Don't know why anyone would say that. There is a transfer switch on the power line into the MH. It favors the generator. So when you are on shore power and start the generator, as soon as it stabilizes and starts outputting power, the transfer switch will change your AC power supply from shore to generator automatically. At that point there is no need to stay connected to shore power, but there is no need to disconnect it just because the generator is running. (In my 2300, the transfer switch is in an electrical box under the bed. Not sure where it would be in yours, but it is there somewhere.)
When I installed my power management system, I did it after the transfer switch so I have surge protection and under/over voltage protection, as well as a digital readout on power, no matter whether I am on shore power or generator. That does leave the transfer switch "exposed" to possible surges, but I prefer having the protection on both shore and generator.
