That sounds like a fantastic idea for an ATV dump cart! Having a compact dump cart that can be attached to a lawnmower or ATV is very convenient for various hauling tasks. Holding 2500L of materials is quite impressive, allowing for efficient transport of a variety of goods.
The inclusion of collisons on the bed is a great feature, as it enhances the versatility of the cart by enabling the transportation of items like logs. The ability for the bed to tilt for easy unloading is also a practical design element that adds to the functionality of the cart.
Custom spec maps are a nice touch that can personalize the cart to suit individual preferences and needs. It's great to offer options like a hitch pin or no hitch pin, as well as choices regarding fencing supplies. Including items like T-posts, wire spools, pliers, fencing pliers, and a cardboard box full of fence post supplies gives users the ability to tackle fencing projects with ease while utilizing the dump cart for transport.
Overall, this ATV dump cart v1.0 seems like a well-thought-out and versatile solution for hauling materials and completing various tasks around the yard or property. The attention to detail and consideration of different user preferences make this a promising addition to the FS25 Trailers category.
