Not all rubber feet are the same. You need soft, squishy feet. The feet need to be large and soft enough that they noticeably deflect under the weight of the generator. The best vibration isolation will be with feet that deflect 1/2" under the weight of the generator, but feet that deflect 1/8" should get the job done. The hard rubber feet in the local hardware store are useless in this application.

The number of feet does not matter. What does matter is that the feet are located so that each one of them deflects about the same. Three feet is the minimum, and there is no maximum. I once designed a vibration isolation system for a vibrating machine that had six rubber isolation mounts.

A good source for rubber mounts is McMaster-Carr: https://www.mcmaster.com/products/isolation-mounts/.

06 Canyon: The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.

22 Maverick: Summer 2022 burned 62.74 gallons in 3145.1 miles for 50.1 MPG.
