Liquid cargo in Farming Simulator 2019 requires a special approach. It is best to transport them in special tank barrels.

So that you understand what we are talking about, we publish a semi-trailer mod for transporting liquids. There are 3 configurations available, each of them has its own task:

Tanker truck. The name speaks for itself, in this barrel you will transport fuel. Designed for various industries, performs refueling of equipment;
Milk truck. Performs transportation of water and milk, also suitable for a variety of facilities in FS 2019;
Station wagon. Suitable for transporting any liquids.
For each barrel from FS 2019, a choice of the main color is available. You can apply inscriptions, change their color. During operation, the tank wears out and gets dirty. Oddly enough, but the barrel is sold in the category "Animals". The price is more than loyal - 1300 euros.
