Since being at our campground for the last week, our Progressive Industries EMS-30 has cut power to our coach at least 3-4 times per day due to low voltage. 

Because we are the Host in the park, we do not have the luxery of moving
our rig to another pedestal, an electrician is coming out to take a look at things but I doubt if the problem is something major the park will actually put the money needed into the problem to get it fixed.

So, I was considering purchasing an Autoformer to boost power to my rig when the voltage is low to prevent the Progressive from shutting down our coach, does anyone have any recommendations on a good Autoformer?
