Ok first post here, so let me know if I'm doing something wrong:
First of all: There would be two types of vehicles added: one for land (similar to a car hauler), and one for space.
Second thing: All 'prices' I state are just ideas for what I think would be fair and/or balanced.
Land:
Small Vehicle Carrier: Can transport 2 tractors(with 3 trailers each),4 small rovers, or 2 medium rovers. Would cost similar to a large rover.
Medium Vehicle Carrier: Can transport 4 tractors(with 3 trailers each), 8 small rovers, or 4 medium rovers. Would cost 2-4x as much as the large ro
