According to HERE you have an Ultra Light Weight 18ft expandable Travel Trailer.
What you are seeing is correct and normal for not having trailer plugged into a power company powered outlet, there is nothing wrong with your trailers' 120V electrical system.
In general, most RVs do not supply 120V power to the outlets when not connected to the power grid or your own generator.
Some RVs like Motor Homes often have built in generators and/or a large battery bank and a 12V DC to 120V AC power inverter.
It takes a lot of battery power to run large draw items like A/C, hair driers, Microwave ovens, coffee makers.
Your Trailer has a "converter" which is really a 120V AC to 12V DC power supply and battery charger, that unit cannot power 120V outlets as it is designed to charge the 12V battery and supply 12V to all your trailers 12V items when plugged into commercial power.
To power the outlets when no commercial power is available, you will need your own portable generator and for small low wattage 120V loads you can buy and install a 12V DC to 120V AC "Inverter" and you will need to add more batteries to your trailer.
