2008 F550 with service body 6.4L diesel Great truck runs great Inside dimensions of bed are 54 1/2" x 106" DVD / Bluetooth stereo Wired for a CB radio (just need the head unit) Only reason I'm selling is because a bought a new truck If you're locking for something like this you know they are not up for sale often, im too busy to go back forth with a million questions that go nowhere, if you're interested contact me to set up a day to come look at it and I'll answer any questions then, unfortunately there are too many people on this site that waste too much time.
