My coach came with a Hughes 50 Amp Autoformer. I didn't know what it was so the web came to my rescue, as always. <br/><br/>That thing is pricey at $544.13 at PPL and it's one of the few thing that work on this coach. I will very seldom stay at a RV park. So is it something I need? My thought are no, someone else needs it.<br/><br/>What say you all.
