Electrical help needed

After checking these things out, my very next phone call would be to CW to have them send a technician to fix this thing at no cost to you. This unit should not have been sent to you in this condition in the first place. Very shoddy service on their part.

Does the microwave and/or A/C work? If so then it is probably a GFCI problem. If they don't work, you could have a bad transfer switch like myself.

Lighting is 12 volt, so the genny has nothing to do with the lights working.

Does it have an automatic transfer switch? Ours doesn't. We have to plug our 30amp shore power cord into a receptacle in the storage compartment that is powered by the genny.

Do the receps work when plugged in to shore power? If not, check for a GFI recep.

Seeing you are from the Endless Mtns of Pa, you should check the link in my signature.

That sounds like a gfi problem reset it bu pushing the red button on the outlets.

The lights are probably 12V and run from the battery supply and not shore power/generator. Lots of possible causes including 1) no transfer switch and shore power cord needs to be plugged into generator outlet 2) bad transfer switch 3) tripped breaker at power convertor or generator 4) generator to generating power. Is there an outlet you can plug shore power in to rule out everything related to generator? Assuming a 30amp shore cord, you can get adapters to plug into regular residential outlets but you won't have enough power to run A/C and major appliance. You should get enough to check for power though.
