Which is better for RV use?

The WEN. It is an inverter generator with a TT-30R outlet, 58 dBA noise and 100 lb weight, which suits campgrounds and travel trailers. The Westinghouse is too loud and too heavy for typical RV sites.

Which is better for home backup?

The Westinghouse. Its 9,500 running watts, 240V outlets and 14-50R receptacle let you run a transfer switch and power a furnace, well pump or central AC. The WEN tops out at 3,500 watts on 120V.

Is the Westinghouse worth $299 more?

Yes if you need 240V or whole-house backup, since no 120V inverter at this price covers those loads. No if you only need RV or tailgating power, where the WEN's quiet inverter output is the better fit.

Can either run a window air conditioner?

Both can. The WEN's 4,500 surge watts start most 13,500 BTU RV units, and its inverter output is gentler on the compressor electronics. The Westinghouse has far more headroom for larger or multiple units.

The WEN by a wide margin: 58 dBA at quarter load from 22 feet versus 90 dB at 6 feet for the Westinghouse. The Westinghouse is a conventional open-frame unit meant for outdoor use away from living spaces.

Do both run on propane?

Yes. The WEN makes 3,150 rated watts on propane and switches fuel automatically. The Westinghouse makes 8,550 running watts on LPG and includes a propane hose.
