We bought the 3050S in July 2013 and the dealer had the vehicle >4 months between then and December 2013. The full-length slide kept binding up, ultimately requiring the slide manufacturer to tear it down and fabricate new componenets for it. It STILL takes multiple attempts to get the slide fully extended and/or retracted.
We had to replace the A/C unit, the microwave and the in-dash navigation / entertainment system is the least user friendly device I've ever used.
My wife and I cannot express how unhappy we are with this vehicle. :-(
