I sold my 2001 double cab Tacoma without the Softtopper so am offering it for sale here.
The topper is grey, in great shape, no leaks, no rips, brand new zippers, in the storage bag and ready to be installed, all you'll need to buy is some foam stripping for the top of your bed rails. I have some heavy duty Velcro that I'll include (it's white, as was my truck, so if you have a dark truck you might consider getting your own -- cheap and available at hardware stores..
Lots of general information at the Softopper website: www.softtopper.com.
This topper is 3.5 years old so there is not an option for the screens you'll see at the website. Very versatile, keeps everything dry yet can be either rolled up or folded away in minutes.
Retail is $590, asking $375 OBO. Located in western North Carolina, pick it up or pay to ship.
