If you are parked close to your garage I think the best way would be just run a 10-gauge (10-3) extension cord out to the trailer from a standard garage 120VAC Recpetacle and then plug in the trailer shore power cable into the end of the extension cord using a RV30-15A "Dogbone" type 18-inch long adapter from WALMART. You can power up everything in your trailer doing this but you will have to watch what is on at the same time. i.e. you cant run the air conditioner at the same time you want to run the microwave.
We have been doing this 24/7 here at our house when our two trailers are parked here. They are on separate circuits in the garage (each fed by a separate circuitr). One trailer is fed from a 50-foot extension cord and the other trailer is fed by a 75-foot extension cord. Just make sure the connection dont get warm to hot and always monitor the 120VAC voltage inside the trailer to make sure they are not below 110VAC before turning on the air conditioner.
We sleep out in our trailer all the time when parked at home - grandkids love it...
During the winter months I run an oil-filled electric heater set on low setting and sometimes run a 100W light bulb is a couple of places to keep from freezing things...
Works for us...
