Congratulations and welcome to the JOF.
You are ahead of things if you have a PDI to follow. I don't recall reading anything online specific to your trailer.
Because you are a 'newbie', I'd suggest you actually OPERATE the things the tech may talk about. For example, the furnace, air conditioner, water heater, etc. If you actually operate them, chances are you will fewer doubts when you haul it somewhere and spend your first night in it.
