I use mine as a truck too much of the time hauling firewood, horse manure, compost or topsoil to want to cover the bed, but if I didn't, I'd still lean toward a capper rather than a Tonneau cover just for the added space and the ability to use it as a camper on occasion. However, if you're using this entirely as a city truck and just want to keep things secured out of sight, out of mind, then by all means, they're a great way to hide your stuff and protect it from the elements.
