I've got a 04 Tracker PT175, so I've got wood flooring with carpet, and aluminum hatch lids with carpet, all a med gray, maybe on the light side of medium gray. I usually keep my shoes and socks on during the summer just so my feet don't get burned, but I have sat down on the aluminum lids and felt the heat thru some thin nylon fishing pants I usually wear. I have not noticed near the heat transfer when I touch the carpet that covers the wood flooring. Aluminum will absorb heat even with carpet on it. You won't get a burn, but if you go barefooted, you'll be stepping quick imo.
