Bedcovers are as plentiful as wheel choices. You have solid roll tops like Retrax or the hardflip covers or soft tonneau covers. Usage is a big factor in making the right choice. If you want protection for items in the bed, definitely a hardcover. However, if you offroad aggressively, hardcovers don't do too well (In my personal experience with a retrax on my Gen 1 and others I have seen including the hardflip covers). Soft covers basically just give you protection from the elements, but they do great offroading as there is plenty of flex in them.
