Q-How do Dice Caps apply to armor? A literal reading of the SRMFAQ Revised would not allow vehicles or trolls decked out in armor to receive their appropriate values.

A-In short, they don’t. Dice Caps apply to Skill Tests, whereas Armor is generally applied to Damage Resistance Tests. If, for some reason, your character was to roll a Skill Test that involved Armor (say an Athletics + Armor Test) then the standard caps for a Skill test would apply.
