You may be able to get some idea of prices by checking the
PPL Motorhomes web site. They publish the prices that
motor homes actually sold for from their consignment lot. These the actual prices a willing buyer and a willing seller could agree on. They are not arbitrary discounts from arbitrary retail prices. For instance, in NOV of 2011 they sold a 36' 2005 Winnebago Journey 300hp Cummins w/2 Slides for $72,000.00
Hope you find this helpful as they list sales over a range of years with a good sampling of model years and models.
