Yes it is very dangerous but not necessarily a shorted hot wire.
IF the trailer has a good ground and hot is shorted to frame,
it would be a "dead short" and should kick the breaker.
It could be a hot and neutral that are reversed somewhere, either
in the supply outlet or in the TT but again, if it was properly grounded
that should kick the breaker.
It could be a slight short to ground but more likely is a loose
ground or neutral somewhere.
Either way it's dangerous.
Rule of thumb-- NEVER trouble shoot any suspected electrical problem
in bare feet!!!!!
We're all curious what you find.
