what are the pros & cons of having two alts. i really have nothing on the truck that needs anything extra, but i was thinking it might give more consistant voltage having two of them.

One good one will beat two bad ones any day....

The voltage consistency is a function of the regulator.

yea..i dont think the possable advantage..(what ever that might be) would be worth the H/P it would cost. and one more thing to break

I don't see a whole lot of point in it. Especially in a truck without a whole lot of stuff. For consistency check the voltage regulator. Get one of the more expensive $40. Not one of the integrated, sealed up cheap $14 ones. They burn out real quick.
Also you could get an alternator that produces more power.
