Turns out their ground on the top of the spot pole was corroded which made the voltage in the trailer swing from 0 VAC to 75 VAC to 125 VAC to 175VAC. (Yikes!!) I could literally sit and watch the volt meter continually swing with nothing going on at all, then the voltage would stabilize at 125 VAC and as soon as we put any load on the circuit, the voltage would drop down to 0 VAC then when we took the load off, it would shoot up to 175 VAC and bounce as if it was trying to go higher.
Actually, it was a bad connection on the NEUTRAL that caused the wide fluctuations in voltage.
