Your best bet would be to pick up a trucktrader magazine and look in there to get a rough idea. I sold a 99 classic that was decked out with 1.1 mill. and 340,00 on inframe a year ago for 16K on Ebay then a month later , another decked out 2000 with 1.2 mill. and no motor work for 17,800. They were both wood floored,gauged out ,nice paint ,chromed out ,LED's in excess of 70 per truck. Both were Ser 60 W/13 spd I know they were a little low but was ready to get out of driving.
