I sell these as well.
The gold line series is a good stock replacement. No complaints so far. Decent price and there's a NAPA just about everywhere.

That's not enough depending on your setup. I don't have a CB(never really liked them but that's not relevant), so I don't have something that is totally inefficient, but what I do have is something that definately is draining with just one alternator when everthing is on(lights, radio(not the basic radio either Pioneer avic-z(or something like that, I'll have to look next time I'm at the truck)), amp(2 of them, one for door speakers other for sub), gauges, dashdaq) I get 14v on the Optimas, when I was using the bare minimum batters I was getting barely 13v, and both of those were on fresh batteries and one alternator. At first I thought the alternator wasn't up to snuff, but after I put in the Optimas(almost 2 yrs ago) it's held that charge, unless something else was going on only thing I could think of was the first batteries weren't up to snuff.

If you are robbing power to your vehicle with all of the other electrical stuff and requiring the battery to augment the alternator, you need a higher powered alternator or stop using all that stuff at the same time. If your headlights dim when the bass hits, you can solve that with a capacitor. But if you are overloading your alternator and preventing the battery from being charged while the truck is running, you are shortening the life of both.

For reference, I have a single alternator/single battery in my V10. I have 3 large amps running my sound system (300-800 watts rms each) - although I very, very rarely run them hard. Usually just moderate volume.
Even with that, I can run over 300 watts of auxiliary lights and still have reserve capacity on alternator - even at idle.
