WRT the ground-based blower - at some point, moving air makes as much noise as the engine, so this isn't surprising. For charing, many newer trucks come with robust power systems for running electrics. Obv not an expense to be taken lightly, but we're getting there. Ford has the most compelling options right now - right up to 7.3kw system (I believe that's with the engine idling). I believe that with the hybrid drivetrain, you can use a not-insignificant amount of electricity with he truck engine off.
