I think my Truck Covers USA American Roll Tonneau Cover is great. It is well made and fits my truck to a tee. I installed it myself in about 3 hours. I made a few stupid mistakes and I'm sure I could have cut that time in half if I were to install another one. It has not rained since I installed the cover, so the jury is still out on how waterproof it is, but it seems like it will do fine. I have already noticed an improvement on my gas mileage with the cover closed.
