What advantage would it be to install a Transfer switch?

not cheating anybody but the campground electric bill. if everybody is pulling say 27 amps on their 30 amp circuit and the voltage drops to 108 or so and they kick on their autoformers and the voltage jumps up to 120 and they are now drawing 30 amps, aren't they "cheating" the campground?

Actually, the Autoformer can't use more amperage than the outlet provides. If you are hooked to a 30 amp outlet, the Autoformer can't pull more than 30 amps or it would trip the breaker. If you are hooked to a 50 amp outlet, it can't pull more than 100 amps (50 amps per side). Since you are already "authorized" to pull that many amps, you aren't cheating anyone out of "their" power.

In days of old I had that neat feature in a motor home.... A Wife.. Ok not always all that neat..
One day we pulled into a park and there was really only one acceptable site open, So I backed into it. Wife was not pleased and was harping that the woman plugged into the shared power pedestal was telling her "You won't be happy my voltmeter is always in the red") (fact is voltage was down in the 80s per neighbor's surge guard on occasion normally high enough to pass but often too low.
My voltmeter was always in the GREEN,
So why did I have green when neighbor on same circuit had red.
Shore----Inlet---Hughes autoformer---Transfer switch--RV
That is how mine is set up
Park rules in some parks prohibit Autoformer.. Which is why you need tools to lay eyes on mine. And of course the knowledge of where to tool.
Soon, I will modify as follows
Autoformer-----x x---Transfer switch
Autoformer---Surge guard---_Transfer switch.
This is a plug in mod. Once I get the Surge Guard modified for installation instead of plug in. (longer cords)

So after reading the responses of all you kind people the volt regulator would be the way to go it says it has a surge protector installed in the unit? Again the reason I focused on fulltimers was because we will be at different campgrounds as we see the country. As I have read each campground will be different and different time of day will make a voltage drop such as morning (coffee makers ect.), the purpose of choosing the voltage reg. is to protect my appliances in my coach.

I standby what I said. Naturally you cannot draw more current than what the circuit breaker is designed for on the pedestal. Few of us pull the maximum power the pedestal is designed for, especially 50 amp pedestals. But, if you use an autoformer in a low voltage situation, you are pulling more current from the pedestal than you would without the autoformer and thus contributing to the low voltage situation for everyone else that is originally caused by the high current draw throughout the campground.
It's simple electrical math. To get higher power on the output windings you have to increase the power on the input windings and in low voltage situations the only way to do that is increase current through the input windings. And since the autoformer is not 100% efficient, you actually lose some power through the autoformer, requiring an even higher current on the input.
