Is it connected to the mains electricity supply? If it is, you will
probably need to consult someone familiar with your local electrical
codes as, at least in the UK, rules for such structures are much
stricter than for permanent buildings. At the very least, that will
affect if and how you provide an RF ground.
You haven't actually specified what the constraints on your antenna are.
Are you constrained to not having an external antenna? Are you
allowed one but it has to fit within the area of the trailer. How high
above the trailer can you go? Are you allowed to install ground rods
(electrical codes apart)?
Without either an external antenna or a ground connection, you are
probably lost.
