Hi all, I have been having a problem with plugging into the shore power at our storage facility. They have all circuits run through GFCI outlets on the pole. When we plug in and we are not running any...

That's not the case. It trips all the GFCI's at the facility but is ok on a standard 30A (no GFCI).
We do not know all the GFIs at the storage facility are good. they are probably all on the same circuit. and wired wrong.
a cheap tester will eliminate the doubt.
to determine if it is the trailer, simply read continuity between the two hot leads and the common ground on the trailer plug, it should show and open.
If it doesn't show an open circuit, it would pop the 30 amp breaker at home or smoke something.

If a GFCI is wired wrong in any way, it will not work (trip) under any circumstances.
Further, a continuity check may very well not reveal the leak. The higher voltage will often cause continuity when low V wont. Think of this as an active short.
