Fuel Stabilizer and Long Term Storage

So I was hoping to get some people's opinions on long term storage of my Tacoma. I recently moved to a city where I walk everywhere and haven't even driven enough to fill my tank in the past 3 months. Should I be using a fuel stabilizer or is that just hype? Also, is there anything else I should do to ensure my truck is ready to go when I need it since it's not being driven for weeks at a time?

 

I suppose I could start it once a week. I park it in a garage to get it off the sketchy street where I live, so my truck is a few miles away from me.

 

When I store the Corvette I put stabil in and leave it on a charger. Watch the battery, have gone through 4 in 6 years. I try to start it once a week and get the brake/stering fluid going. Heres the charger I use.
