fyi. I Just recieved and installed my Extang Tonnoe cover yesterday and I must say it's a perfect fit. I have a UWS toolbox and have wanted a cover to fit with my toolbox for some time. After some searching I found one for a very reasonable $200 from www.truckaddons.com. Took a few days to get here since it actually comes directly from Extang but definately worth the wait. Highly recommended. I can definately feel a difference in that there is quite a difference in wind resistance. On my previous Tacoma an Extang cover was used as well and always found that it greatly improved my gas mileage which I'm already seeing a difference this go round.
