Autoformers - what's available as of 2016?
Have been thinking about getting a 30 amp autoformer. Never thought we'd need one but have been to enough CGs now with really bad voltage problems to warrant one. There's lots of Hughes RV2130 aut...

Is there anything like PD EMS with autoformer, that would keep it 110V+-few% and would only shut down when it can't keep it close to 110 anymore?
Frank's Superautomatic does that.
I have the 30 amp and I don't recommend it.
There is no delay to the power off-on cycle. Under the right circumstances I have seen it switch on-off-on-off in rapid succession.
Thermal circuit breaker rated 35 amps seems to trip way too easy if running 20+ amps continuous. Anyway it trips before the 30a pedestal or 30 amp RV main.
Voltage seems to hang high for too long as it will hold 128-129 volts when it could just bypass. Also my Kipor has a bit high voltage under no load so it has presented an issue if nothing is immediately on. For me it seems to cut off a bit early on the top side.
Mine is eight years old and not really used much although a few times it was really needed to correct low voltage and keep the air on.
If spending today I would prefer the PowerMaster and they seem to be out of production right now.

The out of production Hughes RV430 with more steps seemed like a winner. Not sure why production stopped. I would be tempted at a used one if the price was right and the seller would give a 30 day warranty to return.
