Review on Spider Waterproof Smart Tarp Adjustable by Paul Abs

Does what it says on the tin. Appears to be well built. I just want the size description to show the size in feet instead of a small or large bed. With base cabs, entry cabs and 4-door cabs all on compact, medium and large trucks, it's hard to know if you have a big bed or a small one. I never had all the truck options so how would I know? I ordered a little guesswork because I have a medium sized truck, but with a 6ft flatbed I feel the tarpaulin is too small.
