It is my understanding that the Hughes autoformer ( at least the one I have ) has basic surge protection. But it essentially a one time deal, after that, back to the factory for work. I called them regarding the sequence of setup for the autoformer and my Progressive surge/voltage protection device. They recommended putting the autoformer in first so that it has the opportunity to raise the voltage if needed, but that left it exposed to spikes. I ended up getting a cheap spike protector in front of the autoformer, which then feeds into the progressive unit.
This is consistent with Hughes RV2130 online manual, page 5.

I would not buy an autoformer for surge protection.
Ditto.
The Hughes autoformer manual hedges at just how much protection its autoformers offer: "Voltage booster with some surge and spike protection"
Exactly what does "some" mean? Hughes doesn't tell you.
It sounds like a Hughes autoformer has some surge protection, but no electrical fault protection (open neutral, open ground, etc).
Make that 3.
I have both. I hook them up shore > Hughes 50 amp > EMS-PT50C > ATS (Surge Guard 41260). This allows the autoformer to boost the volts before the EMS-PT50C shuts it down. I do not think the Hughes has enough surge suppression and the three together provide more than enough. Actually the SG 41260 does not provide enough surge protection, that is why I have the PI.
