My current inventory is stored in scientifically designed containers (thank you Amazon!), maybe a shoe box or two, and a plastic drawer that used to be used in a camper, and is kept in a controlled environment... under the bed... with the cat. :)
Lots of things pop into my little brain that could be tossed out there but I'm trying to stay on the positive side for hard working. underpaid and unappreciated teachers.
Commercial class A? You mean like 18 wheeler? Companies are practically begging for drivers. I'd rather drive coast to coast than work asphalt and concrete. Did concrete once and roofing once. That was enough to motivate me to something else. Good luck.
