Probably not the correct place to post this one but let's give it a try. I am losing the black plastic corrugated material that attaches to the underbelly of my toyhauler. It is 8' wide and approximately 20' long. I tried calling Heartland but they have not gotten back with me, still searching. I did a google search and found companies here in Dallas that sell the stuff but only in 5' x 12' pieces max. Anyone have any input on this one? Thx.
