Upon further checking, here are some of my findings:
1), The Newell AC voltage meters are fed directly from the AC input from the AC transfer switch bypassing the rear AC power panel in the rear closet. This means even if you turn off the 50 AMP main circuit breaker in the rear coach, this 120V AC feed line is still alive at the overhead of the driver's seat, and the voltmeter remains active.
2) The two Amp meters are fed directly from the two donut inductors because the AC voltage at the meter terminals and the donut wires are the same. And it's the same color-coded wire in the back all the way to the front.
No Power Reading in the front
No Power Reading in the rear closet
Power On reading in the front and back, the observed reading fluctuates and not quite stable.
3), Swap the two 2 wires behind the L-1, and L-2 amp meter again, the bad reading disappear. This seems to indicate the original wiring (from the previous owner rather than from the factory) was erroneous. AND the two donuts behind the power panel in the closet and two amp meters have to be a different model. But this has to be confirmed. I just ordered an inductance meter. Once I get it will test it again.
