Need a tarp for covering a 4-wheeler that sits outside. 10' x 12' should be plenty. A tarp for the grill ~ 8'x 12' would be nice as well. The cheap $12 tarps from Lowe's & Wal-Mart don't last a year. I currently use an old car cover made of Tyvek for the grill. It works well but is way too big. What about these sites? MyTarp.com & SpeedyTarp.com However, SpeedyTarp seems to not have any contact information on their website. What about Cordura material for tarps? I would imagine that a Miata car cover might not be too much overkill (in the size department at least) for the 4-wheeler.
