This is pretty typical dealer "schtick". There is something called the Priority RV Network. If you buy from a dealer that's a member and you're on the road and need emergency service another participating dealer will put you at the "front of the line". Unfortunately its a pretty small network right now.
Good to know about the slide. Our X20E has a Schwintek slide. Never had a slide before so I'm hoping for no troubles.
