I'm a Dish technician in the mountains of New Mexico. Those signals all look really great to me! Your signal levels will vary depending on where you are located. Even in the mountains of NM, with a clear sky, I can usually only get around ~73,~73, and ~51. The lowest we can have the signal and still pass an inspection is around: 58,58, and 39 on 110,119, and 129. I wouldn't make a trouble call just for that unless your neighbors is significantly higher. I bet you're right where you need to be though!
