Vehicle Truck/SUV deduction question

Hello, I am an artist and own a small business where I am the only employee. I'm looking to purchase a truck or SUV to be used 100% for business. I will use it to deliver paintings, transport my booth and art to the art fairs and take it into the woods to get to areas i will be painting. I've read multiple websites that have tried to explain how much I will be able to deduct. The vehicle will cost approximately $35K and I will put about 5K miles on it annually, I'm hoping to get 20 miles per gallon if that helps. It will have my logo on the side if that matters. As for depreciation my guess is it will have a worth of $10k in 5 years. Can someone help me figure out how this works and if its worth it to purchase a vehicle? Thank you
