I just got back from a trip to Tucson. As indicated, basically the same as other RJ's. I flew on SkyWest last week as well from RNO-SFO on a CR7 and it seemed about the same. If you have flown in a CR2 before it will be better than that. The food service was Granola Bar on a morning flight, and SunChips or Fritos on the return. If your beverage selection is in a can (everything but H2O) you will get the whole can. As with F9, they use Pepsi products.
Also on a RJ item, the small addition at the end of Concourse A for additional seating should be done soon.
