I snagged a Pace Edwards bedlocker electric for my F250 short bed on Craigslist for only $600 with a brand new electronic control and 2 brand new remotes. After I sold the Undercover that was on the truck that brought my net cost of the Bedlocker down to only $200!! After cleaning it up a bit and installing it, it looked like a brand new cover. Works great.
Best of all is that when it is closed and the tailgate is locked it is a secure storage and keeps my 5th wheel hitch MINE!!
