Ray ... you asked how often I used my tonneau cover .... none so far as I`m only on snap # 568 . On my previous cars , it was handy when parked outside in case of a sudden shower , looked cool etc . When racing back in the late 60`s , we used them to cover the passenger side and the open space behind the seats/rollbar for less wind resistance supposedly .
I`ve heard of some folks using them during the winter to try and keep some heat in the cockpit .
Your choice ... I think they can look cool , but do take a few minutes to put on and also take up some storage space in the trunk .
