Genny sets under the porch wearing a cover, it has a maintainer pigtail wired up for a occasional charging/ maintaining.
I built a trash bin holder to hold the wheeled trash units and during outages that are weather related - I roll the bins out and place the gen in the covered bin holder.
I have a 30 amp cable that plugs into my isolation transfer switch and I power the house with one cable and forgo 220 Volt appliances during a power outage.
At the house I have 3 sets - a Yamaha 3000iseb, and 2 Honda 2K's with an extended run tank setup (one a companion with a 30 amp connector)
I keep the hondas empty and that yammi full to the brim with vp105,exercise it every 6 months, and keep at least 2 metal not plastic 5'ers on hand at all times.
This gives me about 90 hours of run time on the yamaha at a low load.
