In a region with such gaps, you'd think collapsible tanks would be a given to any crew who want to expand beyond whatever cluster they start in. A jump 1 Free Trader would lose 0.2 dtons cargo space permanently to store a fuel bladder at a cost of Cr.100 and remove 20 out of 81 dtons of cargo space when making a J2 transit. Come on, everyone on the crew cough up Cr.20-25 to buy one before the first flight! For that price, you just beat out any competition who can't justify the cost and the subsector just opened up to you without upping your mortgage or maintenance expenses.
