I will disagree for the funk after 6 months (if you use stable) two years yeah funky but you'll be fine for 6months. Do not just put it in, run around for 1/2 hr or more that will distribute it and burn and water in the oil. Instead of starting every month I would recommend to remove the battery, give it to your buddy with a tender (cheap $20-50) and have them put it on charge one day per month. I also would cover the exhaust pipes and cowl intakes (under hood at windshield bottom) with painters tape to keep critters out. In my unattached. garage in CT I also put in mouse repellant, it smells like mint it's supposed to keep them away. Bounce did not work for me, I think its just an urban legend. One thing you may consider (which I haven't tried yet but plan on) is when returning to disconnect the fuel pump plug (spare tire well) or pull the fuel pump relay before cranking it upon your return to get parts moving at just starter rpm before having ignition. Yes, indoor storage is better in a secure location but $$$$
Sta-bile and clean are the two biggies, I recommend this other stuff but it's probably not needed but it's simple/cheap enough.
