Our coach is a 40 foot and definitely a 8v92. The extra 5 feet and the torque of the 60 series is really what we (me) are after. Disc brakes would also be a bonus, although I am unsure what year they started. I am not sure about independent suspension as it seems to come with added maintenance costs and besides which I don't mind how mine handles. The newer coaches also seem to have a better fit on doors and panels. I love the rivets, and our budget does not allow for a XLII.
