Evening gentleman ( and ladies)
Living out here in the country for the past 20 some years, I 've learned to drag out the genny every 3 day weekend.
Our only way in or out is a single two lane road that has poles that attracts drunk drivers.

If not that, it's the weather (like last weeks power outage / road closure)
Before you buy one, figure out what you want to power.
We have been using a Coleman with a B & S engine for the past 6+ years on a regular basis and the only issue so far was to replace the rusted out governor spring.
The wattage on my unit is 3000 running / 3750 max with a 4 gallon gas tank that runs up to 11 hours @ 50% load.

Think I paid around $450 at Home depot back then
The control panel has 2-120V 5-20R duplex outlet, 1-120/240V L14-30R outlets and 1-12V battery charging outlet
My fridge needs 2400 watts, the freezer 210 so the 3000 watts is ample. That 12 v dc plug is useful to recharge deepcells while keeping the food cold.
With the 240, I can tap into the sewer pump panel and that comes in handy.
I turn off the gas and run her dry so I don't gumout the bowl float before storing and when needed, she fires up easily.
Gas gets treated with Lucas and Stabilizer and after 3 months, I rotate it out.
Always keep another three (3) 5 gallon gas cans full and rotate them out regularily also.
Another issue is noise.

You can hear mine running for sure, but they don't need to be running constantly.
The small Hondas are pretty quiet but not enoughg juice.
If you chain 2 of them together you get more juice but burn twice the gas.
Looks like I might hook up that propane attachment on previous post (Thnx BassMonkey).

I have the same make as that one but the 3000 watt model and always maintain 4) full 20 gal propane cylinders
