Well I just stared working for ups 2 years ago. And been driving for a year now, just wondering I see alot of guys tap there truck batteries to plug in -Fans -Radio -GPS -Phone Chargers And also see a few ppl bringing large duffle bags to work with all kinds of stuff like flashlights, paper towel, spare set of clothes. And of course I see alot of ice chest, 5 gallon water coolers, lunch bags, bla bla. Anyway I just wanted to know what exactly to you guys think would be worth it to bring for a 10-12 hour shift at UPS. In my own personal experience I would only bring what I could carry on me at all times and an Ice Chest. Ive tried those other things and its nice, but most the time its just a big pain in the arse. This is my set up. Big Ice Chest for waters and lunch, flashlight, pocket GPS(instead of using a map), flashlight, small bag with infonotice, COD invelopes, pens, asprin, etc, cell phone.
