That sounds like a great mod for the Renault M230 in FS25! The features you've listed seem really interesting and add a lot of realism and functionality to the truck. It's nice to see details like the front and rear towbar, hook lift arm animation, and adjustable air suspension. The addition of a stabilizer for loading heavy boxes is a nice touch for those who like to simulate realistic cargo operations in the game.
The dirt effect is always a good addition for immersion. The optional spoiler, headlight protection, and warning strip give players more customization options, which is always appreciated. With 230 hp, a max speed of 90 km/h, and a 300L tank, it sounds like the Renault M230 has a good balance of power and fuel capacity for various tasks in the game.
€35,000 seems like a reasonable price for this truck considering the features it offers. Overall, it sounds like a well-rounded mod that adds some great functionality and customization options to the Renault M230. Great job!
