It's very hard to predict what your average will be. First of all the companies you list are all very good reputable ones... but you also need to figure out which ones are single driver user friendly. I have direct experience with only one of those companies (EXPRESS-1) and they were very nice folks to deal with. My advice to you would be to check with the recruiter first. They are provided with printouts that will list average settlements for each type of driver and recent trends. Then go to the closest truck stop and confirm those numbers with one of their drivers. The problem with this is that every driver is a little different. Luck plays a factor and so does experience. You need to know a lot of things that come with experience, like where to sit when empty and what areas to avoid and what areas are hot. In other words, your average mileage won't be the same as an experienced driver in the same class truck. The short answer is there really is no average. Some weeks you may sit most of the week and other weeks you may run till you drop.
