I was accepted to RVU and just interviewed at TUN (am really hoping for an acceptance there). For me personally, I would pick TUN for the rotation sites alone. You will almost certainly have to move for 3rd and 4th year at RVU and the rotations are not at teaching hospitals. There are tons of rotation sites available to the TUN students, and they are adding more residencies to the southern nevada area in the next year or two. Also, TUN is switching their curriculum to systems based, which is the same one RVU has.
