At $80K new today you are not high end. Cooked medium well maybe but not well done. Really well built 5ers today are going to be over the $100K mark new real easy.
Depending on age & condition finding even a DRV Mobile Suite under $50K won't be that easy. Check up on some of the builders frequently listed here. Study the specs on the websites then go out for a touchy feely look, paying close attentiion to the usual fit & finish, quality of hardware used, running gear for wheel size, arrangement of spring hangers on the frame, how neat the wiring is arranged in places that are normally out of sight, anything that separates quality build from the junk that so many are.
