To The International ProStar Drivers: What Do You Think Of Your Truck..?

I'm going to school at a company that is getting a lot of new International ProStars. For all you drivers out there driving one or who have seen one, what do you think of them? How much room do they have? How well do they drive? If you had the choice, would you keep that truck or switch to something different? How about the gas mileage? Thanks for the input!
