Dash mirror- sucks.
Fender mirror- sucks.
Together, they still suck.
I went to Autozone (or Pep Boys?) and bought a small convex mirror (it is maybe 2" tall by 4" wide) for $2.99 that sticks on the windsheild with a suction cup. I mounted it close to the top of windshield and it is much better than either the dash or fender mirrors and it really opens up the field of vision. Plus, with the suction cup you can remove at a moments notice.
