Ok if you plug in like this

Park--Surge guard (See note)---Hughes---RV

Note: and the surge guard is one of the good ones that cut you off if the voltage is too low or high.. IT will cut you off when the uncorrected voltage goes too low (i think 109)

I think we are in agreement but.... it was technically correct but a little confusing they way you wrote it (first reading it looked like the above was a reasonable option).

To clarify a bit more:

If you put the surge guard upstream of the autofomrer (as shown in the example above)...it will likely cut power due to low voltage at the pedestal when the autoformer is well within it's capability to boost the voltage to acceptable levels.

So if the pedestal is at say 102v, the autoformer boosting at 10%, would take that up to around 112v which I would be fine with. But since the Surge guard sees 102v, it cuts power to protect your system and the autoformer never gets a chance to boost the power.

By putting the autoformer upstream, it takes the 102v power and boosts it to 112v and the surge guard sees 112v and is happy to pass the power thru to the RV.
