I'm thinking about buying the rear rubber molded mat From LMC for my 89 Blazer because carpet gets too dirty. Has anyone bought this and what kind of quality are we talking about. Will it last and does it cut down on the road noise much. Also, I'm wondering if I should just put it over my brand new carpet or take that out and spray adhesive it down and then when I do want carpet just put the carpet over top and the rubber mat will act like padding and sound deadener.Probably the only time I will want carpet will be when I'm camping and sleeping in the back. I took my backseat out and there is plenty of room for 2 adults, 1 child and 1 chihuaha.
