Let's see... 2 in the shop, 1 in the camper. Main supplies are in a cabinet in the bathroom.

Suggestion: Mark your calender to check your first aid supplies when you check the smoke alarm batteries. This is a good way to keep up with expired meds and replacements that are needed. When I started this I had some stuff that was 2-3 years out of date. Worse than useless some of that stuff was down right dangerous.

Just my 2-cents on the subject.
