What kind of "just in case" things do you carry with you while at work? I'm talkin' about everything (batteries, extra oil, spare tires, toilte pper, anti diahreal LOL, fire extinguishers, change of clthes, etc.)? You name it! I am trying to think of everything I could possibly ever need and putting it in my van. What do you carry or even what do you suggest carrying? Remember I'm talkin' about anything and everything.....looking forward to your answers!
