A volt meter is important, but you need an ammeter to determine if an alternator is producing its rated output. Low voltage could mean either high load, or insufficient supply.

If it is bad don't get anything other than a Denso replacement. Anything else will just disappoint you.

Also a fun note is there is no voltage regulator on the third gens, the PCM controls it. Also the amp gauge is just there to make people feel good. It's numeric number scale has no bearing on the actual charge amount. Of course it does work good to know if you are charging or not but that's it.
I looked for a Denso as you suggested and did not find one after stopping at 3 places. Both tested bad at my friends and at Auto Zone. I could not hear the brushes when spun my hand and they both produced no voltage on the meter or the amp gauge. The reman I got ($141) comes with a lifetime warranty, so at least this will be the last one I buy.

I did both tests here to make sure.

All back together and it is charging as it should now. Dropped off the old one at my friends to check out the bearings, brushes, etc. Hoping I can get parts and rebuild this one as a spare.

I normally check all my gauges right after starting the truck and with this truck also have to look down 2-3 minutes later as the brain does not turn on the alternator immediately. This is the first vehicle that has ever done that.

Did some other maintenance stuff while I was in there. Cleaned all the battery connections and sprayed them with anti corrosion stuff. Power steering was a hair low so topped that off. Tranny fluid and brake fluid was up to snuff.

Did see a drop of antifreeze on the overflow return hose where it connects to the radiator. Had 3/4" to spare so cut it off and it now fits tight.
