Inverter
The voltage shown inside the coach useing a plug in meter shows 130+ volts. This does not seem normal.Is there a regulator on the inverter, that may be going bad? The inverter is a Xantex Freedom 458.

Actually, there may be nothing wroing with your inverter. 150 volts sounds about right for that unit. The Freedom 458 is a modified sine wave inverter. Modified sine waves are not true sine waves, they are squared off. Voltage is actually measured at RMS levels on a true sine wave, which will peak at 170 volts but only for an instant and then return to baseline. The RMS voltage will read 120, which is what you want. But a modified sine wave is square. It shoots straight up to 150 volts, stays there for a while, and then falls to the baseline.
