Re: Recommendations on a bed cover??
I've got an Extang Full tilt. It hinges up or it can be rolled up. If the tank sticks up above the bed rails you may need to have one custom made (which Extang can do). I've had good luck with the Extang covers but there are other good ones out there. The only problem I have had is snapping one up when it is really cold. Now that I live in GA, that is no longer a problem.
