I drove semi (still do part time) until recently I started working as a basic. Believe me I've tried a few different coffees and 7-11 is pretty decent. Dunkin Donuts is really my favorite but we don't have any in this part of the country and I usually don't like running the states that have 'em. Flying J truck stops have some good coffee. TA truck stops usually have the worst coffee in the world but you won't sleep for three days. Petro truck stops are right in the middle, decent but not great coffee that keeps you up for a day and a half. I have my own coffee pot in the sleeper on the truck so I can make it to order but right now I have Hills Bros Colombian dark roast.
