I have tried and can not figure out how to figure this or what method to use.
Here is the scenario.
I buy a old vehicle and film YouTube videos making money outfitting, installing, and reviewing the vehicle modifications with all sorts of equipment such as suspension, engine modifications, custom bumpers, racks anything of the sort. But I film installing/using that stuff. I take the vehicle on trips vlogging the trip and the vehicle and its modification are in use on the video. then I take the vehicle and modifications on private camping trips with family and do not record but use the vehicle and modification for private use are the modifications still a write off based on mileage used? price of the part because it is in a video/videos? Can the vehicle still be used as private and business, business only? Do I deduct the price of the parts based on mileage used for personal and business use?
Also because the part is in a video and YouTube is my business can I write the part off 100%. Then The mileage of the vehicle is a separate deduction divided by business and personal use?
