Inverter installation can be as simple or as complicated as you choose to make it. "Whole house" simply means plugging the trailer's main service cable into the inverter output BUT you do have to remember to turn off your converter so as to not create a closed loop and make sure anything than can run on 120 vac is turned off, such as a water heater electric element. If you don't want to do that each time you use the inverter you can install additional receptacles that are dedicated to the inverter output, just as I did. Your third option is probably the most complicated, installing a transfer switch that will automatically switch to whatever power source your trailer is running on. Your choice. ;)
There is of course also a fourth and even simpler option, which is to get a small inverter and plug the TV into the inverter and then connect the inverter to a convenient 12V power supply point, often a lighter plug where the TV is installed. That can be done by anyone who can plug things into other things, and for a pretty small load like a TV it usually works fine. (An XBox may prove more troublesome, as it's comparatively power hungry.)
