Cons
Some days you don't really get a break and you'll be driving non-stop. They're usually pretty good about giving you time between runs to be able to use the restroom or eat. If you don't put in a lot of availability you might not get a lot of shifts. They like it if you have a good handful of days to work 12+ hours.
