Dave why would you rip the ply out ?
The ply save the internal panneling from getting damaged. I prefer ply on the floor as well as I had that plastic spray stuff put on the floor in one of my last vans which I found slippery, with the ply I found that a little water would just soak into it, it's not like the van gets flooded with water everyday. Well mine didn't anyway lol !!! 👍🇬🇧🇬🇧🇬🇧
