Love the build. I'm just sorry I didn't start following it sooner. About the license, here in Florida there are many different ones and the regulations are a nightmare to follow on your own. What I finally did was call up the local health inspector, told them what I wanted to do, and asked exactly what I needed as far as my trailer setup as well as licensing. They were incredibly helpful and it turned out that I didn't need nearly as much as I thought. I would recommend you start with your local health inspectors office. I would imagine they would be all too happy to help you make sure you are legal and safe. After all, they will be the one's inspecting your rig. Hope this saves you some headaches. Keep up the good work!!
