Finally found a cap so my roll n lock tonneau is up for sale.
I'm asking $300. It's been slightly modified with added Thule track.
You can read about this very cool retracting vinyl covered aluminum tonneau cover here:
You can also download installation instructions from the site.
Thule bars and accessories shown not included, just the Thule track on the bed rail.
Tonneau cover can be delivered to parts of Boston and as far North as Augusta, ME. It could also be shipped as it's broken down, but it might be prohibitively expensive.
Thanks for looking.
