Great topic to new Prevost owners....
Here is some free advice for all the new Prevost owners. Buy a surge protector cheap one, expensive one, used one. Second piece of free advice. Plug it in to check the power pole ...before you allow the RV park pole power into your bus.
Had I not followed this simple 1,2,3, step my bus would of still been in Texas hill country. Make a long story short the previous parking RV probably pulled away from pole with the power cord attached to pole. When I plugged in my $300 Progressive surge protector by itself, flipped the switch. What happen was the big bang as they say and the end of my first surge protector.
Many convertors build surge protectors into there bus. I would prefer to sacrifice my hand carry surge protector then bet all the protection on bus installed and what other damage might happen to bus.
Pictured is the Progressive I now carry. cost about $100 bucks used, $150 new. Don't travel without one.
