I traded a 40' Allegro Bus with 75,000 miles when we bought the 2013. We had a QGP and loved it, at least until the DW fell in love with the rear bath in the 2013. Oh well, when Mama's happy, everyone's happy.
We seriously loved the 2008. We did have the wet bay floor replaced at Tiffin, and the usual occasional warts, but it was in first class shape when we turned it in and the new owner got a peach.
Good luck with yours.
