How many amps does a stock alternator put out and how long can I get away with running a stock alternator if I add aux lights drawing 10-20 amps each? At what point do I upgrade?

You don't need a larger alternator. You do, however, need a larger reservoir - one large battery or two batteries for the additional load. As long as you put in more than you take out of the battery system, that'll all that matters.

Lastly, if you need a deal on the battery/batteries let me know I will take care of you out of my store. Also, if you need 0/1 gauge wire, i have a huge bunch that i can take care of you on and also connectors (no crimping required).
Practically, a dual battery set-up will be able to easily provide the reserve most need.
Second would be going to complete drycell batteries like the optima. You should use redtop for the engine and a yellowtop for the accessories.
IMHO if you're doing dual batteries, do them both Yellow tops matched in type and age. The Yellow/Blue tops are rated as both starting AND deep cycle.
And... if you want overkill.. The D31A fit for me. Some people have some cable length issues though as they are center top posts.
YMMV.
Yes, I would do the same also. But the only thing is that the yellow top is not warranteed by optima if it is used as a starting battery.
