1. Go to the truck depot at chop shop and start press e on the NPC out front of chop shop.
2. Spawn the tuck Via the NPC
3. Get into the truck and drive into the hovering words that say "Trailer Spawn"
4. Reverse into the trailer that spawns and it will eventually latch on
5. On the top left corner of your screen it will say where your destination is
6. Drive realistically to that location (Following all speed limits and Signs)
7. Once you arrive to that destination there will be a drop off point there.
8. Reverse or drive the trailer into that point and there you go you have just made 5+ grand
Hope this helps guys,
