The recommended HD switch will make long term storage very simple and safe. As an option, a battery tender can still be used to help keep the battery at peak power.
I see a real problem with that advice: people will buy the first $4.99 item they find. Such cheap crap will disconnect or go resistive while the engine is running -taking the battery out of the circuit, endangering some very expensive modules.
The battery is your secondary voltage regulator and "brute force filter", operating the car without it is dangerous. A TRUE heavy switch is fine, EMS and some Fire vehicles have them.
