Just notched out the passenger side of our Hawk shell to install side dinette seats. Had to remove the original gray carpet and over a hundred tiny staples. Found a very close match at the local carpet store in Ocala. Bought a 8’ x6’ remnant for $40. Very close match. Looking at each side it hard to tell the difference.
Looked at the receipt but no details on the manufacturer. I would suggest paying a local carpet shot a look with a sample of the original in hand.
Sorry I couldn’t be of more help.
I've ordered matching cushion cover fabric from FWC (dovetail greystone). Maybe you can order the carpet from them if you want an exact match. Good luck!
I found the exact same carpet for my non silver spur 2017 shell model at home depot on the roll. Might want to check there. FWC doesn't use anything super special.
