The new Diplomat is also out there...but it is basically a rebadged and dressed up Fleetwood upper level DP...Mine is as solid as a rock and although there were issues, (including the Monaco legal mumbo jumbo), they were taken care of by the manufacturer of the components..it's one of the reasons we ended up keeping this coach rather than trading right now (that's a long story)...If the coach were maintained and kept up with , no reservations about the one you are looking at (note if it was the RR4R chassis, than the previous trailing arm issue brought up comes into play)
