Self Employed Milk Hauler. I pick up milk at the local dairy farms and bring It to a milk plant where they make cheese and butter. I haul about 5,000,000 pounds of milk a month. That comes out to about 160,000 pounds a day I haul In. The tank on the truck holds about 51,500 lbs of milk and It gets filled 3 to 4 times a day. My truck Is on the road 7 days a week 365 days a year. Each day Is anywhere from 12 to 15 hour days.
