美国采购需求：大规模

I'm looking for a large truck that meets specific needs for our upcoming project. Ideally, the truck should have a high payload capacity and excellent durability for transporting heavy goods. It would be great if you could provide details on the options available, including the specs, pricing, and estimated delivery times. Additionally, I'd like to understand the different configurations you offer, such as engine types and any customization options. If possible, please include information about warranties and after-sales service. This will help us make a well-informed decision. Thanks in advance for your prompt response!
