It ran fine last March. Why will it not start now?

Because of the nine months in between, not the running. Fuel left standing in a carburettor degrades and leaves deposits in passages narrow enough that a small amount of residue blocks them. The generator did not fail while running — it failed while sitting, which is why exercising it monthly during storage prevents most of these.

Can I fix stale-fuel problems with additive or fresh fuel?

Additive used before storage helps prevent the problem. Once deposits have formed, adding fresh fuel does not dissolve them, and the carburettor generally needs cleaning or replacement. It is worth trying fresh fuel first because it is free and occasionally enough — but it is not a substitute for the service if it does not work.

How far ahead should I arrange generator service for the January shows?

Before you arrive, ideally. The peak weeks concentrate an enormous population into an area with limited local capacity, and generator faults surface across the whole population at once. A service done at home in November is straightforward; the same service in Quartzsite in late January may not be available at all.

RV generator repair in Quartzsite–Yuma: the storage failure pattern

Whether to service the generator before the season or gamble on it starting when it is needed.

The failure here is annual and predictable, and the timing is uniquely bad. Coaches arrive having sat for eight or nine months, the generator is genuinely load-bearing because there is no shore power, and the moment of discovery falls in the exact weeks when local service capacity is most overwhelmed.

Stop-work system

Generators combine fuel, high-current AC, and exhaust. Carbon monoxide from a running generator is lethal. Do not troubleshoot a running unit in an enclosed space.

What is different about this in Quartzsite–Yuma

The dominant pattern is a generator that last ran the previous winter and has had fuel standing in it since
Fuel degradation leaves deposits that block the small passages in a carburettor, which is a cleaning or replacement job rather than a fresh tank of fuel
Off-grid, the generator is not a convenience but the backup to solar, so a no-start has consequences it would not have in a full-hookup park
The failure surfaces on the first genuinely cold morning or the first cloudy stretch, which is when everyone else discovers theirs too
The fuel pickup for a built-in generator sits higher than the engine's, so it also quits with fuel apparently remaining — a separate issue frequently confused with the storage problem

When to act

Run it under load monthly during storage, and service it before you travel rather than after you arrive. During the January and February peak, local capacity is committed days out and a generator fault can genuinely cost you the stay.

Next step

Work through structured triage for this system and you will end up with a written service brief: what you observed, in what order, and what has not been established yet. It is the document that lets a technician quote properly instead of guessing on arrival.

Being straight about what this is. No technician is signed to any territory yet — not one. We do not match you, dispatch anyone, or promise a call. What you get is the brief, and a request form that copies it to us so we know the demand is real. If you need someone today, take the brief and send it to a local technician directly; it works just as well that way.
