Turbo backfire

Only indication anything was wrong was a slight noise when accelerating and a smell like like wires and plastic burning. I pulled over, left engine running and walked around coach then slid underneath and checked for anything unusual, nothing, no noise, no leaks no smoke. when I pulled into the RV park I found my jacks doesn't work and the lights in the bedroom and televisions don't work. It was the next morning that I checked the air cleaner compartment and found a lot of melted plastic. My wife hears everything and she didn't know anything had happened until I told her something wasn't right when I heard a very quiet hum and then the smell. Never any loss of power, in fact it ran like a scared deer.

I WANT A NEW NEWMAR GASSER, You think this is a good excuse. Beautiful machines but when you get my age you just don't buy a new anything unless it's a new bottle of pills.:)
