Hello from NC Triad Area, I hope every one is enjoying there day. I have a Jayco 1990 deluxe series 1006. I haven't plug my viper in to a receptacle yet. I'm steal working from outside in. I would like to know how can I tell if my furnace work or not. What should I be aware of before turning it on and what does it use for heat, or does it use both. How do you plug your pop up to a battery.
