I am not sure if anyone else suggested, but did you check the circuit breaker on the generator? This would be the first place to start.
If the circuit breaker is okay next you need to make sure that the generator is producing power. This can be checked at the automatic transfer switch. Remove the cover and determine which wires are coming from the generator. There should be three sets of wires: one set from the generator, one set from shore power, and one set going to the power distribution panel which is most likely located inside the MH. With the generator running, use a VOM meter check each set of wires for voltage (120 VAC). If you have power coming from the generator, then the problem may be the transfer switch.
When plugged into shower power, does everything work? If so, then the transfer switch is not recognizing the power from the generator and is not switching over. The transfer switch most likely has 2 relays. One of the relays may be bad or the the contacts may be stuck together. Also, there is a time delay when the generator is started when shore power connected. On most MH's the generator takes priority over the shower power.

yes, all the shore power items are fine. seems strange since the genny only has 24 hours on it. where would i look for the genny circuit breaker? somewhere on the genny itself? there's no circuit on the inside breaker box marked generator. thanks

On my Onan 5.5 KVA generator there are two breakers right alongside the start/stop/prime switch on the generator. They're accessible with the generator box front cover removed.

Is your MH power cable plugged into the generator socket? You unplug it to plug into shore power, but on some you have to plug it back into the generator socket to power MH.

OP does not have a problem getting the generator to start/run; it doesn't put out voltage. Starter fluid will not help his problem.

We had the same problem with our generator. After changing the transfer switch, checking breakers and whatever else was suggested, nothing worked. Took it to an Onan dealer. The problem was a bad voltage regulator.

Two thoughts:
1: The breakers someone mentioned up-thread.. Sometimes just vibration from driving down teh highway will "tripp" these things to off. Not to mention the major shake up when the generator shuts down.
2: And this happened to me... Bat auto transfer switch.
(Thankfully it happened during the warranty period).
