I certainly agree that the OPs wiring may be acceptable for the gen upgrade. But I don’t know his wire size, length or how much voltage drop would be acceptable to him. This is why I said in my very first post on this thread I said “You may need to replace the wiring…”. It’s so simple to check the wire gauge, estimate the length then run one of the free wiring calculators and then determine if the voltage drop is acceptable. Arbitrary statements without knowing the basic information is just that arbitrary.
My prior MH used a larger neutral from gen to ATS to CB panel for the QD 7500. So they understood the need for that MH and did not compromise with lower gen voltage at the main CB panel.
