Welcome to the group.
One of my friends has a Voltage 3400. The only problem he's having is the double fridge. On the first outing(Thanksgiving 2010
), the fridge stopped working. We removed the outside fridge vent and by-passed a switch. I'm thinking it was the defrost switch or replay. It works great as long as it's by-passed.
He brought it to the selling dealer for repair with no luck. Thanksgiving 2011, he told me it still wasn't fixed properly, but had an appointment with another dealer who said they could repair the problem. I haven't heard if the problem was taken care of or not.
