Yea a lot of us have done it including my self. We get it from stockinteriors.com. It requires a little bit of trimming to fit just right. But is very good quality.
I got the regular Plush and it is very good quality compared to the OEM stuff. I would say when you get it in, roll it out and let it sit like that for a few days. I didn't do that since I wouldn't of been able to keep my dogs off of it:bash:. It does take some trimming to get it to fit in the Cab, but once it's done it looks great.
I would assume the carpet gets dyed at the factory where they are made. As long as you get a quality dye it should work and look like it came that way. I have seen pictures of INFAMOU$ interior on here and the carpet looks great along with the rest of his interior. (post up some picutres oke
