Anyone knows TBK TARP?
 

It's a tarp shop located inside the Flying J truck stop in Lake Station, IN (exit 15 off I-94). I talked to Mike there and he seems like a knowledgeable guy. Explained to me drawbacks of lightweight tarps made from "Kardura" and recommended to use a mixture of 10 oz and 18 oz vinil for a lumber tarp (18 oz material for the top, and 10 oz material for the sides). He said this way you reduce the weight by almost half yet the it doesn't jeopardize the strength of the tarp. Anyone worked with them? Do they make a good product?
