"it INSTANTLY pops the GFCI on my house"

Is the GFCI in the outlet? Or a breaker in the panel? Outlet GFCIs don't normally pop on overcurrent and there shouldn't be enough running in the MH to pop 15 amps anyway.

You have a common problem. It MAY be due to a construction fault in the MH where an errant screw has pierced the insulation on a neutral wire which wouldn't affect normal 30 amp connection/operation, but would definitely cause a ground fault when plugged into a GDCI circuit.

The other issue people find is that their MH was wired incorrectly with the neutral and ground busses bonded, which is incorrect and also causes a ground fault.

Some say the GFCI breaker in the MH causes the problem and you can open the breaker to that circuit in the MH as a work-around. That should not be the case, but if it works, it works.
