I use my truck for personal use, and in addition to that, it'll be used for the lawn biz next season. In the past, I never had the business license # posted on the truck, or any form of advertisement (business name, phone#, etc.). I'm not too crazy about having a bunch of decals on my personal truck. I'm wondering if there are any legal issues, or if its just a good idea to have the Lic# on the truck or whay, since I see it a lot. I'm thinking about using magnets, could I put the # on there? Or I was thinking about just putting everything somewhere on the trailer.
