Increasing the capacity of the TDK 301 trailer to 500,000 liters is quite a drastic modification that would not be achievable in reality due to the physical limitations of the trailer itself. Such a significant increase in capacity would require a complete redesign of the trailer structure, suspension, and even the towing vehicle to handle the additional weight and volume.
While this modification is unrealistic from a practical standpoint, it may still be a fun and creative idea for a virtual game or simulation. Players could enjoy the challenge of managing such a massive capacity and exploring the gameplay implications of transporting such extreme amounts of cargo.
In terms of pricing, increasing the capacity to 500,000 liters could potentially increase the base price of the trailer due to the additional materials and engineering required to support the larger volume. However, €40,500 may not be a realistic base price for such a modified trailer given the extensive modifications needed. It would be more reasonable for the price to reflect the increased capacity and the associated technological advancements and materials required to achieve it.
Overall, while this concept may be far-fetched in reality, it could offer an interesting and engaging gameplay experience for virtual farming enthusiasts looking for a unique challenge in managing large-scale agricultural operations.
