Hi and welcome. this is what i do when diagnosing this type of issue. Start at the source. Do you have power at the plug at your house? if yes plug in the cord and check power at the end that goes into the trailer if it is a plug. got power? yes with it unplugged pull your breaker panel. the plug the cord in. Check for power at the panel. if yes check your breakers. if no call the dealer should be under warranty. Last thought since you have a generator. is yours one you plug your power cord into or built in with a transfer switch? if it has a transfer switch that could be bad (warranty).I am assuming this is a new trailer as you said 2017. if you can post more info that would be very helpful. like did it ever work correctly. Also the plug at your house. is it a ground fault or on a ground fault breaker. I have had mine trip as i was plugging my cord in. good luck let us know how you make out.
