Looking at buying a 2011. I was wondering what the trade-in value might be. It is the truck in my signature. PS, PB, Tilt wheel, Power on both seats, sliding rear window, AM/FM/Cassette/Single CD Player, and Nerf Bars. Body and interior are in pretty good shape. Engine and power train has been well maintained with all fluid intervals followed. I have all the maintenance records to prove it. Any input would be appreciated.
