Jamnw, Not in the trailer but in the house that is also fed by the same panel, A receptical was "modified" to use the ground as a neutral. As far as I know, None of the outlets in the trailer were overloaded.

I have to say you need to hire or befriend a competent electrician to come put eyes on your situation and help you.

The first problem is the source. It needs to be 100% to troubleshoot a problem like yours.

Using the "ground" on a circuit is dangerous. The neutral is NOT ground although it is connected to ground. It is the easiest path back to the power source. ie transformer feeding your home

Your ground is/should be going to a ground rod at your home. This ground may or may not be at the same potential as the power company neutral.

I had a telco customer who had rearranged their home. Every time lightning struck in the vicinity ALL their phones would blow.
Phone interface is supposed to be grounded to the power ground. They had moved the power ground to the other side of the home. They left the telco grounded to the old ground rod.
That difference in ground potential was causing their problem.
They were mad as hell at Bellsouth thinking it was our fault. When I proved to them the problem was caused by them, they were very humble. I had to bury a #6 unshielded wire between the two ground rods.
Solved their problem.

You have to get your source right.
