The R44T or R44TS is a good choice. I would gap them at .035 - 0.40.

The next time my son and I work on the truck I will try and verify it’s getting a full 12 volts. What are the symptoms if it is not getting a full 12V? Right now the truck seems to be running fine.
I assume the 12V you are talking about is at the connector where the red arrow is pointing in the photo? Do I need to remove the connector to verify the voltage? Or do I need to back probe with it connected? Does the truck need to be running to perform the voltage check?
Does the R44TS provide a advantage over the R44T? From my quick google search I see the TS has a extended tip. Does the extended tip provide better performance? Do I need to be concerned about any interference with the moving parts in the engine if I choose this plug?
Thanks for your help.
