This doesn't seem like the best grid to make a town but I really don't know what else to do. Specially given that the structures have a fall off range and to upgrade they NEED to have the satisfaction meter full.

Also how the fuck do you set up efficient trading routes? The game doesn't give you how long it takes for a round trip, and how fast production is made(I suppose it is 1 equals 1 minute?).
I have my peppers ship trucking around 5 units of peppers, and it seems to mostly bring 2-3 units of peppers per trip.
