2014 Phaeton 42' LH voltage drop
We have a 2014 Tiffin 42"LH Phaeton. When plugged into shore power you turn the key on and the lights dim a little and I lose 3 volts AC at the outlets. I am told that when you turn on the key the i...

This sounds like a DC issue. I would guess that when the key is turned ON the chassis/house battery solenoid closes which is causing the DC voltage to drop which in turn dims the DC lights. The AC voltage probably drops because the inverter/charger is ramping up the charge rate when the chassis battery is connected which is a load on the AC side. 3 volts is nothing to worry about on the AC side and may be normal if there is a load like the charger applied.
I would check the Magnum panel and see what the DC amp reading is and if it goes up with the key on. Also check the DC voltage on the panel and see what it does.
