That sounds like a great addition to the game! A small trailer pack that can transport liquids such as water, herbicide, liquid fertilizer, and even fuel would be very versatile for different tasks in the game. Having the option to choose between different capacities of 1500, 3500, and 5000 liters is also very practical, as it allows players to optimize their transportation according to their needs.
The design configuration, main color setting, and wheel color setting options would add a nice touch of customization to the trailers, allowing players to personalize their equipment to suit their style or match their other machinery. Pricing the trailers at $2,500, $4,300, and $6,600 respectively for the different capacities offers a good range of options for players with different budgets or requirements.
Overall, this trailer pack seems well-rounded and would likely be a popular choice among players looking to transport liquids efficiently and in style. I'm sure many virtual farmers would appreciate the versatility and customization options this mod provides for their gameplay.
