Recently purchased a Softopper and love it. 4 clamps to secure to the top of the bed, snap the sides and viola' you have a versatile topper that is easily taken down just like a convertible or a boat. You can also roll up the back window and sides to make a cool looking bikini top. They are available in black or tan and have sizes for most trucks.
Not a week goes by without someone commenting about the topper. I've come out of the local gas and sip while getting my daily jug of pepsi only to find someone examining the topper on multiple occasions.
Have a look at Softopper | Soft Top Truck Caps and Canvas Camper Shell Tops
, if that is wrong they are located in Boulder, CO. Good luck
