complaints when using a hughes autoformer

Boosting 100 volts to 120 volts, with wattage remaining fixed (same load), means your transformer will drawing more amps over an already overloaded distribution system to make up the volts.

I can see a park with a sub-standard system being upset about blowing a main transformer or damaging lines if everyone were running their own transformer.

It will make the problem worse for others on the system that don't have their own transformer. Your transformer will only cause the voltage to drop even lower for others.

Given today's society, the me-first thinking that's popular, lowering someone else's voltage is not my problem, others can buy a transformer too of course.

Here is the statement from Hughes:

"How Does it Work?

Autoformers are used in industries to stabilize voltage and lower the operating cost of equipment. The Autoformer has 5 windings: 2 primary and 3 secondary. All models have surge and spike protection. When the unit is in Automatic and the park or input voltage is 116 volts or below, the output is 10% over the input. When the input is over 118 volts, the output is 2% over the input.

The Autoformer DOES NOT take power from the park.

It does not affect the park or input voltage, or make electricity.

What it is doing is changing the voltage – amperage relationship, lowering the amperage and raising the voltage. Since appliances run better on higher voltage, lower amperage, less overall power is used from the park, and better service is enjoyed from your RV

An Autoformer running at full output (50amps) will use 1 amp, but will cause appliances to cycle more often and run cooler. This will use less total power from the park. "

If I am reading this correctly, the Hughes works by sacrificing Amperage availability by boosting voltage based on the Wattage demand of what the RV "appliances" are demanding. Net, the ones you need running will run more efficiently, but you will not be able to run as many since the AMPS will not be available. If that is correct, a person using an Hughes Autoformer isn't stealing anything from the park or anyone else in the park.

To answer the OP's question: I have used the Hughes Autoformer with several RV's and have never been questioned by any Park I've been in. Many parks have been upgrading their electrical and I find fewer now that have low voltage issues than I used to. Although on hot days with everyone's AC going, the voltage does tend to drop a bit in mid day even in parks with good electrical. I use the Hughes to protect my AC and other "appliances" from struggling on too few volts.
