enough odd jobs to keep up on the maintenance.
You are now down to a crew of 7: Luise, Arc, Harry, IM, Kraig, Roland and Steve.
Once given the okay, you've got about a month before departure to work on any last minute details... such as buy cargo, if that's what you want.
You also still have a standing offer to move the Baron off world.
