Sorry, I can't help you with your question, but if you call the office they will be able to answer it. I've been using them for several years and they are awesome!
I'm not entirely sure you would have to call Mr Morgan or talk to one of the reps that work for him
I believe you can, as it being your vehicle. The staff there are very helpful so I would call and inquire about usage while in storage. Each vehicle stored in the building has a battery tender hooked to it to maintain the battery.
