It is not easy to fill the order of your clients as most of the time, there isn't enough supply for the orders. If that is the case, then you need to find more suppliers. However, oftentimes, there won't be a problem with that and all you need is to drive your truck to the marketplace. After that, you can collect the money. But, is that easy? No, you might have an accident on the road, especially if you are using a tractor and it has an attached trailer. That is really hard, but that is the situation right now and you don't have much of a choice since you don't have enough money to buy a real truck, yet. Attach the tractor to the trailer, so you can go to the market. Going to the market won't be easy as you might think since there are lots of obstacles along the way. Try not to lose any of the supplies, but if you can't do that, then just try to deliver the needed amount of cargoes. You can't proceed to another level if you can't deliver the right amount of cargoes to the market. The game becomes harder and more challenging as make some progress.
