You'll love the truck. I have a 2002 F250 2WD crewcab short bed with the 7.3. Runs great and tows great. As others mentioned, the truck needs the cam position sensor replaced (factory recall). The sensor should have already been replaced. Lots of power from that engine. The only other thing I've done in the 6 years that I've owned it (other than normal maintenance) is have the oil sending unit start leaking oil - the o ring gasket went bad.
I have the RollnLock bedcover. It locks so I can secure my generator and other things. If I bring bikes I usually travel with the cover open and have the bikes mounted upright in wheel blocks on a wood frame. The best option may be the shell like 2air has which allows bikes and everything in a huge garage-like space. What you get depends on your budget and how much stuff you have that you want protected from weather/theft.
