Good advice, which I also fail to follow on a regular basis laugh

When sizing a generator, keep in mind that a large one will use considerably more fuel than a small one, even when lightly loaded. If you just have 500 watts of lights and TV on, the whole-house unit will be expensive to operate.

I have a remote-start 2.5 kw Onan in a hut the size of a large doghouse with two 6-gal. outboard motor tanks. It will run lights, TV, furnace, and my CPAP machine and sips fuel... the thirsty 10 kw Onan rarely is needed except to recharge the well tank and run the water heater. twocents
