Which one runs an RV air conditioner?

The Efurden. Its 4500 running watts and 6000 starting watts cover most 13,500 BTU RV units. The Generac's 2500 running watts is too small for that load.

Is the Generac worth the extra money?

Only if portability and carbon monoxide safety matter more than watts. At $749.00 versus $399.99, you pay about $349 more for half the running power but a 59.5 lb unit with COsense.

Which is better for home backup during an outage?

The Efurden. It can carry a fridge, lights, and a furnace blower at once and runs up to 9 hours on 3 gallons. The Generac is better suited to small loads like a fridge and phone charging.

The Efurden is rated 70 dB at 23 feet, which is roughly normal conversation level at that distance. The Generac's published 0 dB figure is not usable, though inverter designs and Economy Mode generally keep it quiet at low loads.

Can I lift either one into a truck alone?

The Generac at 59.5 lbs is manageable for most adults. The Efurden's weight is not published, but a 223cc 6000W-class unit is typically 90-100 lbs, so plan on two people or a ramp.

Do both protect against overload and low oil?

Yes. Both list overload protection and low-oil shutdown. Only the Generac adds carbon monoxide shutoff through COsense.
