Lead acid batteries can handle up to 14.8v, so this mod won't hurt the vehicle with the existing battery.
The only issue with the alternator is in the AMPS it's capable of producing versus the load you plan to run, and you aren't running anything big so no issue. The voltage regulator comes preset for some reason to 13.2v. hence the diode. In older cars, it was totally normal to have an alternator pumping 14.4-14.8 all day long. AGM likes at least 13.6 to be happy.

you have been great. i have to take the diode and alternator accounting out of the equation now with the way my mind works. sounds like perhaps you were saying what i will be running wont affect the alternator but the battery could take a hit if i simply drop the agm in my truck. i wont trickle charge on routine, ever. especially if a special one is needed.
it sounds like i am still now rendered to just getting a fresh 24f traditional battery.
i like to hash things out like this, so your input was very appreciated and smart.
sometimes i wonder... cant put 33s on these trucks without with cutting part of the frame or body mounts, cant put a small agm battery in it without a bunch of considerations.
