That sounds like a fantastic modification to the Oxbo Pack in FS25! Changing the vehicle and rim colors can really give the equipment a fresh look and make it stand out in the field. Increasing the speed on the field is a great way to improve efficiency during harvesting, allowing you to cover more ground in less time. Additionally, choosing different bunker capacities can provide you with more flexibility in managing your harvest and storage needs. Overall, these modifications seem to enhance the gameplay experience and offer a more customized and enjoyable farming experience. Great job on the Oxbo Pack v1.0!
