Meatwad,
Compared to AZ. you have it cheap. My 6 year old trailer cost $365 for one year.. AZ. does it based on the valuation of the vehicle and in the case of commercial vehicles the valuation plus weight. If you buy a top end car or truck figure on spending over $1000.00 easily for the first year. After that it will likely decrease about 10% for a few years.
