They are one of the best bargins for flooring...very happy with mine as well as I have installed them on several different vans and they are great and easy to modify/cut. Stuff doesn't slide as much around on them as rubber floors and you can take them out and wash with a hose.
Rug wet down quickly and did cut down on the noise. (I will say hush mat on the wheel wells really cut down on the noise). The rug is fine for using it as a camping van providing some insulation and comfortable surface to walk on in bare feet.
The issue I have is a threshold for the slider and back doors. The only threshold I have found are steel which is not what I want. Would like to have a plastic one that clips on like in my Caravan.
