I have a Tonneau Cover for sale that I bought for my Tacoma but it doesn't work with the Bed Extender. It is a Truxedo Brand and it's only been on the truck for a week, so its like new. I paid $475 for it and have everything you need to install it. Make me an offer if you are interested. It fits a 5' Bed. Thanks.
P.S. I did upload a couple of pics so you could see what it looks like on the truck but I only had my phone to take them with so it doesn't do it justice. If you want to see them go to my profile pics to see it.
