Welcome to the club
@Timber, Your going to love your P500.
As for your question. This topic has not really been discussed before.
I hook mine up to the house alarm system. Only forgot about it a few times and pulled it out..
I would make sure you get the biggest chain and lock you can find. Be sure to hook it to the main frame somewhere.
Bad news is... if they want it bad enough, Well... Its gone no matter.
Seeing this is one of your first concerns, You need to be looking at insurance ASAP.
