My dog tore up the black matting on the door of my friends featherlite LQ. It's on the pass-thru door (horse side).  What is the best way to get replacement material.  She wants it to match exactly for trade in purposes.  Anyone have any ideas?

Just contact your Featherlite dealer....or a trailer parts/repairs shop. 

It may not match exactly, but we re-did the inside walls of my trailer with the matting purchased by the foot from Tractor Supply. They have big rolls of different thicknesses. We screwed them onto the walls with washer and screws. Looks great. Was about $300 to do the walls in a 3 horse trailer.
