Just one more post on this...
An earth ground on a generator is essentially meaningless, as earthing the ground is not part of the circuit at all unless it is made part of the equation via neutral bonding. Therefore, a ground stake is only going to be a benefit if the neutral is bonded, but this benefit is worse than not bonding and not driving a ground stake.
It is all about circuit path and what is included in the path. My contention is that using the earth for neutral in the electric grid is a built in concession to safety that an isolated gen set is not subject to unless it is made subject to this concession to safety. (Whether intentionally or unintentionally)
Many electric codes are written to reduce the influence of the built in hazards of using earth to transmit one of the legs that can complete a circuit.
I am not saying that using earth was a bad choice, but I am saying that an isolated gen set not running an earth neutral is safer on a fundamental level than running on shore power.
