These truck tarps are thick at 21 mil and built to handle tough weather. They’re from from semi-trucks, making them perfect for covering hay, RVs, older trailers, and equipment during the winter. Most are 10 feet wide and 30–44 feet long, with some available in the 16x30 range. Most are 10x44 roll top tarps along with a good number of EPA tarps. Lots of uses.
