I do not have a transfer switch at the camper (5th wheel; not Berkshire).
I plug the shore power cord into the generator in the bed of my truck.
The Franks works just fine with my Yamaha.
As to the "transformer on the pole" it was a "wink wink" to the autotransformer comment you made. The house protectors work plenty great for me. We also have a 6500 watt house generator for power outages.
As to campground's responsibility for brown outs; I can tell you from first hand experience that you will get "The Reserve Salute" (shrug) when you complain.
They will tell you it is the power company's problem and go talk to them.
Wow! that was close!
And I learned something new about the forum software!
