I am about 20 miles away from the tarp wharehouse, so shipping isnt an issue. I have read about them not stretching, but for the cost I can buy a much larger liner so hopefully that wont be much of an issue, a 14' by 48' is around $50 from them.
I have lurked on several other forums and seen pretty good reviews with the Billboards, the negatives were holes around the edges like finsNfur mentioned.
I plan to use old carpet as a pre liner, I have a friend who owns a carpet showroom and he will have his guys drop off what I need. I am glad to hear that it works well.
