The 2006 Roadtrek Adventurous (2005 Mercedes chassis) has the Mercedes seats on swivel seat bases made by an Ontario company, Cornel Weldon (sp?), according to tech support at Roadtrek.
This means a Mercedes dealer needs to work on the problem unless I can get an RV tech to look at it independently.
Dan, the service manager at Van City RV in St. Louis, where we bought the van, recommends taking the seat off the swivel base and using a rubber mallet to put the seat back on the slide track. So I have an appointment with Mercedes of Littleton, CO, and I'm trying to reach a mobile RV tech. The rear seat slide tracks can't be used to temporarily replace the problem slide track.
I don't want to do this myself. And I don't want to pay Camping World to diagnose the seat or work on it.
Neither the very knowledgeable tech support guy at Roadtrek nor the service manager at Van City had heard of this problem or seen it. So I'm going to patent it.
