charging issues

Any aftermarket accessories like a high power stereo, amplifier, lights, etc? What brand is the voltage regulator (please don't say autozone). How about the alternator? What is the size and capacity of your battery? How long between trips (sitting) and how long are you normally on the road (charge time)? Did you clean the battery terminals and posts when installing battery?
no stereo at all, only a sunpro tach,no other accessories at all. cables are all super clean, the VR is a mopar electronic, but is not brand new, the battery is a brand new 750 CCA , and lately i have only been taking short 10-15 minute trips. i would let it run to see if the gauge would level out, but i dont want to fry any wires.
