There is something like that, i have seen it in Jeep while visiting a junk yard.Just no easy answers. What I want is a form fitting thick mat like what used to be in pickup trucks years back. If it weren't for the heat issue, I'd do bed liner all day long - but the heat issue is real, so that's out. But I also absolutely, positively DO NOT want carpet or "rug" - such has NO business in a truck or Jeep.
Hmmm... Thinking out loud here - maybe form fitting rubber mats like weathertech combined with some generic rubber matting cut to fit over the tunnel - both laid over heat shield. Then again, the precise fit of the weathertechs might work against me. Dunno!
Pretty much a rubber mat, much thicker than bedrug, I have also found it online, but i can not remember where or who is the maker
